Federal Motor Vehicle Safety Standards; Lamps, Reflective Devices, and Associated Equipment

AGENCY: National Highway Traffic Safety Administration (NHTSA), Department of Transportation.

ACTION: Final Rule.

SUMMARY: This document amends the Federal Motor Vehicle Safety Standard (FMVSS) No. 108 on lamps, reflective devices, and associated equipment by reorganizing the regulatory text so that it provides a more straightforward and logical presentation of the applicable regulatory requirements, which includes the agency's interpretation of the existing requirements. It also greatly reduces the need to consult relevant third-party standards by including applicable requirements directly into the main body of Standard No. 108, rather than incorporating such provisions by reference. This final rule does not impose any new substantive requirements on manufacturers.

In addition, this document amends 49 CFR Part 564, Replaceable Light Source Information, by adding a newly created Appendix C, which relocates figures addressing sealed beam headlamps that currently reside in FMVSS No. 108 and a relevant Society of Automotive Engineers (SAE) standard there. We believe few lighting manufacturers still produce sealed beam headlamps, and their diminishing use is unlikely to draw new manufacturers of this type of lamp. Accordingly, we see no drawbacks to consolidating the information regarding sealed beam light sources with other light source information currently located in 49 CFR Part 564.

DATES: Effective date: The final rule is effective September 1, 2008 with voluntary early compliance permitted immediately. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of September 1, 2008. Petitions for reconsideration: Petitions for reconsideration of this final rule must be received not later than January 18, 2008.

ADDRESSES: Any petitions for reconsideration should refer to the docket number of this document and be submitted to: Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue, SE., West Building, Ground Floor, Docket Room W12-140, Washington, DC 20590.

   I. Executive Summary

   After carefully considering the public comments on its December 2005 proposal, the agency has decided to adopt a final rule amending Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, Reflective Devices, and Associated Equipment, by reorganizing the regulatory text and directly importing requirements from applicable SAE standards currently incorporated by reference into the regulatory text. In doing so, the agency has decided to make some changes from the NPRM, including modifying the organizational structure of the standard, relocating test procedures and performance requirements from attached tables to the regulatory text, and incorporating the substance of several additional interpretations into the standard. In addition, three SAE documents that the agency had proposed to continue to be incorporated by reference in the NPRM have now been integrated into the regulatory text, and the location of marking requirements within the standard has been further consolidated.

   Consistent with the NPRM, the final rule also establishes an Appendix C in 49 CFR Part 564, Replaceable Light Source Information, as a repository for dimensional and electrical information associated with standardized sealed beam headlamps that currently resides in figures in FMVSS No. 108.

   These modifications have furthered the objective of this rewrite by increasing clarity as follows: (1) Making requirements easier to find and comprehend; (2) presenting performance requirements and test procedures together through the inclusion of relevant provisions of third-party documents (previously incorporated by reference) directly into the regulatory text of the standard; and (3) updating Standard No. 108 to reflect significant letters of interpretation. The rewrite of FMVSS No. 108 is considered administrative in nature because the standard's existing requirements and obligations are not being increased, decreased, or substantively modified. Accordingly, costs associated with manufacturer compliance with Standard No. 108 are not expected to change as a result of this regulatory action.

   II. Background

1. Historical Overview of the Standard

   On December 30, 2005, NHTSA published a notice of proposed rulemaking \1\ (NPRM) to amend FMVSS No. 108, Lamps, Reflective Devices, and Associated Equipment, by reorganizing the regulatory text so that it provides a more straight-forward and logical presentation of the applicable regulatory requirements. The initial version of FMVSS No. 108 was adopted almost 40 years ago to increase motor vehicle safety by establishing minimum requirements for vehicle lighting, reflective devices, and associated equipment. In developing the standard, NHTSA incorporated requirements from a number of industry consensus standards, in particular SAE standards. At that time, motor vehicle technologies were relatively simple, as compared to today's designs. For example, motor vehicle headlighting systems were limited to ones consisting of either two

   [[Page 68235]]

   7-inch or four 5\3/4\-inch round sealed beam units. During the ensuing years, a number of rectangular sealed beam units, replaceable bulb headlamps, and integral beam headlamps were developed, and FMVSS No. 108 was amended to permit the use of these new technologies. Later, the standard was further amended to add requirements for high-mounted stop lamps, side marker lamps, and side reflex reflectors, to allow for daytime running lamps, and to address the conspicuity needs of large vehicles.

   \1\ 70 Fr 77454, (Dec. 30, 2005) (Docket No. NHTSA-2006-23634- 3).

   However, such amendments were made on an ad hoc basis, which, over time, resulted in a patchwork organization for FMVSS No. 108. Furthermore, when regulated parties had questions regarding how FMVSS No. 108 should be interpreted (in many instances due to rapid advances in lighting technology not fully anticipated or addressed by the existing regulatory text), they submitted requests for interpretation to the agency on specific issues. Since its promulgation, a large number of interpretation letters have been issued pertaining to Standard No. 108. Thus, in its current state, FMVSS No. 108 has requirements that are located directly in its regulatory text, located in referenced and sub-referenced SAE standards, and elaborated upon in various agency interpretations. Since its inception, NHTSA has never completed a thorough reorganization of the entire standard.

2. The Need for an Administrative Rewrite of the Standard

   Due to concerns about being able to locate requirements efficiently and the apparent lack of clarity associated with the standard (as demonstrated by an abundance of letters of interpretation), we decided to undertake an administrative rewrite of FMVSS No. 108. The agency has also received complaints that the current text of FMVSS No. 108 sometimes results in confusion, in part due to the way it is organized. Regulated parties have stated that the current organization of FMVSS No. 108 makes it difficult for them, at times, to be fully confident that all applicable requirements have been identified and satisfied prior to certification to the standard. Also, numerous interested parties have stated that the large number of interpretations that have been issued by the agency regarding Standard No. 108 make it difficult to locate and identify the agency's position on relevant issues. In addition, regulated parties have conveyed to the agency in recent years that some of the older versions of SAE standards incorporated by reference into FMVSS No. 108 are no longer readily available from SAE International.

   Throughout the past few decades, SAE has published revised, successor versions, with differing requirements, for many of their standards incorporated by reference into FMVSS No. 108. This appears to sometimes cause confusion on the part of regulated parties who, mistakenly, may believe that the most recent version of a SAE standard represents the regulatory requirement. The agency believes that interested parties should have easy access to the requirements of the standard, and, therefore, we believe there is value in publishing, without substantive change, applicable requirements that are currently contained in third-party documents directly within FMVSS No. 108 itself. The same logic applies to our decision to include the results of relevant legal interpretations in the standard. Furthermore, several provisions currently in Standard No. 108 refer to regulatory inception dates that are several years in the past, so the agency is eliminating text citing such past dates.

   For these reasons, we believe that the benefits of an administrative rewrite of FMVSS No. 108 (e.g., making the standard more navigable and thereby facilitating compliance with existing requirements) justify the necessary commitment of agency resources to accomplish this reorganization of the standard.

   III. December 2005 Notice of Proposed Rulemaking (NPRM) and Public Comments

1. The NPRM

   As noted above, NHTSA published a NPRM on December 30, 2005 that proposed to reorganize FMVSS No. 108 to improve the clarity of the standard's requirements, thereby increasing its utility for interested parties. This administrative rewrite attempted to make the standard more understandable by adopting a simplified numbering scheme, to improve organization by grouping related materials in a more logical and consistent sequence, and to reduce reliance on references to third- party documents. As proposed, the reorganized standard progressed from vehicle-level requirements to device-level requirements, beginning with the most common requirements and then proceeding to exceptions.

   The NPRM also proposed to move figures addressing sealed beam headlamps that are currently included in FMVSS No. 108 and SAE J1383 APR85, Performance Requirements for Motor Vehicle Headlamps, into 49 CFR Part 564, Replaceable Light Source Information, as a newly created Appendix C. This modification would be consistent with the current practice of placing replaceable light source information in Part 564. The title of Part 564 would also be changed to ``Replaceable Light Source and Sealed Beam Headlamp Information'' to reflect the addition of the sealed beam headlamp content.

   Whereas Standard No. 108 currently references approximately 35 different SAE documents in nearly 100 separate instances, the NPRM proposed reducing that number to eight documents, which were ones believed not to be routinely used by regulated parties. Accordingly, the NPRM proposed to incorporate the content of these frequently used SAE documents directly into the regulatory text and/or attached tables of Standard No. 108.

   The proposed tables included Table I, which listed the required lamps and reflective devices for the various vehicles regulated by FMVSS No. 108. The number of required lamps and reflective devices, their color, their mounting locations and height above the road surface, and their manner of activation were included in Table I, which resembles an expanded version of Tables I through IV of the current FMVSS No. 108. Table II detailed the requirements for the four different kinds of headlighting systems permitted by the standard. Table III contained the conspicuity system requirements for large trucks and trailers, while Tables IV and V provided, respectively, effective projected luminous lens area requirements and visibility requirements. Tables VI through XII and XIV through XX listed photometric requirements for individual lamp types. Table XIII detailed the target locations for license plate lamp photometry. Table XXI contained test procedures and performance requirements for all associated devices. Finally Tables XXII and XXIII contained non- photometry test procedures and performance requirements for all lamps, reflective devices, replaceable light sources, and vehicle headlamp aiming devices (VHAD). In addition, several new figures were included to clarify some of the application requirements for conspicuity systems.

   From a regulatory perspective, it was the agency's intention, as expressed in the NPRM, that the administrative rewrite of Standard No. 108 would neither result in any current obligation being diminished, nor any new obligation being imposed. In other words, the substantive requirements are identical to those of the current version

   [[Page 68236]]

   of FMVSS No. 108, including incorporated documents. Therefore, we do not believe that vehicle manufacturers and lighting manufacturers would have to make any changes to their respective products or production processes if the NPRM were made final.

2. Public Comments Received in Response to the NPRM

   The agency received comments from twenty seven entities in response to the December 2005 NPRM, which were submitted by 11 lamp or lamp component manufacturers, 11 manufacturer or user associations, three vehicle manufacturers, and two test organizations. Commenters included: Truck Manufacturers Association (TMA), Motorcycle Industry Council (MIC), Koito Manufacturing Co., Ltd., (Koito), Truck Trailer Manufacturers Association (TTMA), General Electric Automotive Plastics (GE-Plastics), General Motors North America (GM), Specialty Equipment Market Association (SEMA), Grote Industries, L.L.C., (Grote), Innovative Lighting, Inc., Calcoast Industrial Testing Laboratory (Calcoast), General Electric Automotive Lighting (GE), Valeo Sylvania, L.L.C. (VS), Guide Corporation (Guide), Alliance of Automobile Manufacturers (AAM), 3M Traffic Safety Systems (3M), Valeo Lighting Systems (Valeo), Association of International Automobile Manufacturers (AIAM), Owner-Operator Independent Drivers Association, Inc. (OOIDA), Atlas Material Testing Solutions (Atlas), American Trucking Associations, Inc. (ATA), Honda Motor Co., LTD. (Honda), Nissan North America, Inc., (Nissan), and Bayer Material Science, L.L.C., (Bayer). A joint response was submitted by Motor and Equipment Manufacturers Association (MEMA), Transportation Safety Equipment Institute (TSEI), and Motor Vehicle Lighting Council (MVLC), collectively the Associations (ASSN). Several months after the comment closing date the Associations submitted a supplementary response which was shortly followed by another supplementary response in conjunction with the Alliance (AAM/ASSN). All comments are available in Docket No. NHTSA- 2006-23634 and were considered in the promulgation of this final rule.

   The comments about the NPRM that we received can be divided into five general categories: (1) Administrative Considerations; (2) Omissions, Typographical Errors, and Inconsistent Language; (3) Organizational Structure; (4) Suggestions Beyond the Scope of the Rewrite; and (5) Suggestions Within the Scope of the Rewrite. A summary and analysis of each issue identified is provided below.

   (a) 49 CFR Part 564

   We received only one substantive comment concerning the relocation of the sealed beam headlamp figures into a new Appendix C of Part 564 of this chapter. GE requested a separate NPRM for this purpose and that the drawings that would be filed in Appendix C be made available for review.

   We stated in Summary of the Proposal in the NPRM that the final rule adopting the rewrite of Standard No. 108 would occur concurrently with the relocation of the sealed beam figures to Appendix C of Part 564. We also provided, at the end of that notice, a complete listing of all the figures and where they currently reside in FMVSS No. 108 or SAE J1383 APR85, which is incorporated by reference in the current version of FMVSS No. 108, but we did not provide specific regulatory text for Appendix C in the NPRM. Ample opportunity was provided for public comment on this issue, so we are making the establishment of Appendix C of Part 564 of this chapter and the transfer of the identified figures to it part of the final rule. We believe that it would be beneficial for the sealed beam drawings to be relocated as part of this reorganization so that applicable requirements are transferred in an accurate manner, thereby satisfying our commitment not to change the existing requirements of the standard.

   (b) 49 CFR 571.108 1. Administrative Considerations

   Some of the comments submitted in response to the NPRM were not focused upon the substance of the rewrite but rather addressed administrative concerns. Several commenters requested statements of reassurance that ``* * * no substantive changes from existing requirements are intended,'' and ``* * * state that the existing body of interpretations is still valid.'' On these points, we clarify as follows. First we reiterate that the administrative rewrite, as expressed in this final rule, does not make any substantive changes to the requirements of Standard No. 108. Furthermore, as stated in the NPRM, not all letters of interpretation were appropriate for inclusion into the regulatory language of FMVSS No. 108. Generally, we excluded those that we concluded did not add value to the regulatory text (i.e., one without broad applicability). However, all existing letters of interpretation, whether or not they are specifically integrated into the FMVSS No. 108 final rule, continue to reflect the legal opinion of the agency unless they contradict the explicit regulatory text of the standard or were overturned by subsequent interpretations.

   AAM suggested that the final rule should not be mandatory until September 1st, one year after publication of the final rule. We have established September 1, 2008 as the mandatory compliance date, with voluntary early compliance permitted immediately.

   ATA, OOIDA, and TMA all expressed concern about conflicts between FMVSS No. 108 and the regulations of the Federal Motor Carrier Safety Administration (FMCSA). They requested that the rewrite of Standard No. 108 reconcile the differences that they perceive between it and the regulations of the FMCSA.

   The FMCSA has established regulations for lamps, reflective devices, and associated equipment for commercial vehicles in use and a few specialized types of commercial vehicles at time of manufacture. The FMCSA made significant revisions to its lighting regulations in 2005 \2\ and some substantive differences do exist between the lighting regulations of FMCSA and FMVSS No. 108. These differences may have the potential to cause manufacturers of lamps and reflective devices that fall under the jurisdiction of both NHTSA and FMCSA to pursue different design, manufacturing, and compliance processes to satisfy the regulations of both agencies. However, any attempt at reconciliation here would be outside the scope of the rewrite process. Recently, FMCSA issued a final rule \3\ in response to a petition for reconsideration to its August 15, 2005 final rule, which resolved the differences between its regulations and FMVSS No. 108, as interpreted in NHTSA's July 28, 2005 interpretation to Mr. Clarke,\4\ concerning auxiliary lamps mounted near identification lamps. Regulated parties may want to consider other approaches to address the remaining differences between FMVSS No. 108 and 49 CFR Part 393. One such approach could be to submit rulemaking petitions to NHTSA and FMSCA requesting reconciliation of the differences between FMVSS No. 108 and 49 CFR Part 393.

   2. Omissions, Typographical Errors, and Inconsistent Language

   Given the complexity of the proposed administrative rewrite of FMVSS No. 108, including the integration of the content of numerous SAE standards incorporated by reference into the regulatory text, some omissions and typographical errors occurred. Numerous comments were received identifying such occurrences. Accordingly, we have amended the regulatory text of the final rule to correct these errors.

   Some respondents have noted instances where they believe that the language of the regulatory text used in the NPRM was not faithful to the language and intent of the current FMVSS No. 108. In many instances where a claim of unfaithful language was made in the comments, the agency adopted a conservative approach, choosing to revise the language of the NPRM back to that of the original document in the final rule. Where such a revision was not made, we have stated our reasons for that decision.

   Two rather significant instances where contradictory regulatory language was found to exist in the current version of FMVSS No. 108 and its incorporated documents are discussed here. One has to do with the appropriate photometric requirement for a specific type of replaceable bulb headlamp and is discussed in detail in the section devoted to Table II. The other concerns the ratio between the stop lamp function and the taillamp function in a lamp where those functions are optically combined. The discussion related to Table IX contains an explanation of this issue. Both instances bolster our opinion that regulatory requirements should be stated once and only once in a document. Neither instance has ever generated an interpretation request nor did many respondents raise either issue in their comments to the docket. This reinforces our belief that, notwithstanding the existence of ambiguous regulatory language, the intent of the specific requirements was clear.

   Because correction of either situation would require a substantive change to FMVSS No. 108, we have decided to refrain from addressing these examples now. However, we may issue a notice of correction in the near future to address what we believe are mistakes and inconsistencies that have existed for some time in Standard No. 108. 3. Organization of the Standard

   The organizational structure of the reorganized standard, as presented in the NPRM, progressed from vehicle-level requirements to device-level requirements, beginning with the most common requirements and then proceeding to exceptions. Requirements in the rewrite of FMVSS No. 108 are consolidated into dedicated paragraphs. Paragraphs S1 through S4 were organized in the same manner as the present standard. S4, Definitions, was expanded to incorporate relevant definitions from the applicable SAE standards previously incorporated as part of Standard No. 108. Paragraph S5 addressed the remaining references to SAE standards. Vehicle-level requirements were located in paragraph S6, including requirements by vehicle type. Following that, requirements were organized with dedicated sections for each type of lamp and reflective device, beginning with signal lamps, reflective devices and associated equipment under paragraph S7, and headlamp and headlighting requirements under paragraphs S8 through S13, and S16 through S18. Paragraph S14 addressed aimability performance requirements, while paragraph S15 contained requirements for replaceable light sources (including references to Part 564). In order to make requirements easier to find, a Table of Contents was added as an appendix to the standard.

   The most detailed comments about the organizational structure of the standard were those in the supplementary response from the ASSN/ AAM, which recommended a significantly different organizational structure that would divide the content of FMVSS No. 108 into four sections. Under the ASSN/AAM structure, the first section would contain general and specific lamp requirements, and the second section would consist of Tables I, II, III, VI, VII, VIII, IX, X, XI, XII, XIV, XV, XVI (split into three separate tables), XVII, XVIII, XIX, and XX. However, there would be some format changes to lamp photometry tables and the addition of graphical illustrations of photometric test points. These commenters similarly suggested three new tables that would graphically illustrate the required photometric test points, lines, and areas associated with upper beam headlamps, lower beam mechanically aimed headlamps, and lower beam visually/optically aimed headlamps. The third section would contain all the figures of the NPRM as well as Table XIII, License Plate Lamp Target Locations, redesigned as Figure 19. The fourth section would be subdivided into five annexes which would contain photometric test procedures and the physical test procedures of Tables XXI, XXII, and XXIII.

   ASSN/AAM also suggested dividing Table I into five separate tables: one for vehicles less than 80 in (2032 mm) in overall width, another for vehicles 80 in (2032 mm) or more in overall width, one for trailers, one for motorcycles, and one for school buses. The activation requirements would be removed from these tables and located in a new paragraph titled ``Electrical.'' Tables IV and V covering projected luminous lens area and visibility would be eliminated and their requirements dispersed to the applicable individual lamp sections. These individual lamp sections would have a common format divided into 14 subsections representing specific requirements. An additional table would be created that would contain all marking requirements.

   In consideration of the comments submitted by ASSN/AAM, we have decided to make significant changes to the structure of the standard presented in the NPRM. These structural changes include: (1) Relocating test procedures and performance requirements that were primarily contained in paragraph S6.8 and Tables XXI, XXII, and XXIII of the proposal, to paragraph S14 of the final rule; (2) expanding and standardizing the presentation of requirements in individual lamp and reflective device sections of the final rule beyond that of the proposal; (3) including the provisions from additional SAE documents, incorporated by reference in the proposal, in the regulatory text of the final rule; and (4) further consolidating the location of marking requirements in the final rule beyond that of the proposal.

   We believe there is value in adopting a structure in the final rule that is easy for regulated parties to navigate. There were some aspects of the ASSN/AAM recommended structure that we did not adopt due to our effort to avoid redundancies, streamline the standard, and avoid adding new material not currently contained in Standard No. 108, including graphs, which could cause confusion. We believe that our approach in modifying the structure of the NPRM will collectively provide the most value to all end-users.

   We have decided to adopt the ASSN/AAM recommendation regarding reorganization of the layout of several photometry requirement tables for reasons that follow. Standard No. 108 provides two alternative methods for demonstrating the photometric compliance of turn signal lamps, taillamps, stop lamps, backup lamps, parking lamps, and high- mounted stop lamps. For these lamps compliance can

   [[Page 68238]]

   be demonstrated by achieving a minimum photometric intensity at each of 18 to 22 discrete test points distributed within a pattern about 20[deg] high and 40[deg] wide centered about the H-V axis.\5\ Alternatively, FMVSS No. 108 also permits these specific lamps to demonstrate compliance by meeting a minimum photometric intensity for groups of these test points. Individual test points in proximity to each other are organized into groups consisting of from two to six points. The minimum photometric intensity requirement of each group is approximately (but not always exactly) the arithmetic sum of the minimum photometric intensities of all included points. This allows a lamp where one or more test point(s) in a group do not meet their individual minimum values to be compliant provided the remaining test points in the group exceed their minimum values by enough to allow the group total to exceed the group requirement.\6\ Turn signal lamps, taillamps, stop lamps, and parking lamps have five groups of test points; while backup lamps have six groups, and high-mounted stop lamps have four groups.

   \5\ The pattern is wider for backup lamps and tighter for high mounted stop lamps.

   \6\ No individual test point photometric intensity can fall below 60% of the point requirement when the group photometric method is used. In addition, photometric values between adjacent test points are regulated.

   Tables VI, VII, VIII, IX, XII, XV, which detail photometry requirements for those lamps permitted to use both the individual test point and the grouped test point compliance methods, are formatted such that test points are organized in group order. Progressing from left to right horizontally, each test point group is identified by number, and then the individual test points included within that group are identified by their vertical and horizontal positions. Next, the minimum photometric intensity for each individual test point is shown, and finally, at the right end, the group minimum photometric intensity is shown.

   In contrast, the photometry requirements tables suggested by the ASSN/AAM, and endorsed by Calcoast, organize the lamp test points in a vertical, then horizontal, manner that requires the user to search for each point to include in a group and then consult a sub-table to find out the minimum photometric requirement for that group. We find this suggested approach unnecessarily complex and prone to increasing, not decreasing, the possibility of error in determining photometric requirements. Therefore, we have decided to retain the format of the photometric tables as presented in the NPRM with one simplification, which was to locate the horizontal and vertical test point positions in the same relative positions in each table.

   Calcoast suggested, and we agree, that the horizontal test point positions and the vertical test point positions should always appear in the same columns. In our earlier proposal, this was not the case, and we have made modifications consistent with Calcoast's suggestion. The final rule designates the horizontal test point positions in a column to the left of a column that designates the corresponding vertical test point positions.

   Nissan suggested that those lamps that are permitted to demonstrate photometric compliance by either the individual test point method or the grouped test point method have the required photometric intensity values for each individual test point reduced to 60 percent of the current requirement and only allow use of the grouped test point method. We did not adopt this suggestion because it would have reduced the number of compliance methods available to manufacturers, a substantive change beyond the scope of this administrative rewrite.

   The original response from the ASSN, as well as the comments from Guide, suggested abandoning Tables XVIII and XIX and incorporating headlamp photometry requirements in a series of tables similar to the current FMVSS No. 108. We were not persuaded that more headlamp photometric tables would add value to the standard. Upper beam headlamp requirements are not related to whether a headlamp is mechanically or visually/optically aimed and six beam patterns adequately cover all headlamps. Many photometric test points are common to all lower beam headlamps. Tables XVIII and XIX present all required beam patterns (except for certain motorcycle headlamps) in a clear and concise format. Table II directs the user to the appropriate beam pattern in Tables XVIII and XIX. We retained this format for headlamp photometry requirements in the final rule.

   Several commenters mentioned inconsistent use of a ``no requirement'' indicator where a test point appears in a photometry requirements table but there is no value required at that point. Our proposal used both a blank space and a N.R. notation. In the final rule, we have adopted a consistent indicator that there is no requirement for a test point. A dashed line (-) is used exclusively for this purpose in photometry requirements tables.

   Commenters generally favored the use of tables in the NPRM for presenting performance requirements. However, Nissan, Grote, and TTMA all commented that Table I was too lengthy and should be separated into several sections based on common content. The Alliance suggested splitting Table XXIII into three separate tables because it contains tests for three distinctive items: (1) Headlamps, (2) vehicle headlamp aiming devices (VHAD), and (3) replaceable light sources. The differentiation of content in Table II of the NPRM was mentioned as being a particularly appropriate method of providing distinction.

   Several commenters, including ASSN/AAM and Grote, noted that tables containing significant amounts of text, such as the test requirements in Tables XXI, XXII, and XXIII, would be difficult to use because of lengthy passages that contain several sentences and express several unique test conditions or requirements. We agree with these comments. The tabular format is best suited to displaying quantitative values or short textual requirements. In the final rule, we moved virtually all test procedures and performance requirements to S14, the last section of the standard. Specifically, the content of Table XXI of the NPRM has been moved to S14.9, Associated Equipment Physical Test Procedures and Performance Requirements, the content of Table XXII of the NPRM has been moved to S14.3, Motorcycle Headlamp Out of Focus Test Procedures and Performance Requirements, S14.4, General Test Procedures and Performance Requirements (consisting of the color test and plastic optical materials test), and S14.5, Signal Lamp and Reflective Device Test Procedures and Performance Requirements. In addition, the content of Table XXIII of the NPRM has been moved to S14.6, Headlamp Physical Test Procedures and Performance Requirements, S14.7, Replaceable Light Source Physical Test Procedures and Performance Requirements, and S14.8, Vehicle Headlamp Aiming Devices (VHAD) Physical Test Procedures and Performance Requirements.

   General test procedures and performance requirements that were located in S6.8 of the NPRM have been placed in S14.1 of the final rule. Similarly, the photometric test procedures of S6.8 of the NPRM are now in S14.2 of the final rule.

   In the final rule, we decided to split several of the tables into shorter, more distinctive, sections and we completely revised the content of Table III and Table XIII. Table I, Required Lamps and

   [[Page 68239]]

   Reflective Devices, is divided into three parts: (1) Table I-a for passenger cars, multipurpose passenger vehicles, trucks, and buses of all widths; (2) Table I-b for trailers, and (3) Table I-c for motorcycles. We decided upon sectioning Table I in this manner for several reasons. One is user diversity. Organizations that manufacture vehicles such as passenger cars, multipurpose passenger vehicles, trucks, and buses typically do not also manufacture trailers or motorcycles. Likewise, organizations that manufacture trailers typically do not manufacture self propelled vehicles, and those that manufacture motorcycles do not produce cars, trucks, or trailers. Some commenters suggested separate sections for narrow vehicles (less than 2032 mm in width) and wide vehicles (those 2032 mm or wider). However, several manufacturers produce both narrow and wide vehicles, sometimes as different optional versions of the same vehicle, such as pickup trucks.

   Another consideration was commonality. Both narrow and wide vehicles are required to be equipped with a headlighting system, turn signal lamps, taillamps, stop lamps, side marker lamps, side and rear reflex reflectors, backup lamps and license plate lamps. Narrow vehicles are required to have parking lamps and high-mounted stop lamps while wide vehicles are not. Similarly, wide vehicles must have clearance and identification lamps which are not required on narrow vehicles. This same distinction occurs between narrow and wide trailers, for which common content significantly surpasses differentiated content. Therefore, we have concluded that it is unnecessary to section Table I by vehicle width.

   We are retaining the title of the three sections of Table I as Required Lamps and Reflective Devices, even though one of the lamps listed in Table I-a, Daytime Running Lamp (DRL), is not a required lamp. The heading above the DRL listing clearly describes it as being permitted but not required. However, because the DRL, when installed, is regulated in all attributes listed in Table I, Number and Color, Mounting Location, Mounting Height, and Device Activation (unlike other non-required lamps), the agency decided that Table I is the appropriate location for it.

   The three sections of Table IV, Effective Projected Luminous Lens Area Requirements, are now identified as: (1) Table IV-a covering turn signal and stop lamps; (2) Table IV-b for high-mounted stop lamps; and (3) Table IV-c for school bus signal lamps. The four sections of Table V, Visibility Requirements of Installed Lighting Devices, now include: (1) Table V-a for backup lamps, high-mounted stop lamps, and school bus signal lamps; (2) Table V-b which contains the lens area option for turn signal lamps, stop lamps, taillamps, and parking lamps; (3) Table V-c which has the luminous intensity option for turn signal lamps, stop lamps, taillamps, and parking lamps; and (4) Table V-d that has older alternative requirements for turn signal lamps, stop lamps, and taillamps.

   Table VI, Front Turn Signal Lamp Photometry Requirements, was split into two sections in the final rule. Table VI-a contains the base front turn signal lamp photometry requirements and also the values for 2\1/2\ times the base photometry requirements while Table IV-b contains values for 2 times the base photometry requirements and 1 the base photometry requirements

   New Table XIII consisting of: (1) Table XIII-a, Motorcycle Turn Signal Lamp Alternative Photometry Requirements, and (2) Table XIII-b, Motor Driven Cycle Alternative Photometry Requirements, includes the stop lamp requirements for certain motor driven cycles previously part of Table IX in the NPRM, as well as alternative turn signal requirements for motorcycles noted in paragraph S7.1.1.1 and S7.1.2.1 of the NPRM but not previously tabularized. The three sections of Table XVI are now: (1) Table XVI-a, Reflex Reflector Photometry Requirements, (2) Table XVI-b, Additional Photometry Requirements for Conspicuity Reflex Reflectors, and (3) Table XVI-c, Retroreflective Sheeting Photometry Requirements.

   Table XIX has been split into Tables XIX-a, containing photometric requirements for lower beam patterns LB1M, LB1V, LB2M, and LB2V. Table XIX-b contains requirements for lower beam patterns LB3M, LB3V, LB4M, and LB5M while Table XIX-c contains requirements for lower beam pattern LB4V.

   As mentioned previously, the ASSN/AAM response proposed a common, templated organizational format for the individual lamp sections and expansion of their content to include 14 subsections representing specific requirements. The requirements that they suggested be included in each section include: (1) Number, (2) color of light, (3) arrangement, (4) position, (5) geometric visibility, (6) orientation, (7) effective projected luminous lens area, (8) electrical, (9) tell tale, (10) marking requirements, (11) other provisions, (12) plastic materials, (13) photometry, and (14) physical tests. Implementing this request presents a dilemma for several reasons. First, most of the requirements suggested to be listed in individual lamp sections are already stated in parts of Table I, Table IV, and Table V. Table I of the NPRM is an expansion of Tables I, II, III, and IV of the current version of Standard No. 108, tables which have been part of the standard for decades. The agency rarely receives questions or complaints about regulatory content contained in Tables I through IV, but instead, they are often considered the most useful feature of the current version. We received no comments, including the ASSN/AAM submission, which suggested elimination of Table I.

   We also believe that the suggestion of ASSN/AAM to remove the activation requirements from Table I and place them all in a new section titled ``Electrical'' was without merit. The activation requirements of the various types of lamps, like the other categories listed in Table I, are primarily vehicle-level requirements rather than device-level requirements, and are best presented along with those other requirements.

   Table V of the NPRM is a restatement of Figures 19 and 20 of the current version of Standard No. 108, which were added in a final rule \7\ published on August 11, 2004 which promulgated the current visibility requirements. The agency decided that it would not be appropriate to disperse the visibility requirements of Table V (and likewise the effective projected luminous lens area requirements of Table IV) into individual lamp sections. The primary reason was that in real world situations, many lamp functions are combined with other lamp functions, very often optically combined. It is not unusual for a vehicle to have a combination rear lamp where the taillamp, stop lamp, and rear turn signal lamp functions are optically combined. The same holds true for front turn signal lamps and parking lamps. The presentation of visibility requirements for all regulated lamp functions together in Table IV allows regulated parties to quickly determine the appropriate requirements for such combination lamps and perhaps aid the decision about which visibility alternative to use for certification.

   \7\ 69 FR 48805 (Aug. 11, 2004) (Docket No. 2004-18794-1).

   The decision to leave Tables I, IV, and V intact in the final rule means that adopting the ASSN/AAM template for individual lamp sections would result in large scale duplication of requirements in Standard No. 108. Duplication of the same requirement in more than one location in a regulatory document has the potential for

   [[Page 68240]]

   unintended consequences. We intended to avoid those consequences by having each discrete requirement only stated once in Standard No. 108.\8\

   \8\ See the discussions of Table II and Table IX for explanations of existing duplicated requirements in the current version of FMVSS No. 108.

   Therefore, to be responsive to the request of ASSN/AAM concerning the format of individual lamp sections while still maintaining the integrity of the standard by having only a single statement of each requirement, we have adopted the use of pointing statements. These pointing statements appear in those subsections of each lamp section where a requirement does exist but is stated in another location of the standard. For instance, in paragraph S7.4 pertaining to side marker lamps, subsections 7.4.1 Number, 7.4.2 Color of light, 7.4.3 Mounting location, 7.4.4 Mounting height, and 7.4.5 Activation, all conclude with the pointing statement ``See Tables I-a, I-b, and I-c.'' Similarly, S7.4.9 Markings points to S6.5 for details of the applicable marking requirements. S7.4.6 Effective projected luminous lens area, S7.4.7 Visibility, S7.4.8 Indicator, S7.4.10 Spacing to other lamps, S7.4.11 Multiple compartment and multiple lamps, and S7.4.12 Ratio all conclude with the term ``No requirement'' indicating a requirement for those specific items of lamp performance does not exist in Standard No. 108.

   The entire content of Table III of the NPRM, dealing with conspicuity systems, was moved to paragraph S8.2 of the final rule. A new Table III was created to serve as a compilation of pointing statements directed to the locations within the final rule where marking requirements reside. While some headlamp marking requirements were relocated to paragraph S6.5 in the final rule, a number of other marking requirements continue to be dispersed within the document. In these cases, we have decided that the marking requirements are best located near the specific items to which they apply. However, these locations are all identified in Table III and consultation with this table should lead the user to all applicable marking requirements.

   Grote suggested that lengthy paragraphs of regulatory text be simplified by splitting them into separately numbered sub-paragraphs, particularly where the requirements were diverse. In a number of instances, we have been able to create such separation. Regulatory provisions (including renumbered paragraphs) where this has been done include: S6.1.3, S6.1.4.2, S6.1.5.2, S6.2.6, S6.5.3.3, S6.5.3.4, S6.6, S7.1.1.11, S7.1.1.12, S7.1.2.11, S7.1.2.12, S7.1.3, S7.2.11, S7.3.11, S7.3.12, S7.3.15, S7.7.13, S7.7.15, S7.9.14, S8.2.1, S8.2.2.3, S9.3.4, S9.8, S10.14.2, S10.17.1.1, S10.17.1.2, S10.17.1.3, S13, S14.1.4, S14.2.1, S14.2.3, S14.2.4, S14.2.5, S14.4.1, S14.4.2, S14.5, S14.6, S14.7, and S14.9. We have included the term ``split for clarity'' or similar language, often parenthetically, numerous places in the discussion of revisions to note where a section of text from the NPRM was divided into several smaller sub-sections in the final rule but not otherwise revised.

   Guide submitted numerous suggestions for reorganizing the NPRM by the reassignment of certain paragraphs within the organizational framework of the NPRM. In several instances, the agency concluded that the Guide suggestion proved to be a more appropriate location for a paragraph than the location proposed in the NPRM. We have noted these reassignments in our discussion (but without attribution to a Guide suggestion in some cases). This has caused numerous changes in the paragraph numbers throughout the regulatory text. Where a requirement in the final rule was identified differently in the NPRM, we have indicated the previous paragraph number in the revision summary.

   A number of Guide's suggested reassignments were not adopted, because we decided that the applicable textual provisions were already situated in the most appropriate location. Again, we did not mention every such rejection of Guide's suggested ordering or our reasoning for such decisions. While we believe that the final rule's organizational structure is the optimal choice, we recognize that it is not the only choice. Often, some of the requirements of Standard No. 108 intermix several attributes of lamps. Such an example is paragraph S7.11.2.1 which contains requirements for a DRL spaced near a turn signal lamp (e.g., considerations for the actual separation distance, the luminous intensity of both the DRL and the turn signal lamp, whether the DRL is optically combined with a lower beam headlamp, and the activation properties of both the DRL and turn signal lamp). Requirements such as these do not fit neatly into a Mounting Location section or an Activation section, and their essence would not survive dispersion of the component requirements into these sections because of their interdependence on several diverse attributes.

   Another such situation involves the presentation of the requirements for conspicuity systems. The content of Table III of the NPRM was moved to paragraph S8.2 of the regulatory text to provide a more comprehensible presentation format. An argument could be made that this content should be split into two portions, one portion describing how conspicuity material is spaced and arranged and another portion describing where conspicuity material is to be placed on applicable vehicles. If this apportionment were made, the first portion could be considered a device-level requirement and the second portion a vehicle- level requirement. Dispersing conspicuity system content in this way may seem correct from an organizational perspective, but would be in conflict with the goals of the rewrite of Standard No. 108 to present the requirements in a straight forward and logical manner.

   Our guiding principle in organizing the structure of the FMVSS No. 108 final rule was to attempt to locate each requirement in the place where a user would be most likely to look for it. Accordingly, the final rule has been organized with the following major sections:

   S1 Scope. S2 Purpose. S3 Application. S4 Definitions. S5 References to SAE publications. S6 Vehicle requirements. S7 Signal lamp requirements. S8 Reflective device requirements. S9 Associated equipment requirements. S10 Headlighting system requirements. S11 Replaceable light source requirements. S12 Headlamp concealment device requirements. S13 Replaceable headlamp lens requirements. S14 Physical and photometry test procedures and performance requirements.

   4. Suggestions Beyond the Scope of the Rewrite

   Units of Measurements

   Several comments were received concerning the way quantities in the NPRM were measured, in terms of units. In some cases, measurements were only in metric units, others in only English units, and still others dual-dimensioned with both metric and English units. We note that this situation currently exists within Standard No. 108 and the SAE standards and Recommended Practices incorporated by reference. Such perceived inconsistencies in the final rule are the result of the agency's decision to make no substantive changes to Standard No. 108 during the rewrite process. This means stating measurements in their original form consistent with their original source documents, instead of attempting to convert and standardize the units.

   ASSN preferred dual English/metric measurements for every quantity and requested that both be provided in the final rule. The commenter also preferred that linear measurements be expressed in both inches and centimeters. AAM requested dual units with metric units followed by English units and the use of direct conversions to establish those measurements that were only stated in one unit in the NPRM. Nissan argued that in recent rulemakings, the agency has consistently listed measurements using metric units with English units referenced parenthetically. Nissan preferred linear measurements that were in millimeters, except for photometric test distances which should remain dimensioned in meters. Conversely, Grote recommended that measurements be expressed in inches followed by centimeters in parentheses, believing that the vast majority of current users continue to use English measurements. SEMA also supported dual units of measurements with a preference for centimeters rather than millimeters. In supplemental comments, AAM/ASSN requested all quantities in FMVSS No. 108 that are not now metric be converted to metric pursuant to Executive Order 12770 (Metric Usage in Federal Government Programs).

   The FMVSS No. 108 rewrite is considered an administrative action because existing requirements and obligations are not being increased, decreased, or substantively modified. The agency has decided that converting values and providing dual-dimensions is outside the scope of this final rule. The conversion process, in some cases, would result in substantive change in the current requirements of the standard. This is because such conversions rarely result in a whole number equivalent, but more likely in an unwieldy value with more digits than the value it was converted from. The converted unit may have a non-exact value requiring it to be truncated after several digits. Such rounding may have little effect on some attributes but significant effect on others. An additional complication is that some currently dual-dimensioned values in FMVSS No. 108 are not exact equivalents. For instance, the air pressure required to be applied to the replaceable light source in the replaceable light source pressure test is expressed as 70 KPa (10 psig). However, the English equivalent of 70 KPa is 10.152641661 psig and the metric equivalent of 10 psig is 68.9475728 KPa. Thus, a user may conclude that a replaceable light source may be compliant with the standard if it withstands a pressure of 68.9475728 KPa and not 70 KPa.

   Additionally, the comments received in response to the NPRM show that users of FMVSS No. 108 do not have a consistent preference for a particular approach regarding units of measurement. In consideration of our principle not to change any existing requirements, as well as the wide range of opinions on the best approach for dual-dimensioning, the agency decided to present values consistent with the current standard instead of choosing one of the suggested options. Photometric Maps

   As previously mentioned, the AAM/ASSN supplementary comments, the ASSN initial comments, and the NAL comments recommend inclusion of a number of new graphical maps that would show details of the requirements for the various photometric test patterns. The signal lamp maps would show the position of each individual test point and how those points are combined into groups. The headlamp maps would show individual test points, linear test elements, and zonal test elements.

   In reviewing the suggested graphical maps, it was unclear which test points were part of which zone. Furthermore, such maps are beyond the scope of the administrative rewrite. In addition, there were no compelling arguments presented addressing how their inclusion would advance the goals of the rewrite. Adding such graphical maps would provide redundant information, significantly increasing the risk of potentially conflicting requirements, and likely generate numerous interpretation requests, especially if users were confused by the new graphs.

   That is not to say that these types of illustrations have no value. They seem particularly well suited for use by design and manufacturing organizations use in their internal design standards or photometric test procedures documents. Standard No. 108, like all Federal Motor Vehicle Safety Standards, strives to present regulatory requirements in the clearest way possible. It is not intended to serve as an all- inclusive working guide for designing, testing, or manufacturing lamps, reflective devices, or associated equipment. NHTSA

   [[Page 68242]]

   anticipates that user organizations will carefully incorporate the requirements of FMVSS No. 108 into their internal working documents. Requests for New or Revised Definitions

   Commenters requested inclusion in the final rule of numerous definitions for specific terms. These include: ``center (of item),'' ``fixed body panel,'' ``four lamp type headlamp,'' ``hazard warning lamps,'' ``obstruction,'' ``rigid part of vehicle,'' ``separately lighted areas,'' ``two lamp type headlamp,'' ``special tools,'' ``tools ordinarily available,'' ``supplemental lamp,'' and ``auxiliary lamp.'' There was also a suggestion for a revised definition for the term ``color bleeding,'' alleging it could be mistaken for the term ``light bleed.'' A suggestion was also submitted for addition of definitions of all lamp types mentioned in the current version of FMVSS No. 108, with the specific example of fog lamp.

   In its initial submission, AAM suggested the final rule use the term ``* * * light source optical centers * * *'' in place of the term ``* * * light sources * * *'' and the term ``* * * optical centers * * *'' in place of the term ``* * * optical axes * * *'' as revisions that would be technology-neutral in the specific case of a series wired array of LEDs being considered a single light source per the January 5, 2006 letter of interpretation to AMECA.\9\ There were also suggestions that the term ``lighted section'' be used exclusively and in place of ``multiple compartment'' and ``multiple lighted area.'' Adopting any of these suggestions would have been a substantive action which would be beyond the defined scope of this rewrite. For this reason we have not adopted any of these suggested modifications in the final rule.

   5. Suggestions Within the Scope of the Rewrite SAE Documents

   A significant initiative of the FMVSS No. 108 rewrite was the incorporation of requirements contained in SAE Standards and Recommended Practices (currently incorporated by reference or sub- reference) directly into the body of the standard. The current version of Standard No. 108 relies heavily on the content of numerous SAE documents. It contains over 100 references to some 35 different SAE documents, many of which were issued in the 1960s. Some of these documents are incorporated in their entirety, whereas only portions of others are cited. The NPRM integrated much of the content of these SAE document directly into the regulatory language, resulting in only eight SAE documents continuing to be incorporated by reference.

   Generally commenters supported this action. SEMA requested that all referenced and sub-referenced SAE documents be included in the regulatory text of the final rule. While total elimination of documents incorporated by reference proved to be impractical, we did eliminate references to three additional SAE documents in the final rule as discussed below. We also restored a reference to SAE J567b, Bulb Sockets, in S14.2.1.6.2 of the final rule based upon comments by Calcoast. This reference exists in Footnotes 2 and 3, which follow Table IV, of the current version of FMVSS No. 108, but was eliminated in the NPRM. We agree with Calcoast that the exemption permitted in these footnotes stating that bulbs not listed in SAE J573d, Lamp Bulbs and Sealed Units, December 1968, are not required to use a socket that conforms to the requirements of SAE J567b, Bulb Sockets, April 1964, is needed in the final rule.

   SAE J577, Vibration Test Machine, April 1964, has been replicated as Figure 21, and all references to SAE J577 have been removed from the final rule. SAE J823b, Flasher Test Equipment, April 1968, describes a standard test circuit to be used in the performance testing of vehicular hazard warning signal flashers and turn signal flashers. This SAE standard also has specifications for power supplies used in these tests and describes the circuit adjustments necessary to perform valid tests. We have chosen to incorporate the content of SAE J823b into the final rule. New Figure 22, Flasher Standard Test Circuit, provides the test circuit schematic diagram from Figure 1 of SAE J823b. Paragraph S14.9.3.1 of the final rule states requirements for circuit adjustments applicable to flasher tests, and paragraph S14.9.3.2 provides separate power supply specifications for the various flasher performance tests. With the inclusion of paragraph S14.9.3 and Figure 22 in the final rule, all references to SAE J823b have been deleted.

   SAE J588e, Turn Signal Lamps, September 1970, incorporated by reference in FMVSS No. 108, is referenced in paragraph S5.1.1.1 of the current version of the standard solely to establish requirements for double-sided turn signal lamps installed on truck tractors. It was eliminated from the final rule by incorporating the content of paragraph 3.4 and a portion of paragraph 3.9.1 of SAE J588e into paragraph S6.1.1.3 of the NPRM. The remaining portion of paragraph 3.9.1 was incorporated in Table VII, Rear Turn Signal Lamp Photometry Requirements, of the NPRM by revision to Footnote 6.

   The revised paragraph S6.1.1.3 now reads, `` * * * A truck tractor need not be equipped with turn signal lamps mounted on the rear if the turn signal lamps at or near the front are of double-face construction and are located such that they meet the photometric requirements for double-faced turn signal lamps specified in Footnote 6 of Table VII.'' Continuing, paragraph S6.1.1.3.1 states, ``The flashing signal from a double-faced signal lamp must not be obliterated when subjected to external light rays from either in front or behind, at any and all angles.'' The revised Footnote 6 to Table VII now states, ``A double- faced turn signal lamp installed as described in paragraph S6.1.1.3 on a truck tractor need only meet the photometric requirements for a left side lamp where the lamp is mounted on the left side of the vehicle, and for a right side lamp where the lamp is mounted on the right side of the vehicle.''

   This same SAE standard, J588e, Turn Signal Lamps, September 1970, is cited in the current version of FMVSS No. 108 as containing the requirements for the illuminated pilot indicator for turn signal lamp failure. The NPRM had erroneously stated the requirements from SAE J588 NOV84, Turn Signal Lamps. Paragraph S9.3 of the final rule now correctly states the illuminated area of the indicator and the acceptable modes of indication. Consistent with these changes, all references to SAE J588e have been removed from the standard.

   We undertook the effort to eliminate these additional SAE references in the final rule in part because the nature of some comments suggested that the relationship between FMVSS No. 108 and its incorporated SAE documents causes significant confusion.

   One example of such confusion is found in the comments of Grote and Koito in reference to the limitations in applying reduced photometric requirements to adjacent front and rear side marker lamps. This section is based upon paragraph S5.1.1.8 of the current version of Standard No. 108 which states, ``For each motor vehicle less than 30 feet in overall length, the photometric minimum candlepower \10\ requirements for side marker lamps specified in SAE Standard J592e,

   [[Page 68243]]

   Clearance, Side Marker, and Identification Lamps, July 1972, may be met for all inboard test points at a distance of 15 feet from the vehicle and on a vertical plane that is perpendicular to the longitudinal axis of the vehicle and located midway between the front and rear side marker lamps.'' In this case, the limitation of vehicles less than 30 feet in overall length recognizes that those vehicles are ones where intermediate side marker lamps (and intermediate side reflex reflectors) are not required to be installed. Table 1 of SAE J592e, detailing the photometric requirements of side marker lamps, also contains a footnote ``b'' further limiting the vehicles where reduced photometric requirements can be applied. Footnote ``b'' states that, ``The requirements for side markers used on vehicles less than 80 inches (2 meters) wide may be met for inboard test points * * * '' This vehicle width limitation is reflected in Footnote 1 of Table X. This is an example where the text of an incorporated SAE document applies limitations beyond those contained in the text of FMVSS No. 108.

   \10\ The term ``candlepower'' used in this context means the contemporary unit of measurement used to express the luminous intensity attribute.

   Another example is illustrated in the comments by AAM and Koito about the spatial relationship between front turn signal lamps and certain other front-mounted lamps and the photometric requirements the relationship imposes on the front turn signal lamp as stated in paragraph S7.1.1.2 of the NPRM (S7.1.1.10 of the final rule). Current FMVSS No. 108, at paragraph S5.3.1.7, imposes a multiplier of 2.5 on minimum photometric intensity requirements for a front turn signal lamp mounted less than 100 mm from the lighted edge of a lower beam headlamp. Turn signal lamps are also required to be designed to conform to referenced standards SAE J588 NOV84 for vehicles less than 2032 mm in overall width and SAE J1395 APR85 for vehicles 2032 mm or more in overall width. These documents provide, in paragraph 5.1.5.4 of SAE J588 and paragraphs 5.1.5.4, 5.1.5.5, and 5.1.5.6 of SAE J1395, additional photometric requirements for turn signal lamps based upon their construction. The method the turn signal lamp uses to project light (i.e., whether it primarily uses a reflector to direct light or not) determines how the relationship is measured between the turn signal lamp and the lower beam headlamp, or a surrogate lower beam headlamp such as an auxiliary lower beam headlamp or a fog lamp. Based upon this measurement, the turn signal lamp may be required to have a multiplier of 1.5, 2.0, or 2.5 times the minimum photometric intensity. Thus, it is possible for a turn signal lamp not to be required to have increased intensity based upon paragraph S5.3.1.7 of current FMVSS No. 108 but still be required to have increased intensity because of its construction or proximity to another front lamp, such as a fog lamp. This is an example where an incorporated SAE document imposes requirements beyond those explicitly stated in the regulatory text of Standard No. 108.\11\

   \11\ The subject of turn signal lamp photometric requirements based upon spacing to other front lamps is discussed in several interpretations such as Matsui (9/20/95).

   In its comments, AAM stated that FMVSS No. 108 has never contained a requirement for a vehicular hazard warning signal pilot indicator as contained in paragraph S6.6 of the NPRM (paragraph S9.8 of the final rule). We note that this requirement came from SAE J910, Vehicular Hazard Warning Signal Operating Unit, January 1966, and SAE J945, Vehicular Hazard Warning Flasher, February 1966, both incorporated by reference in Tables I and III of the current version of FMVSS No. 108. The requirements from SAE J910 contained in paragraph 5 detail how the pilot indicator is to operate, how it can be combined with the turn signal indicator, and the size and color of a dedicated vehicular hazard warning signal pilot indicator. The requirements from SAE J945 describe how the means of providing the indication can be incorporated into the flasher if it functions under all test conditions applied to the flasher and how an audible indication can be used in conjunction with the visible indication. This is an example where incorporated SAE documents contain a requirement that is not expressly stated in the text of FMVSS No. 108.

   AAM also stated in its comments that only the lighting equipment requirements of SAE J587 OCT81, License Plate Lamps (Rear Registration Plate Lamps), are incorporated by reference in Standard No. 108 (i.e., in paragraph S5.1.1 of the current version). AAM argued that a license plate holder is not an item of lighting equipment and that requirements for the holder would also apply to a front license plate holder. In response, we note that SAE J587 OCT81 does contain specific requirements for a license plate holder and its relationship with the license plate, the surface the vehicle stands on, and the license plate lamp. The performance of a license plate lamp is dependent upon its physical relationship with the license plate. The license plate must be secured in position to evaluate this performance. To alleviate AAM's concern with application of the requirement to a front license plate holder, we have revised the text of paragraph S6.6.3 of the final rule (paragraph S6.1.1 of the NPRM) to state, ``Each rear license plate holder must be designed and constructed to provide a substantial plane surface on which to mount the plate. The plane of the license plate mounting surface and the plane on which the vehicle stands must be perpendicular within 15[deg] '' (emphasis added).

   Grote commented that lamps designed to conform to SAE J1395 APR85, Turn Signal Lamps for use on Motor Vehicles 2032 mm or more in Overall Width, and SAE J1398 MAY85, Stop Lamps for use on Motor Vehicles 2032 mm or more in Overall Width, incorporated by reference in Table I of the current version of FMVSS No. 108 for use on multipurpose passenger vehicles, trucks, trailers, and buses, of 80 or more inches in overall width, could also be used on vehicles less than 80 inches (2032 mm) overall width, without meeting the requirements listed in Table III for these lamps. Grote based its comment on a statement in the Scope of SAE J1395 stating that, ``Turn signal lamps conforming to this report may also be used on vehicles less than 2032 mm in overall width.'' The Scope of SAE J1398 has a similar statement concerning stop lamps. This assertion is simply not correct. Table III of the existing version of Standard No. 108 applies to all passenger cars and motorcycles, and multipurpose passenger vehicles, trucks, buses and trailers of less than 80 inches (2032 mm) in overall width. Table III clearly requires turn signal lamps to comply with SAE J588 NOV84 and stop lamps to comply with SAE J586 FEB84. Therefore, manufacturers may choose to design their lamps to also comply, respectively, with SAE J1395 APR85 and SAE J1398 MAY85, but they also must be designed to comply, respectively, with SAE J588 NOV84 and SAE J586 FEB84. We do not agree with the argument that compliance with only SAE J1395 APR85 and SAE J1398 MAY85, respectively, is permitted, because this clearly contradicts the language in the existing regulatory text.

   Table III of the current version of FMVSS No. 108 requires that all passenger cars and motorcycles, and multipurpose passenger vehicles, trucks, trailers, and buses, of less than 80 inches (2032 mm) in overall width must be equipped with lamps designed to conform to the requirements of SAE J588 NOV84, Turn Signal Lamps for use on Motor Vehicles Less Than 2032 mm

   [[Page 68244]]

   in Overall Width, and SAE J586 FEB84, Stop Lamps for use on Motor Vehicles Less Than 2032 mm in Overall Width. Thus, if a turn signal lamp or stop lamp is not designed to conform with SAE J588 NOV84 or SAE J586 FEB84 respectively, it cannot be used on any passenger car or motorcycle or on any multipurpose passenger vehicle, truck, trailer, or bus of less than 80 inches in overall width, no matter whether it also is designed to conform to SAE J1395 APR85 or SAE J1398 MAY85. The explicit requirements of FMVSS No. 108 prevail over any seemingly contradictory language of an incorporated third-party document.

   Observing the confusion that exists because the current version of Standard No. 108 relies so heavily upon reference to third-party documents, we are convinced that our action to remove those references to the maximum extent possible was a correct decision. Remaining references to SAE documents in the final rule include:

   S6.4.5 SAE J602, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units, August 1963 S9.3.5 SAE J941b, Motor Vehicle Driver's Eye Range, February 1969 S10.14.7.7 SAE J602 OCT80, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units S10.15.7.6 SAE J602 OCT80, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units S10.16.3.6 SAE J602 OCT80, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units S10.18.7 SAE J602 OCT80, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units S10.18.7.2 SAE J602 OCT80, Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units S11.3 SAE J2009 FEB93, Discharge Forward Lighting Systems S14.2.1.6 SAE J573d, Lamp Bulbs and Sealed Units, December 1968 S14.2.1.6.1 SAE J573d, Lamp Bulbs and Sealed Units, December 1968 S14.2.1.6.2 SAE J573d, Lamp Bulbs and Sealed Units, December 1968 S14.2.1.6.2 SAE J567b, Bulb Sockets, April 1964 S14.7.3.1.2 SAE J2009 FEB93, Discharge Forward Lighting Systems Cited Interpretations

   In the rewrite proposal, the agency integrated the clarifications provided by key letters of interpretation into the regulatory text of the standard. The criteria used in determining whether an interpretation was significant focused on whether it provided value in clarifying the provisions in the standard. In the vast majority of cases, past requests for interpretation have identified questions regarding applicability of certain provisions of the standard to specific design configurations. However, influential interpretations that clarified provisions of the standard, and continue to provide guidance to various parties beyond the original requestor, were believed to be particularly useful additions to the regulatory text. In the NPRM, the agency solicited public comment about additional interpretations that might be included in the final rule.

   In their submissions, several commenters mentioned specific interpretations of FMVSS No. 108 as candidates for incorporation in the regulatory text of the final rule. In two instances, we decided that the cited interpretations would make the standard more precise and added them to the final rule. The two interpretations are discussed below. Several commenters suggested other potential interpretations for inclusion into the final rule; however the agency decided that none of these provided enough value in clarifying the provisions of FMVSS No. 108.

   Nissan suggested that inclusion of the June 18, 1985 interpretation to Mr. Nakaya \12\ would more precisely define where the measurement of the height of a high-mounted stop lamp should be made with respect to the rear window of a passenger car. A more detailed description of this interpretation is found in the discussion of revised paragraph S6.1.3.2.1 of the final rule.

   \12\ http://isearch.nhtsa.gov/gm/85/1985-02.42.html_____________________________________-

   A suggestion of TTMA was to incorporate an interpretative rule \13\ published in 1999 into the standard. This interpretative rule quantifies the ``as near the top as practicable'' mounting requirement that applies to clearance lamps and identification lamps mounted on a vehicle with cargo doors. That rule states that NHTSA will presume it practical to mount these lamps above the cargo doors when the header above those doors extends at least 25 mm (1 inch) above them. A more detailed discussion of this issue is found in the discussion of Table I.

   \13\ 64 FR 16358, (April 5, 1999).

   Revisions to the Proposal S1 Through S3

   There were no comments submitted that related to S1, S2, or S3. S4 Definitions

   AAM objected to mounting and spacing criteria being part of the definitions of a clearance lamp, identification lamp, and side marker lamp. In response, we note that all three of these definitions are faithful to the applicable, long-referenced, SAE standards whose content we have included in both the proposal and final rule text. These mounting and spacing criteria serve to clarify the spatial function of the lamps and are appropriate parts of the definitions. Therefore, we are keeping these criteria in the final rule.

   We removed the third sentence from the definition of ``effective projected luminous lens area,'' stating the term ``functional lighted lens area'' appearing in any SAE document had an identical meaning. The single instance of the term ``functional lighted (lens) area'' appearing in the NPRM was in paragraph S7.1.1.2.2 (S7.1.1.10.3 in the final rule) in reference to the procedure to determine the measurement point for a front turn signal lamp with a reflector. We replaced ``functional lighted (lens) area'' in paragraph S7.1.1.10.3 with ``effective projected luminous lens area'' and were thereby able to remove any reference to ``functional lighted lens area'' in the standard.

   Nissan observed that the definitions for ``mechanically aimable headlamp'' and ``material'' were not in alphabetical order in the NPRM. We have corrected this in the final rule.

   GE commented that the definition of ``replaceable light source'' in the NPRM was not identical to that of the current version of FMVSS No. 108. As stated in the NPRM ``replaceable light source,'' means an assembly of a capsule, base, and terminals manufactured as a light source for an upper and/or lower beam of a replaceable bulb headlamp that is designed to conform to the requirements of Appendix A or Appendix B of 49 CFR part 564, Replaceable Light Source Information. The italicized text was added to the definition included in the current version of FMVSS No. 108 as part of an attempt to clarify that integral beam and replaceable bulb headlamps are allowed to incorporate ``replaceable light sources'' that are used for purposes other than headlighting. However these ``replaceable light sources'' are not those defined in S4, but rather ones typically used for non-headlighting functions such as turn signal lamps, parking lamps, and front side marker lamps. In the final rule, as explained later in the discussion of S10 Headlighting system requirements, we have decided to address this issue by revising how these non-headlighting light sources were described. Because the revisions in language in S10 should eliminate confusion between headlighting and non-headlighting replaceable light sources, there is no need to change the definition in S4 and it is identical in the

   [[Page 68245]]

   final rule to that of the current version of FMVSS No. 108.

   Nissan commented that the definitions for ``vehicular hazard warning signal flasher'' from SAE J945, Vehicular Hazard Warning Signal Flasher, February 1966, and for ``vehicular hazard warning signal operating unit'' from SAE J910, Vehicular Hazard Warning Signal Operating Unit, January 1966, described the function of the hazard warning signal system in slightly different ways. Nissan contended, and we agree, that the description of the operation of the hazard warning signal system should be consistent. Therefore, we have revised the definition of ``vehicular hazard warning signal flasher'' from `` * * * means a device which, as long as it is turned on, causes all the required hazard warning lamps to flash'' to `` * * * means a device which, as long as it is turned on, causes all the required turn signal lamps to flash.'' Similarly the definition of the ``vehicular hazard warning signal operating unit'' was revised from `` * * * means a driver controlled device which causes all turn signal lamps, or other hazard warning lamps, to flash simultaneously to indicate to approaching drivers the presence of a vehicular hazard'' to `` * * * means a driver controlled device which causes all required turn signal lamps to flash simultaneously to indicate to approaching drivers the presence of a vehicular hazard''. This revision recognizes that the hazard warning signal of paragraph S6.1.5.1 only requires simultaneous flashing of sufficient turn signal lamps to meet the turn signal photometric requirements of Standard No. 108. S5 References to SAE Publications

   In paragraph S5.2 of the NPRM we stated that ``A complete list of all SAE publications incorporated by reference in this standard are indexed at 49 CFR 571.5(j)''. This inclusion was in anticipation of a final rule based upon a NPRM \14\ that would have established 49 CFR 571(j) to contain this list. This final rule has not been issued. Therefore, we have deleted this reference from the final rule.

   \14\ 70 FR 36094, (June 22, 2005)(Docket No. 2005-21600-1).

   AAM requested that the word ``required'' be inserted into the first sentence of paragraph S5.1 between the words ``Each'' and ``lamp'' to be faithful to paragraph S5.1.1 of the current version of FMVSS No. 108 containing provisions for lamps, reflective devices, and associated equipment to be designed to comply with specific SAE Standards and Recommended Practices. We agree and have revised the final rule. S6 Vehicle Requirements

   Proposed paragraph S6.1.1.1.1, allowing conspicuity material on a trailer to also serve as the required reflex reflectors if the conspicuity material was placed at the required locations of the reflex reflectors, has been relocated into the Reflex Reflectors portion of Table I-b of the final rule.

   Paragraph S6.1.1.3 was modified as stated in the SAE Documents section above to fully integrate the requirements of SAE J588e, Turn Signal Lamps, September 1970, relating to the use of double-faced turn signal lamps on truck tractors. This amendment also required a revision to Table XII and its Footnote 6 as well as the addition of paragraph 3.9.1 of SAE J588e as paragraph S6.1.1.3 of FMVSS No. 108 and paragraph 3.4 of SAE J588e as paragraph S6.1.1.3.1 of FMVSS No. 108.

   Paragraph S6.1.1.4 of the final rule, (paragraph S6.2.4 of the NPRM), was moved into the Vehicle requirements section based upon the Guide comment that it was a more appropriate location than the Impairment section. A typographical correction was also made to clarify that a parking lamp or a fog lamp may not be used as a DRL. This correction now results in language that is faithful to the current version of FMVSS No. 108 at paragraph S5.5.11(a).

   Paragraph S6.1.1.4, Hazard warning lamps, of the NPRM describing activation provisions for hazard warning lamps was moved to the Activation section where it became paragraph S6.1.5.1 in the final rule.

   The phrase ``fixed body panel'' in proposed paragraph S6.1.3.1 was objected to by Koito as being more restrictive than the phrase ``rigid part'' which is used in the current version of FMVSS No. 108 at paragraph S5.3. We have decided to retain ``rigid part'' in the final rule to be faithful to the original language and meaning. The phrase `` * * * the mounting location and * * * '' has been added to paragraph S6.1.3.1 ahead of ``height'' to be consistent with the references to Tables I, II, III, and IV of the current version of FMVSS No. 108 as referenced at paragraph S5.3 of that document. This clarification was recommended by Guide.

   Guide also suggested that the requirements of the second sentence of paragraph S6.1.3 of the NPRM, which becomes paragraph S6.1.3.2 of the final rule, deal more with photometry than lamp mounting location. We do not agree with this suggestion. This requirement deals with how to consider, for photometry purposes, the individual compartments or lamps of an array that consists of portions on both rigid and non-rigid parts of the vehicle as described in the July 12, 2000, letter of interpretation to Mr. King.\15\ Because this provision establishes photometric performance requirements based upon what kind of surface a lamp is mounted upon, its inclusion in the Mounting location section is appropriate. We have added a pointing statement in paragraphs S7.1.1.11.1 (front turn signal lamps), S7.1.2.11.1 (rear turn signal lamps), S7.2.11.1 (taillamps), and S7.3.11.1 (stop lamps) in the final rule to direct users to this requirement. Guide also stated that this section should also apply to the rear reflex reflector. However, as stated in several interpretations, reflex reflector requirements must be met by single reflectors, not a combination of separate reflectors. Supporting this position is the May 23, 2003 letter of interpretation to Mr. Babcock \16\ as well as the April 14, 2004 letter of interpretation to Mr. Strassburger.\17\

   Paragraph S6.1.4, License plate lamp, of the NPRM has been relocated to paragraph S6.1.3.3 of the final rule in recognition that it states a requirement for mounting location.

   Paragraphs S7.9.1, Accessibility, and S7.9.2 Interior mounting, (duplication at S6.1.3.2.2 deleted) of the NPRM referring to high- mounted stop lamps (HMSL) were relocated in the final rule to be paragraphs S6.1.3.4.2 and S6.1.3.4.1 respectively. These requirements relate primarily to how the HMSL is mounted to the vehicle, so paragraph S6.1.3 is the most appropriate location in Standard No. 108 for them.

   Guide commented that the content of paragraphs S8.1.3 and S8.1.4 of the NPRM, dealing with headlamp beam mounting, belonged in that part of Standard No. 108 related to lamp mounting location. We agree and have moved them intact to become paragraph S6.1.3.5 of the final rule.

   Grote, Guide, Innovative, TMA, and TTMA all noted the typographical error in paragraph S6.2.5 of the NPRM. Both the title and text of this section contained the phrase ``* * * auxiliary identification lamp * * *'' which should be ``* * * auxiliary lamp* * *'' The correction has been made in the final rule, and this requirement has been relocated to the Mounting location

   [[Page 68246]]

   section as paragraph S6.1.3.6, as it states a mounting limitation.

   Paragraph S6.1.3.2.1 of the NPRM becomes paragraph S6.1.4.1, High- mounted stop lamp, in the final rule. Nissan suggested that the term ``window'' in the text had been defined more precisely in the June 18, 1985 letter of interpretation to Mr. Nakaya \18\ as ``glazing'' and suggested use of that term in the final rule. We agree and revised the text accordingly.

   \18\ http://isearch.nhtsa.gov/gm/85/1985-02.42.html_____________________________________-

   Guide commented that paragraph S6.1.5.1 of the NPRM, concerning optional activation of stop lamps by vehicle retarders, duplicated Table I. Upon review, we believe it is a duplication, and we have decided that Table I is the appropriate location for it. Therefore, in the final rule this allowance is included in the Stop lamp-Device Activation portion of Tables I-a, I-b, and I-c.

   We have relocated to paragraph S6.1.5.1 of the final rule the content of paragraph S6.1.1.4 of the NPRM stating requirements of the hazard warning signal. This is appropriate since, as we noted in our discussion of the definitions of vehicular hazard warning signal flasher and vehicular hazard warning signal operating unit, the only requirement of this system is simultaneous flashing of sufficient turn signal lamps to meet the turn signal photometric requirements of Standard No. 108.

   Another section relocated to S6.1.5, Activation, is paragraph S6.1.5.2 of the final rule, which details the requirements for simultaneous activation of lower beam and upper beam headlamps. These requirements had been included as paragraph S8.2 of the NPRM. We agree with the comment of Guide that this content was most appropriately located in the Activation section.

   We removed paragraph S6.2.3 of the NPRM, which addressed specific requirements for auxiliary lamps performing the function of a required lamp, from the final rule. Grote, Guide, SEMA, and TMA persuaded us that the proposed S6.2.3 contained language that was not faithful to the current version of FMVSS No. 108 and did not add to the understanding of impairment.

   Paragraph S14.2 of the NPRM was relocated to be paragraph S6.2.6 of the final rule. This section states the restrictions that apply to equipment in front of a headlamp lens. Paragraph S6.2, Impairment, was judged the most appropriate location for it. SEMA suggested revising the language of this section in a way that was inconsistent with the current version of Standard No. 108 by allowing obstructions if some undefined visibility requirement were met. This suggestion would be a substantive change outside the scope of this rewrite project, and, as such, was not adopted in the final rule.

   As previously mentioned, paragraph S6.2.4 of the NPRM stating the requirements for DRLs was relocated to be paragraph S6.1.1.4 of the final rule.

   The text of paragraph S6.3, Equipment combinations, of the final rule remains identical to that of the NPRM.

   Paragraph S6.4, titled Visibility and aiming in the NPRM, was re- titled Lens area, visibility and aiming in the final rule, recognizing the lens area requirements of paragraph S6.4.1. References in paragraph S6.4 to Table IV were revised in the final rule to reference Table IV- a, Table IV-b, or Table IV-c, as appropriate.

   AAM and Koito commented that the requirement of a manufacturer to irrevocably certify compliance to one of the visibility options of paragraph S6.4.3 was on a ``lamp function'' basis rather than a ``lamp'' basis as stated in the NPRM. We agree and have revised the text of paragraph S6.4.3 accordingly to bring it in conformity to the final rule \19\ establishing these visibility requirements.

   \19\ 69 FR 48805 (August 11, 2004) (Docket No. 2004-18794).

   Nissan objected to the title of paragraph S6.4.4, SAE visibility alternative, of the NPRM stating they did not like the use of the term SAE as part of that title. Considering one of the goals of the FMVSS No. 108 rewrite was to reduce reliance upon third party documents, particularly SAE documents incorporated by reference, we have eliminated ``SAE'' from the paragraph S6.4.4 title in the final rule. The title of this section in the final rule is Legacy visibility alternative recognizing that it contains requirements that have long been a part of Standard No. 108.

   Nissan also commented that paragraph S6.4.5, Low-mounted lamps, duplicated requirements stated in footnotes to Tables V-b, V-c, VI, VII, VIII, IX, XI, XIV, XVI-a, and XVII. We agree with Nissan that these footnotes are the appropriate location for these requirements and have eliminated this subparagraph from the final rule.

   The addition of a new Table III to the final rule as a repository for listing the location in the regulatory text of each marking requirement of Standard No. 108 is noted in paragraph S6.5.

   AAM and Koito noted that the regulatory requirement identified in paragraph S6.5.1 of the NPRM for the ``DOT'' marking was stated as ``the standard'' rather than ``49 U.S.C. 30115'' as stated in paragraph S7.2(a) of the current version of FMVSS No. 108. We have revised the text of this section in the final rule to be faithful to the existing language.

   Paragraph S6.5.2, DRL marking, has been revised in the final rule to include the phrase ``* * * on its lens * * *'' after ``DRL'' to be faithful to the marking requirement as stated in paragraph S5.5.11(a)(2) of the current version of FMVSS No. 108.

   Several sections of the NPRM containing marking requirements for headlamps have been relocated in their entirety and without revision to paragraph S6.5.3 of the final rule. These include: (1) Proposed paragraph S17.1 which becomes S6.5.3.1; (2) S17.2 which becomes S6.5.3.2; (3) S17.3 which becomes S6.5.3.3 (split into several sections for clarity); and (4) S17.4 which becomes S6.5.3.4 (split for clarity and updated section references). Similarly, proposed paragraph S17.5 summarizing the location of other headlamp marking requirements becomes paragraph S6.5.3.5.

   Proposed paragraph S6.6 stating requirements for associated equipment on regulated vehicles has been updated to indicate that the specific requirements for associated equipment are located in paragraph S9 of the final rule.

   Proposed paragraph S6.6.1, License plate holder, has been redesignated as paragraph S6.6.3 in the final rule due to renumbering of portions of paragraph S6.6 for clarity. AAM objected to this provision as stated previously in our discussion of SAE documents. The clarification that this section applied to rear license plate holders appears in the final rule (emphasis added).

   Paragraph 6.7, Replacement equipment, of the NPRM continues as that paragraph in the final rule. AAM, ASSN, and SEMA noted a typographic error in paragraph S6.7.1.2 where the word ``to'' inadvertently appears in the phrase ``* * * designed so that it does not to take the vehicle * * *'' (emphasis added). This error was corrected by removing that word from paragraph S6.7.1.2 of the final rule. SEMA commented that the language of paragraph S6.7 ``* * * infers that the standard would not preclude the installation of newer technologies on older vehicles and there is no suggestion that the introduction of lighting equipment into the marketplace is tied to vehicle manufacturer certification,''

   [[Page 68247]]

   and requested confirmation of this assumption by a response to its letter of December 16, 2005 requesting an interpretation by the Chief Counsel. SEMA's comment sought clarification of a notice of interpretation published in the Federal Register on November 1, 2005 \20\ rather than addressing the substance of the rewrite of Standard No. 108, and, thus, was beyond the scope of the rewrite. We note that SEMA's concern was addressed by the agency in an August 24, 2006 letter of clarification.\21\

   \20\ 70 FR 65972 (Nov. 1, 2005) (Docket No. NHTSA 03-15651).

   \21\ http://isearch.nhtsa.gov/files/SEMA.htm_____________________________________-

   In its comments, ASSN objected to the inclusion of the second sentence of paragraph S6.7.1.2 of the NPRM which states in part, ``* * * the determination of whether a vehicle would be taken out of compliance with this standard when an individual device is installed on the vehicle is made without regard to whether additional devices, including separate lamps or reflective devices sold together with the device, would also be installed.'' Its contention is that this language which ``converts its informal interpretation into a formal rule'' was included in the rewrite of FMVSS No. 108 without ``the required cost benefit analysis'' and would limit the ``opportunities for vehicle personalization.'' The incorporation of the replacement equipment interpretation of 70 FR at 65972, or any interpretation, does not constitute a change in the requirements of the standard. An interpretation simply clarifies the existing requirements of the standard and as such does not require the cost-benefit analysis or other rulemaking formalities as ASSN suggested. Regulated parties are bound by the regulatory requirements regardless of whether they are expressed in the regulatory text or in interpretations either by letter or publication. A vehicle owner can continue to modify the lighting on his vehicle, including obtaining devices for that purpose from regulated parties such as vehicle dealers, so long as the vehicle continues to meet the requirements of FMVSS No. 108 and the replacement lighting equipment provides all regulated functions of the device being replaced in a single unit.

   Grote also commented on paragraph S6.7, requesting that the provisions of paragraph S6.7.1.2 not be applicable to heavy vehicles. Grote was concerned that a replacement lamp, reflective device, or item of associated equipment which is designed or recommended for particular vehicle models must be designed per S6.7.1.2 so that it does not take the vehicle out of compliance with this standard when the individual device is installed on the vehicle. Grote suggested that in the heavy vehicle market that it primarily serves, an owner of a fleet of heavy vehicles may elect to remove the original equipment lamps and reflective devices and replace them with equally compliant lamps and devices but in different functional combinations. That means, for example, one of a set of original equipment lamps installed on a particular vehicle may contain the stop lamp, taillamp, and side marker lamp function, while the other separate lamp contains the turn signal lamp, backup lamp, and reflex reflectors. Grote would like to be able to recommend a set of replacement lamps for this vehicle where the individual lamps of the set do not have the required functions grouped in exactly the same combinations as those of the original equipment set.

   Grote believes that it should be permissible to do this because the agency stated in the interpretation \22\ published in the Federal Register on November 1, 2005 that, ``* * * while our interpretation of S5.8.1 [of the current version of FMVSS No. 108] is not dependent on the size of the vehicle for which a lamp is intended, it has a more limited application to aftermarket lighting equipment for heavy vehicles than to light vehicles.'' However, the agency continued the discussion by stating, ``The specific context of the questions asked by Calcoast was aftermarket combination lamps for light vehicles, such as passenger cars. These lamps are typically designed for specific models and can only be installed on those models in the same location as the lamps they replace. However, for heavy vehicles, lighting equipment is often generic and not designed for specific models. Truck-Lite, for example, commented on our notice of draft interpretation that it sells many kinds of lighting devices through catalog sales to hundreds of vehicle manufacturers whose equipment it has no way of knowing about. Consistent with our discussion in the October 2004 notice of interpretation, we note that our interpretation does not mean that the manufacturer of generic lighting equipment has the responsibility for ensuring correct selection and installation of its equipment. On the other hand, under our interpretation, a manufacturer of aftermarket lighting equipment could not design or recommend lighting equipment for a specific vehicle if the vehicle manufacturer could not have certified the vehicle using that lighting equipment instead of the lighting equipment it actually used.'' We did not suggest in this interpretation that when we spoke of a ``more limited application'' in reference to heavy vehicles, we intended to treat replacement lamps and reflective devices for heavy vehicles significantly different than those for light vehicles. We were merely pointing out that we did not consider manufacturers of generic lighting equipment responsible for ensuring the correct selection and installation of their equipment. Therefore, with the exception of the previously mentioned typographical error correction, paragraph S6.7 in the final rule is identical to that of the NPRM.

   \22\ 70 FR 65972 (Nov. 1, 2005).

   Proposed paragraph S6.8 of the NPRM has been relocated to be part of paragraph S14 of the final rule. Substantive issues raised in the public comments to the NPRM will be discussed in paragraph S14. S7 Signal Lamp Requirements

   Paragraph S7 of the NPRM contained specific requirements for signal lamps, reflective devices, and associated equipment. With the reorganization of the final rule, only the signal lamp requirements remain in S7. In some cases, the order of appearance of specific lamp types in S7 has changed from the NPRM.

   As previously mentioned, we have partially adopted the request of ASSN/AAM concerning the format of individual lamp sections. We have modified the individual signal lamp sections so that a series of specific types of requirements are listed for each lamp in the same order in a ``template'' format. These requirements, in order, are: (1) Number, (2) Color of light, (3) Mounting location, (4) Mounting height, (5) Activation, (6) Markings, (7) Effective projected luminous lens area, (8) Visibility, (9) Indicator, (10) Spacing to other lamps, (11) Multiple compartment and multiple lamps, and (12) Ratio. These are followed by sections on Photometry and Physical tests. In many cases, the text following one of these types of requirements will ``point'' to a table or another section of the standard. Also, there are numerous instances where the specific lamp has no performance requirement for a category, and the text states ``No requirement.''

   References to physical tests applicable to signal lamps contained in Table XXII of the NPRM have been revised in the final rule to refer to paragraphs S14.4 and S14.5.

   [[Page 68248]]

   Paragraph S7.1 of the final rule continues to contain the requirements for turn signal lamps. Paragraph S7.1.1.3 of the NPRM, addressing multiple compartment and multiple front turn signal lamps, becomes paragraph S7.1.1.11 in the final rule and has been split for clarity. In this section, Nissan stated that the term ``compartments'' after the word ``three'' was incorrectly plural; it has been changed to singular form in the final rule.

   As mentioned in the discussion of definitions, we replaced the term ``functional lighted area'' in paragraph S7.1.1.2.2 of the NPRM (paragraph S7.1.1.10.3 in the final rule), with the equivalent term ``effective projected luminous lens area.'' Since this paragraph was the only instance in Standard No. 108 where the term ``functional lighted area'' was used, it was eliminated from the definition of ``Effective projected luminous lens area'' in the final rule.

   Calcoast objected to the language of paragraph S7.1.1.3.1 of the NPRM which stated, ``* * * overall width must meet the photometric requirements specified for a single section and not * * *'' photometric requirements for lamps installed on vehicles 2032 mm or more in overall width. In the final rule, we have changed this language in paragraph S7.1.1.11.4 to be faithful to the language of paragraph S5.1.1.12 of the current version of FMVSS No. 108. It now states, ``* * * overall width require measurement of the photometrics for the entire lamp and not.* * *'' This same issue was raised concerning rear turn signal lamps and stop lamps. Therefore, similar changes were made in paragraph S7.1.2.11.4 of the final rule for rear turn signal lamps and in paragraph S7.3.11.4 for stop lamps.

   Paragraph S7.1.1.3.2 of the NPRM (containing requirements for the ratio between the photometric intensity of a front turn signal lamp and that of a parking lamp or clearance lamp where optically combined) has become paragraph S7.1.1.12 in the final rule and has been split for clarity.

   Paragraph S7.1.2.2 of the NPRM (addressing multiple compartment and multiple rear turn signal lamps) becomes paragraph S7.1.2.11 in the final rule and has been split for clarity. Once again, Nissan stated that in this section, the term ``compartments'' after the word ``three'' was incorrectly plural; it has been changed to singular form in the final rule.

   Paragraph S7.1.2.3 of the NPRM (containing requirements for the ratio between the photometric intensity of a rear turn signal lamp and that of a taillamp or clearance lamp where optically combined) becomes paragraph S7.1.2.12 in the final rule and has been split for clarity.

   Paragraph S7.2.1.1 of the NPRM (addressing multiple compartment and multiple taillamps) becomes paragraph S7.2.11 in the final rule and has been split for clarity. Again, Nissan stated that in this section the term ``compartments'' after the word ``three'' was incorrectly plural; it has been changed to singular form in the final rule. Also, AAM and Koito commented that there was an incorrect reference to Table VII instead of Table VIII in the NPRM; this has been corrected in the final rule.

   Paragraph S7.2.12, Ratio, has been added in the final rule to point to the ratio requirements for rear turn signal lamps and stop lamps optically combined with taillamps.

   Paragraph S7.3.1.1 of the NPRM (addressing multiple compartment and multiple stop lamps) becomes paragraph S7.3.11 in the final rule and has been split for clarity. Again, Nissan stated that in this section the term ``compartments'' after the word ``three'' was incorrectly plural; it has been changed to singular form in the final rule.

   Paragraph S7.3.1.2 of the NPRM (containing requirements for the ratio between the photometric intensity of a stop lamp and that of a taillamp where optically combined) becomes paragraph S7.3.12 in the final rule and has been split for clarity.

   Koito commented about the limitation of the application of reduced photometry requirements of paragraph S7.4.1.1 of the NPRM to side marker lamps installed on vehicles less than 80 inches wide. This limitation is consistent with Table 1, footnote ``b'' of SAE J592e. A more comprehensive discussion of this issue is part of the section on SAE documents in this final rule.

   Paragraph S7.5.12, Ratio, has been added in the final rule to point to the ratio requirements for front and rear turn signal lamps optically combined with clearance lamps.

   Paragraphs S7.7.2, Photometry, and S7.7.1, Installation, of the NPRM (applicable to license plate lamps) have been split for clarity as paragraphs S7.7.13 and S7.7.15 respectively, in the final rule.

   A reference to new Figure 20, License Plate Lamp Measurement of Incident Light Angle, was added to paragraph S7.7.15.4 of the final rule (paragraph S7.7.1.1 in the NPRM.)

   Paragraphs S7.9.1, Accessibility, and S7.9.2, Installation, of the NPRM (applicable to high-mounted stop lamps) were relocated in the final rule to be paragraphs S6.1.3.4.2 and S6.1.3.4.1, respectively.

   Guide commented that paragraph S7.11.2.2(c) of the NPRM should be relocated to the DRL activation portion of Table I-a. We disagree. This requirement, which becomes paragraph S7.10.10.1(c) in the final rule, only specifies activation and deactivation of the DRL when the turn signal is activated on a vehicle where the DRL is in close proximity to a turn signal lamp. Given these constraints of limited application, its present placement in the final rule is the most appropriate location. A statement in the DRL activation portion of Table I-a does point to paragraph S7.10.10.1(c) to also alert users to this requirement. S8 Reflective Device Requirements

   Requirements for reflex reflectors located in paragraph S7.10 of the NPRM have been relocated to paragraph S8.1 in the final rule. Paragraphs S8.1.1 through S8.1.10 are categorized identically to the organizational template of signal lamps. However, a section covering multiple compartment lamp and multiple lamps and a section covering ratio are clearly not applicable to reflex reflectors and are not included. Paragraph S8.1.11, Photometry, replaces paragraph S7.10.1 of the NPRM, while paragraph S8.1.12, Physical tests, replaces paragraph S7.10.2 and paragraph S8.1.13, Alternative reflex material, replaces paragraph S7.10.1.1.

   References to physical tests applicable to reflex reflectors contained in Table XXII of the NPRM have been revised in the final rule to refer to paragraphs S14.4 and S14.5.

   The final rule combines the content of paragraph S7.12 and Table III of the NPRM into paragraph S8.2. Specifically, proposed paragraph S7.12 becomes paragraph S8.2, proposed paragraph S7.12.1 becomes paragraph S8.2.1, Retroreflective sheeting, (split for clarity), and proposed paragraph S7.12.1.1 becomes paragraph S8.2.1.3, Certification marking.

   Following this, the text of the proposed Application pattern- Alternating red and white materials-Retroreflective sheeting box of Table III is stated as paragraph S8.2.1.4, the text of the proposed Application location-Retroreflective sheeting box of Table III is stated as paragraph S8.2.1.5, and the text of the proposed Application spacing-Retroreflective sheeting box of Table III is stated as paragraph S8.2.1.6.

   3M commented that they believe that the use of the phrase ``* * * material is required to be installed * * *'' in both

   [[Page 68249]]

   the requirements for Application pattern-Retroreflective sheeting and Application pattern-Conspicuity reflex reflectors implies that there is only one method of meeting conspicuity requirements, not two alternative methods. To increase clarity of these alternative requirements, we have revised the first sentence of the Alternating red and white materials-Retroreflective sheeting, (now paragraph S8.2.1.4.1) requirement to read ``* * * where alternating material is installed * * *'' We have also eliminated the phrase ``Where alternating color material is required to be installed'' from the beginning of the first sentence of Alternating red and white materials- Conspicuity reflex reflectors section (now paragraph S8.2.2.2.1).

   3M also commented that the language in the Application pattern- White material-Conspicuity reflex reflectors section (paragraph S8.2.2.2.2 of the final rule) discussing the dimensional relationship between adjacent white conspicuity reflex reflectors would be more appropriately included in the Application location portion. We disagree because the requirements in the Application location portion refer to the location of the material on the vehicle while the requirements in the Application pattern portion only refer to the location of a reflector to an adjacent reflector.

   AAM commented that the language of the Application location- Retroreflective sheeting portion begins with the phrase ``Not permitted * * *'' which imposes a different requirement than paragraph S5.7.1.4 of the current version of FMVSS No. 108 which states ``* * * but need not be applied * * *'' We agree and have revised the requirement of the Application location-Retroreflective sheeting (now paragraph S8.2.1.5 in the final rule) to begin, ``Need not be installed, as illustrated in Figure 12-2, * * *''

   Proposed paragraph S7.12.1.2, Photometry, becomes paragraph S8.2.1.7 in the final rule with no substantive changes. The photometry requirements reference was updated to Table XVI-c and the photometry test procedure reference to paragraph S14.2.3.

   Proposed paragraph S7.12.2, Conspicuity reflex reflectors, becomes paragraph S8.2.2 and proposed paragraph S7.12.1, Certification marking, becomes paragraph S8.2.2.1 in the final rule.

   Following this, the text of the proposed Application pattern- Alternating red and white material-Conspicuity reflex reflectors box of Table III is stated as paragraph S8.2.2.2.1 and the proposed Application pattern-White material-Conspicuity reflex reflectors box of Table III is stated as paragraph S8.2.2.2.2. Regarding retroreflective sheeting, we have addressed the previously noted 3M comment about alternative methods of meeting conspicuity requirements by eliminating the phrase ``Where white material is required to be installed'' from the beginning of the first sentence of the Application pattern-White material-Conspicuity reflex reflectors (now paragraph S8.2.2.2.2) section.

   Proposed paragraph S7.12.2.2, Photometry, has become paragraph S8.2.2.3 (split for clarity) in the final rule.

   Paragraph S8.2.3 of the final rule contains the requirements for conspicuity systems installed on trailers that were part of Table III in the NPRM. Paragraph S8.2.3.1 (split for clarity) includes the requirements for the three conspicuity elements required on the rear of a trailer and paragraph S8.2.3.2 (split for clarity) states requirements for the alternating color side conspicuity treatment required on trailers.

   AAM requested that the specific grades of sheeting permitted be mentioned in the requirements for Trailer rear-Element 2-white, now in paragraph S8.2.3.1.2.1. Therefore, we have inserted the phrase ``* * * of Grade DOT-C2, DOT-C3, or DOT-C4 * * *'' between the word ``long'' and the word ``applied'' in the first sentence making the language of the requirement faithful to that of paragraph S5.7.1.4.1(b) of the current version of FMVSS No. 108.

   TTMA commented that certain tank trailers may not have a vertical surface suitable for installing the Trailer side-alternating red and white materials conspicuity material between 375 mm and 1525 mm above the road surface. If installed in a downward orientation, it would not be effective for its purpose. The requirement of this section states that the material must be installed in this height range if practicable and going beyond this range is permitted if it aids correct orientation. We believe that the language of paragraph S8.2.3.2.1 of the final rule, along with the illustrative examples of conspicuity treatment applied to tank trailers shown in Figure 11, adequately addresses this issue.

   Paragraph S8.2.4 of the final rule contains the requirements for conspicuity systems installed on truck tractors, which was part of Table III in the NPRM. Paragraph S8.2.4.1 (split for clarity) contains requirements for Element 1 (alternating color) and paragraph S8.2.4.2 (split for clarity) states the requirements for Element 2 (white). One mounting alternative for conspicuity treatment requirements in Truck tractor-Element 1 was inadvertently omitted from the NPRM. This material is allowed to be mounted to ``plates attached to the mudflap support brackets'' as stated in the current version of FMVSS No. 108 at paragraph S5.7.1.4.3(a). We have inserted this alternative mounting location after ``mudflap support brackets'' and before ``or on the mudflaps'' in paragraph S8.2.4.1.1 of the final rule. S9 Associated Equipment Requirements

   Section 7.14 of the NPRM, Associated equipment requirements, is relocated to paragraph S9 in the final rule.

   Koito and Nissan commented that the first sentence of paragraph S7.14.1 of the NPRM, now paragraph S9.1.1 of the final rule, virtually duplicated the definition of Turn signal operating unit in S4. We agree and removed that sentence from paragraph S9.1.1. Paragraph S9.1.2 of the final rule states that turn signal operating units must meet the applicable performance requirements of paragraph S14.9. These references are to paragraph S6.6 and Table XXI in the NPRM.

   Similarly, the first sentence of paragraph S7.14.2 of the NPRM, now paragraph S9.2.1 of the final rule, virtually duplicated the definition of Turn signal flasher in S4. We removed that sentence from paragraph S9.2.1. Paragraph S9.2.2 of the final rule states that turn signal flashers must meet the applicable performance requirements of paragraph S14.9. These references are to paragraph S6.6 and Table XXI in the NPRM.

   In the NPRM, paragraph S7.14.3 stated requirements for the turn signal pilot indicator. These requirements have been relocated to paragraph S9.3 (split for clarity) in the final rule. Paragraph S7.14.3.1 of the NPRM described the turn signal pilot indicator size and color requirements. These requirements were erroneously based on paragraph 5.4.3 of SAE J588 NOV84, Turn Signal Lamps for use on Motor Vehicles less than 2032 mm in Overall Width. These requirements should have been based upon paragraph 4.5 of SAE J588e, Turn Signal Lamps, September 1970, as specified by paragraph S5.5.6 of the current version of FMVSS No. 108. We have stated the correct requirements in paragraph S9.3.4 of the final rule. These corrected requirements include a visibility requirement that references SAE J941b, Motor Vehicle Driver's Eye Range, February 1969, rather than the incorrect reference to SAE J1050,

   [[Page 68250]]

   Describing and Measuring the Driver's Field of View, which was included in the NPRM.

   The incorporation in paragraph S7.14.3.2 of the NPRM of the language from the incorrect version of SAE J588 also caused the description of the modes of indication of the turn signal pilot indicator to be omitted as noted in the comments from AAM. We have corrected this in the final rule by inserting the phrase ``* * *by a ``steady on'', ``steady off'', or by a significant change in the flashing rate* * *'' into the text of paragraph S9.3.6.

   We also neglected in the NPRM to cite the reason for our use of the failure indication criteria of ``* * *minimum photometric performance specified in Tables VI or VII* * *'' rather than the text of paragraph S5.5.6 of the current version of FMVSS No. 108, which states that criteria as ``Failure of one or more turn signal lamps to operate* * *.'' The language incorporated in the NPRM came from the July 10, 1998 letter of interpretation to Mr. Binder.\23\ In that interpretation, the issue of how to indicate to the driver the failure of a turn signal lamp that consisted of a number of LED light sources was discussed. The failure indication criteria for this situation was stated in Binder in this way, ``If a light source fails in a turn signal lamp on a vehicle that is not equipped to tow a trailer, Standard No. 108 requires that the failure be indicated to the driver. We are not aware of any LED turn signals in use, or how manufacturers would design such a unit to comply with this requirement. However, we believe that a failure should be indicated to the driver at the point where an LED turn signal ceases to furnish the minimum photometric performance required by Standard No. 108.'' The statements in the Binder interpretation also apply to turn signal lamps using conventional incandescent light sources. If a turn signal lamp using an incandescent light source fails, it obviously has zero photometric output. Therefore, we adopted the language of Binder in the NPRM but omitted mention of it as one of the incorporated interpretations. We are correcting that omission here and are preserving the failure indication criteria of the NPRM in paragraph S9.3.6 of the final rule.

   \23\ http://isearch.nhtsa.gov/files/18121.ztv.html_____________________________________-

   Paragraphs S7.14.4, Headlamp beam switching device, and S7.14.4.1, Semi-automatic headlamp beam switching device, of the NPRM, were re- designated as paragraphs S9.4 and S9.4.1, respectively, in the final rule. Paragraph S9.4.1.4 of the final rule, which was paragraph S7.14.4.1.4 in the NPRM, had a second sentence added to it which states, ``The device shall not affect the function of the upper beam indicator light.'' which was inadvertently omitted from the NPRM. This requirement comes from paragraph 4.14 of SAE J565b, Semiautomatic Headlamp Beam Switching Devices, February 1969, which is incorporated by reference in the current version of FMVSS No. 108.

   Paragraph S9.4.1.7 of the final rule states that semi-automatic headlamp beam switching devices must be designed to conform to the performance requirements of paragraph S14.9. These references are to paragraph S6.6 and Table XXI in the NPRM.

   Paragraphs S7.14.5 Upper beam headlamp indicator, and S7.14.5.1 Indicator size, location, and color, of the NPRM, become paragraphs S9.5 and S9.5.1, respectively, in the final rule. However, the term ``color'' and the last sentence of paragraph S7.14.5.1 stating that the color of the indicator need not be red were deleted from paragraph S9.5.1. By removing this language and making Standard No. 108 silent about the color of the upper beam headlamp indicator, we have simplified the manner in which the requirement is presented. The current version of FMVSS No. 108 states in paragraph S5.5.2 that, ``Each vehicle shall have a means for indicating to the driver when the upper beams of the headlamps are on that conforms to SAE Recommended Practice J564a, April 1964, except that the signal color need not be red''. The second paragraph of SAE J564a states that ``* * *The upper beam indicator should consist of a red light* * *.'' As noted in the comments of AAM, we incorporated in the NPRM the requirements of SAE J564a directly into the text of the Standard No. 108 without including the red color requirement because of the noted exclusion. However, we neglected to remove the excluding language from the NPRM. We are doing so in the final rule.

   Koito and Nissan commented that the first sentence of paragraph S7.14.6 of the NPRM, now paragraph S9.6.1 of the final rule, virtually duplicated the definition of Vehicular hazard warning signal operating unit in S4. We agree and removed that sentence from paragraph S9.6.1. Paragraph S9.6.3 of the final rule states that vehicular hazard warning signal operating units must meet the applicable performance requirements of paragraph S14.9. These references are to paragraph S6.6 and Table XXI in the NPRM.

   Similarly, the first sentence of paragraph S7.14.7 of the NPRM, now paragraph S9.7.1 of the final rule, virtually duplicated the definition of Vehicular hazard warning signal flasher in S4. We removed that sentence from paragraph S9.7.1. Paragraph S9.7.2 of the final rule states that vehicular hazard warning signal flashers must meet the applicable performance requirements of paragraph S14.9. These references are to paragraph S6.6 and Table XXI in the NPRM.

   Requirements for the vehicular hazard warning signal pilot indicator from paragraph S7.14.8 of the NPRM are relocated intact to paragraph S9.8 (split for clarity) in the final rule. AAM commented that a vehicular hazard warning signal pilot indicator was not required by FMVSS No. 108. We direct AAM's attention to SAE J910, Vehicular Hazard Warning Signal Operating Unit, January 1966, specifically paragraph 5. When we removed J910 as a referenced document in the NPRM, we incorporated the requirements of paragraph 5 into paragraph S7.14.8, which we are now designating as paragraph S9.8 in the final rule. \24\

   \24\ SAE J945, Vehicular Hazard Warning Signal Flasher, February 1966 incorporated by reference in the current version of FMVSS No. 108 also discusses a visible pilot indicator for the vehicular hazard warning signal. The test condition requirement of S9.8.3 of the final rule comes from J945.

   S10 Headlighting System Requirements.

   The headlighting system requirements of S8 of the NPRM become S10 of the final rule.

   Paragraph S8.1 of the NPRM is now paragraph S10.1 (split for clarity) in the final rule. Guide commented that paragraphs S8.1.1 and S8.1.2 of the NPRM were redundant with the requirement, of paragraph S8.1, that the headlighting system conforms to one of the systems of Table II. We agree and eliminated paragraphs S8.1.1 and S8.1.2 from the final rule.

   We mentioned previously in the discussion of mounting location requirements that Guide commented that the content of sections 8.1.3 and 8.1.4 of the NPRM, dealing with headlamp beam mounting, was most appropriately located in the lamp mounting location section. We agree and have moved them intact to become paragraph S6.1.3.5 of the final rule.

   Paragraph S8.1.5, Headlamp adjustments, of the NPRM was relocated to be paragraphs S10.18.1.1 and S10.18.1.2 of the final rule.

   We adopted, in S10 of the final rule, the ASSN/AAM suggested standard format similar to that of the signal lamp and reflex reflector sections. Those standardized criteria that apply to headlamps with the appropriate

   [[Page 68251]]

   pointing statements or ``no requirement'' notations become paragraphs S10.3 through S10.12 of the final rule.

   The requirements for a sealed beam headlighting system, which were S9 of the NPRM, become paragraph S10.13 in the final rule. Paragraphs S9 and S9.1 of the NPRM have been relocated intact to become paragraphs S10.13 and S10.13.1 respectively in the final rule. The simultaneous aim requirements for type ``F'' sealed beam headlamps, which were paragraph S9.2 in the NPRM, become S10.13.2 in the final rule, the only revision being the revised reference for the applicable photometry procedure. Paragraph S9.3, Photometry, of the NPRM becomes paragraph S10.13.3 in the final rule, again with a revised reference to the photometry procedure. The physical tests requirements of paragraph S9.4 of the NPRM, which referenced Tables XXII and XXIII, become paragraph S10.13.4 (split for clarity) in the final rule, with updated references to the applicable test procedures and performance requirements in paragraph S14.

   The requirements for an integral beam headlighting system that were paragraph S10 of the NPRM become paragraph S10.14 in the final rule. Paragraphs S10 and S10.1 of the NPRM have been relocated to be paragraphs S10.14 and S10.14.1, respectively, in the final rule, with the only revision being the substitution of the term ``activated'' for the term ``mechanized'' used in the NPRM. Paragraphs S10.2, S10.3, and S10.4 of the NPRM have been relocated to become paragraphs S10.14.2 (split for clarity), S10.14.3, and S10.14.4 respectively in the final rule.

   AAM and Koito both commented that the language in paragraph S10.5 (repeated in paragraph S11.3) of the NPRM, stating that, ``An integral beam (replaceable bulb in paragraph S11.3) headlamp may incorporate replaceable light sources that are used for purposes other than headlighting'', could be interpreted to mean those ``replaceable light sources'' defined in S4 of the NPRM. This language came from paragraphs S7.4(i) and S7.5(j) of the current version of Standard No. 108. To alleviate concerns that this incorrect interpretation could be applied, we have revised the language of paragraph S10.5 (and paragraph S11.3) of the NPRM. Paragraph S10.14.5 (and paragraph S10.15.5) of the final rule now states, ``An integral beam (replaceable bulb in paragraph S10.15.5) headlamp may incorporate light sources that are used for purposes other than headlighting and are capable of being replaced.''

   Paragraph S10.6, Photometry, of the NPRM becomes paragraph S10.14.6 in the final rule, with a revised reference to the photometry procedure. The physical test requirements of paragraph S10.7 of the NPRM, which referenced Table XXII and Table XXIII, become paragraph S10.14.7 (split for clarity) in the final rule, with updated references to the applicable test procedures and performance requirements in paragraph S14.

   The requirements for a replaceable bulb headlighting system, which were paragraph S11 of the NPRM, become paragraph S10.15 in the final rule. Paragraph S11 of the NPRM has been relocated intact to be paragraph S10.15 in the final rule. Koito commented that the language of paragraph S11.1 of the NPRM stating, ``* * *must consist of the correct number of designated headlamp units shown for* * *'' did not clearly express the requirement. We agree and have revised this phrase to, ``* * *must consist of either two or four headlamps shown for* * *'' in paragraph S10.15.1 of the final rule.

   Paragraph S11.2 of the NPRM becomes paragraph S10.15.2 in the final rule. Paragraph S11.4 of the NPRM has the phrase ``* * *be designed to* * *'' inserted before the word ``conform'' when it becomes paragraph S10.15.3 of the final rule.

   Paragraph S11.5 of the NPRM is relocated to become paragraph S10.14.4.1 of the final rule. It is supplemented by a new paragraph S10.15.4.2 stating the exception from the requirements of paragraph S10.14.4.1 (that were contained in paragraphs S7.5(d)(3)(i)(A) and S7.5(d)(3)(ii)(A) of the current version of FMVSS No. 108), which was omitted from the NPRM, as noted in the comments of Guide and Koito.

   As previously mentioned, paragraph S11.3 of the NPRM was revised for clarity and becomes paragraph S10.15.5 in the final rule.

   Paragraph S11.6, Photometry, of the NPRM becomes paragraph S10.15.6 in the final rule, with a revised reference to the photometry procedure. The physical tests requirement of paragraph S11.7 of the NPRM, which referenced Table XXII and Table XXIII, becomes paragraph S10.15.7 (split for clarity) in the final rule, with updated references to the applicable test procedures and performance requirements in paragraph S14.

   The requirements for a combination headlighting system that were S12 of the NPRM become paragraph S10.16 in the final rule. Paragraphs S12 and S12.1 of the NPRM have been relocated to be paragraphs S10.16 and S10.16.1, respectively, in the final rule, with the only revision being the substitution of the term ``activated'' for the term ``mechanized'' used in the NPRM.

   Paragraph S12.2, Photometry, of the NPRM becomes paragraph S10.16.2 in the final rule, with a revised reference to the photometry procedure. The physical test requirements of paragraph S12.3 of the NPRM, which referenced Table XXII and Table XXIII, become paragraph S10.16.3 (split for clarity) in the final rule, with updated references to the applicable test procedures and performance requirements in paragraph S14.

   The requirements for a motorcycle headlighting system that were S13 of the NPRM become paragraph S10.17 in the final rule. Paragraphs S13.1, S13.1.1 (split for clarity), S13.1.2 (split for clarity), and S13.1.3 (split for clarity) of the NPRM are relocated intact to become paragraphs S10.17.1, S10.17.1.1, S10.17.1.2, and S10.17.1.3, respectively, of the final rule. Paragraph S13.4 of the NPRM becomes paragraph S10.17.2 of the final rule.

   Paragraph S13.2, Photometry, of the NPRM becomes paragraph S10.17.3 in the final rule, with a revised reference to the photometry procedure. The physical test requirements of paragraph S13.3 of the NPRM, which referenced Table XXII, become paragraph S10.17.5 in the final rule, with updated references to the applicable test procedures and performance requirements in paragraph S14.

   Paragraphs S13.5.1, Modulation, S13.5.2, Replacement modulators, S13.5.2.1, Replacement performance, and S13.5.2.2, Replacement instructions, of the NPRM are relocated intact to become paragraphs S10.17.5.1, S10.17.5.2, S10.17.5.2.1, and S10.17.5.2.2, respectively, in the final rule.

   Headlamp aimability requirements that were located in S14 in the NPRM have been relocated to paragraph S10.18 in the final rule with one exception and with very few revisions. The exception is proposed paragraph S14.2 dealing with equipment in front of a headlamp lens. The requirements of this section were moved to paragraph S6.2.6 in the Impairment section of the final rule.

   Paragraph S14.8.2 of the NPRM, which becomes paragraph S10.18.7.2 of the final rule, contains requirements for use of nonadjustable headlamp aiming device locating plates for five types of sealed beam headlamps. The language in the NPRM stated that these units should incorporate lens-mounted aiming pads specified in Figures a, b, c, d, or e of the NPRM. The figures referred to were intended to be placeholders in

   [[Page 68252]]

   a draft version of the NPRM. The NPRM should have stated that, ``* * * incorporate lens-mounted aiming pads as specified for those units in Appendix C of part 564 of this chapter,'' which is incorporated in paragraph S10.18.7.2 of the final rule.

   Koito requested that an alternative measurement distance of 25 m be permitted for the measurement of the cutoff parameter for a visually/ optically aimed headlamp. Paragraph S14.10.1.5 of the NPRM, based upon the April 6, 2000 letter of interpretation to Mr. Spingler,\25\ required the measurement distance to be 10 m. One of the objectives of the rewrite of Standard No. 108 is to improve the clarity of the document without changing the substance of the existing requirements. The referenced letter of interpretation states a specific measurement distance without alternatives. Therefore, Koito's request would be a substantive change beyond the scope of the rewrite and paragraph S10.18.9.1.5 of the final rule duplicates the requirement from the NPRM.

   S11 Replaceable Light Source Requirements

   Paragraph S15 of the NPRM, Replaceable light source requirements, is relocated to S11 in the final rule. Paragraphs S15 and S15.1 from the NPRM become paragraphs S11 and S11.1, respectively, in the final rule. Paragraph S15.4, Ballast markings, of the NPRM becomes paragraph S11.2 in the final rule and paragraph S15.5, Gas discharge laboratory life, becomes paragraph S11.3. Paragraph S15.6 of the NPRM, containing requirements for physical tests of replaceable light sources, is split into paragraphs S11.4.1 and S11.4.2 in the final rule. Paragraph S11.4.1 references the deflection test and pressure test applicable to replaceable light sources, which were part of Table XXIII in the NPRM and have been relocated to paragraph S14.7 in the final rule. Paragraph S11.4.2 references a restated power and flux measurement test that is described in paragraph S14.7.3 of the final rule, noting that the performance requirements for this test do not reside in the main text of Standard No. 108, but in the applicable appendix of part 564 of this chapter.

   The NPRM contained paragraphs S15.2 and S15.3, both titled Power and flux measurement, which essentially described the same test of replaceable light sources. Recognizing that they were test procedures and striving to advance the objectives of the rewrite, we consolidated the procedures of paragraphs S15.2 and 15.3 into a single procedure, without revising or modifying the requirements, and relocated it to paragraph S14.7.3 of the final rule. S12 Headlamp Concealment Device Requirements

   The headlamp concealment device requirements of S16 of the NPRM are relocated intact to S12 of the final rule. S13 Replaceable Headlamp Lens Requirements

   The replaceable headlamp lens requirements of paragraph S18 of the NPRM are relocated intact (split for clarity) to paragraph S13 of the final rule. S14 Physical and Photometry Test Procedures and Performance Requirements

   As previously mentioned, ASSN/AAM and Grote commented that tables containing significant amounts of text, such as the test requirements in Tables XXI, XXII, and XXIII of the NPRM, are difficult to use because of lengthy passages that contain several sentences and express several unique test conditions or requirements. We agree with these comments. In the final rule, we have moved virtually all test procedures and their associated performance requirements to S14.

   General test procedures and performance requirements that were located in paragraph S6.8 of the NPRM have been placed in paragraph S14.1 of the final rule. Similarly, the photometric test procedures of paragraph S6.8 of the NPRM are now paragraph S14.2 of the final rule.

   Part of Table XXII of the NPRM, the out of focus test applicable to motorcycle headlamps designed to conform to paragraph S10.17(b), becomes paragraph S14.3 in the final rule. The color test and plastic optical materials test of Table XXII become paragraph S14.4 in the final rule. The remaining tests of Table XXII, the vibration test, moisture test, dust test, and corrosion test, become paragraph S14.5 in the final rule.

   All tests applicable to complete headlamps included in Table XXIII of the NPRM have been relocated to paragraph S14.6 of the final rule. The tests in Table XXIII of the NPRM related to replaceable light sources become paragraph S14.7 in the final rule. Tests in Table XXIII of the NPRM that apply to vehicle headlamp aiming devices (VHAD) were relocated to be paragraph S14.8 in the final rule. Also, the tests applicable to associated equipment that were located in Table XXI of the NPRM become paragraph S14.9 in the final rule.

   S6.8.1 of the NPRM, stating that lamps, reflective devices, and associated equipment regulated by Standard No. 108 be designed to conform to applicable physical test requirements, becomes paragraph S14.1.1 of the final rule. This is followed by proposed paragraphs S6.8.4 and S.8.4.1 of the NPRM, applicable to plastic optical materials, which become paragraphs S14.1.2 and S14.1.3, respectively, in the final rule. Bayer had asked that the word ``reflex'' be placed before the word ``reflector'' in paragraph S14.1.2 but we prefer to keep the language faithful to paragraph S5.1.2 of the current version of Standard No. 108. Paragraph S14.1.4, Samples, of the final rule is paragraph S6.8.2 (split for clarity) of the NPRM, except for the sentence ``A mounting bracket with a sample headlamp installed must not have a resonant frequency in the 10-55 Hz. range'' which was relocated to paragraph S14.6.8.1 in the final rule because of its specific applicability to the vibration test for headlamps. Paragraph S6.8.3 of the NPRM is now paragraph S14.1.5 of the final rule.

   Paragraph S6.8.5 of the NPRM becomes paragraph S14.2, Photometric test procedures, in the final rule. Paragraph S6.8.5.1 was split for clarity and becomes paragraph S14.2.1 in the final rule. Nissan commented that the measurement distance requirements in paragraph S6.8.5.1 were confusing because they mentioned license plate lamps and headlamps. We agree and have revised the text of paragraph S14.2.1.3 of the final rule to expressly state the required distance for all lamps that paragraph S14.2.1 applies to. Nissan also noted that proposed paragraph S6.8.5.1 contained a requirement for photometric intensity between test points that was duplicated in several photometry requirements tables as a footnote. We eliminated this language from paragraph S14.2.1 of the final rule, deciding that the individual requirements tables were the appropriate location for the intensity between test point requirements.

   Paragraph S6.8.5.1.1 of the NPRM becomes, in its entirety, paragraph S14.2.1.4 (split for clarity) of the final rule. Paragraph S6.8.5.1.2, detailing requirements for photometry of multiple compartment lamps and multiple lamps, becomes paragraph S14.2.1.5 in the final rule. We adopted the suggestion of Koito to specifically indicate the type of lamps to which this section applies.

   [[Page 68253]]

   Paragraph S6.8.5.2 of the NPRM becomes paragraph S14.2.1.6 (split for clarity) in the final rule. Paragraph S14.2.1.6.2 was added to this section at the suggestion of Calcoast, which observed that the NPRM had not included the content of Footnotes 2 and 3, which follow Table IV, of the current version of FMVSS No. 108. The last sentence of paragraph S6.8.2, which specifically addressed samples for the color test of reflex reflectors, was moved to be paragraph S14.4.1.1 of the final rule.

   Paragraph S6.8.5.3, License plate lamp photometry, of the NPRM becomes paragraph S14.2.2 in the final rule. Paragraphs S6.8.5.3.1 and S6.8.5.3.2 of the NPRM become paragraphs S14.2.2.1 and S14.2.2.2, respectively, in the final rule. Nissan observed that the language of paragraph S6.8.5.3.2 was awkward and suggested a revision that did not change the substance of the requirement. We adopted Nissan's suggestion in paragraph S14.2.2.2. We also added paragraph S14.2.2.3 to the final rule to clarify that the bulb requirements of paragraph S14.2.1.6 also apply to license plate lamp photometry.

   Proposed paragraph S6.8.5.4, stating requirements for reflex reflector and retroreflective sheeting photometry, becomes paragraph S14.2.3 in the final rule. For clarity, paragraph S6.8.5.4 of the NPRM has been split into paragraphs S14.2.3.1 through S14.2.3.6 and paragraph S6.8.5.4.1 has been split into paragraphs S14.2.3.7.1 through S14.2.3.8.2 in the final rule. Likewise, paragraph S6.8.5.4.1.1 in the NPRM becomes paragraph S14.2.3.8.3.1 in the final rule.

   3M commented that the language of paragraph S6.8.5.4.1 of the NPRM, which is paragraph S14.2.3.7 of the final rule, did not allow a complete photometric evaluation of retroreflective sheeting because a presentation angle was not specified. 3M's premise was that the test method of the current version of FMVSS No. 108 relies on conventions regarding orientation and presentation that are part of ASTM E 810, Standard Test Method for Coefficient of Retroreflection of Retroreflective Sheeting Utilizing the Coplaner Geometry, which is referenced by ASTM D 4956, Standard Specification for Retroreflective Sheeting for Traffic Control, a document 3M contends is no longer referenced in the NPRM. This contention is incorrect. The reference to ASTM D 4956, from paragraph S5.7.1.2 of the current version of FMVSS No. 108, is replicated in paragraph S7.12.1 of the NPRM and finally by paragraph S8.2.1.2 of the final rule, with consistent language throughout. Since the connection to ASTM E 810 still exists, we see no reason to modify the final rule as 3M suggested.

   Nissan suggested that the language concerning the mounting of a reflex test sample for photometry, which becomes paragraph S14.2.3.1 of the final rule, did not allow for a test chamber which does not provide a linear 100 foot test distance, but rather was arranged in a non- horizontal orientation. We do not agree and, therefore, have not changed the text from the NPRM to the final rule. The procedure of paragraph S14.2.3.1 is faithful to the language of paragraph 3.1.7 of SAE J594f, Reflex Reflectors, January 1977, incorporated by reference in the current version of FMVSS 108.

   The reflex reflector photometry test, like all tests in Standard No. 108, describes a procedure that NHTSA would use to test a reflex reflector for purposes of compliance. It also describes the performance requirements that the reflector must be designed to conform to, when tested according to the procedure. If a manufacturer chooses to use a procedure that differs with that described in FMVSS No. 108 as its basis of compliance, or to establish a basis of compliance that does not rely on an actual test, it is free to do so. However, the manufacturer must exercise due care in designing its product to conform to the performance requirements of all applicable tests in Standard No. 108 when tested according to the procedures stated in the standard.

   Paragraph S6.8.5.5, Daytime running lamp (DRL) photometry measurements, of the NPRM becomes paragraph S14.2.4 (split for clarity) of the final rule. Paragraph S14.2.4.3 was added to the final rule to clarify that the bulb requirements of paragraph S14.2.1.6 also apply to DRL photometry.

   Nissan expressed some confusion regarding how a dedicated DRL, without any equipment that alters or conditions the voltage, should have power applied to it for photometric testing as stated in paragraph S14.2.4. We are unable to answer this question as part of the rewrite process and note Nissan can request an interpretation for this specific situation.

   Paragraph S6.8.5.6 of the NPRM, covering photometry measurements of headlamps, becomes paragraph S14.2.5 in the final rule. Some rearrangement of content and splitting of sections for clarity was incorporated into the final rule. Specifically, paragraph S14.2.5.1 of the final rule contains the first sentence of paragraph S6.8.5.6 of the NPRM, paragraph S14.2.5.2 contains the last sentence of paragraph S6.8.5.6.5, paragraph S14.2.5.3 contains the last sentence of paragraph S6.8.5.6, paragraph S14.2.5.4 duplicates paragraph S6.8.5.6.1, paragraph S14.2.5.5 duplicates paragraph S6.8.5.6.2, paragraphs S14.2.5.5.1 and S14.2.5.5.2 duplicate paragraphs S6.8.5.6.2(a) and S6.8.5.6.2(b) respectively, paragraph S14.2.5.5.3 (split for clarity) duplicates paragraph S6.8.5.6.2(c), paragraph S14.2.5.5.4 duplicates paragraph S6.8.5.6.2(d), paragraph S14.2.5.5.5 (split for clarity) duplicates paragraph S6.8.5.6.2(e), paragraph S14.2.5.5.6 (split for clarity) duplicates paragraph S6.8.5.6.2(f), paragraph S14.2.5.5.7 (split for clarity) duplicates paragraph S6.8.5.6.2(g), paragraph S14.2.5.5.8 duplicates paragraph S6.8.5.6.2(i), and paragraph S14.2.5.5.9 duplicates paragraph S6.8.5.6.2(j). Paragraph S6.8.5.6.2 of the NPRM becomes paragraph S14.2.5.6 of the final rule, paragraph S6.8.5.6.4 becomes paragraph S14.2.5.7 (split for clarity), paragraph S6.8.5.6.5 (less the last sentence) becomes paragraph S14.2.5.8 (split for clarity), and paragraph S6.8.5.6.6 becomes paragraph S14.2.5.9. Guide commented that paragraph S6.8.5.6.2(h) of the NPRM described photometry measurement for moveable reflector headlamps rather than an aiming procedure and did not belong where it was located. We agree and have designated this provision as paragraph S14.2.5.10 in the final rule.

   AAM and Honda objected to the word ``specified'' which appeared before ``position relative to the * * *'' in the NPRM. We omitted ``specified'' in the final rule to be faithful to paragraph S7.8.2.2(b) of the current version of FMVSS No. 108. We also added a horizontal range exclusion for visually/optically aimed moveable reflector headlamps with a fixed horizontal aim to be faithful to paragraph S7.8.2.2(d) of the current version of FMVSS No. 108, as noted in the comments of Nissan.

   Paragraph S14.3 of the final rule contains the out of focus test that was part of Table XXII of the NPRM. This test only applies to motorcycle headlamps that are designed to conform to paragraph S10.17(b) of the final rule. AAM identified two typographical errors in the out of focus test procedure where there were no periods after the abbreviations ``in''. Our practice is to not include a period after such abbreviations, so the text identified by AAM is correct although in several other instances we did include a period after such an abbreviation. In the final rule we have removed periods after all such abbreviations, except in those situations where other grammatical

   [[Page 68254]]

   requirements, such as the end of a sentence, require a period.

   Paragraph S14.4 of the final rule, General test procedures and performance requirements, contains the color test and plastic optical materials test, along with applicable requirements, from Table XXII of the NPRM. In both tests, the text as stated in the NPRM has been split for clarity in the final rule.

   AAM noted that the Scope of SAE J578c, Color Specification for Electric Signal Lighting Devices, February 1977, contains limitations on the application of this standard that may be important to lighting manufacturers. This portion of SAE J578c was inadvertently left out of Table XXII in the NPRM. In the final rule, we have added it as paragraph S14.4.1. This section will now read, ``The requirement applies to the overall effective color of light emitted by the device and not to the color of the light from a small area of the lens. It does not apply to any pilot, indicator, or tell-tale lights. The color of the sample device * * *''

   Paragraph S14.4.1.1 of the final rule, detailing alternatives for samples used in the color test of reflex reflectors, originated from the last sentence of paragraph S6.8.2 of the NPRM.

   Koito, 3M, and Honda commented that the language of the performance requirement for the color test for the color yellow using the visual evaluation method omitted a key word. In the NPRM, the requirement is stated as, ``Yellow (Amber) is acceptable if it is less saturated (paler), greener, or redder than the limit standard.'' The revised text in the final rule states, ``Yellow (Amber) is not acceptable if it is less saturated (paler), greener, or redder than the limit standard''

   [emphasis added] .

   AAM commented that the color restricted blue should be included in the final rule because it appears in SAE J578c. We know of no requirements in Standard No. 108 for the light from a lamp or the color of a lens material to be restricted blue. We also observed that there are also no such requirements for the colors green or blue. Therefore, we have not only decided against adding requirements for restricted blue but also have removed the requirements for the colors blue and green for both the visual evaluation method and the tristimulus evaluation method of the color test of paragraph S14.4.1 in the final rule.

   AAM commented that Section 3.2, Tristimulus Method, from SAE J578c is not stated in its entirety in the procedure column of the color test of proposed Table XXII. We have reviewed SAE J578c and the text of the Tristimulus Method procedure from proposed Table XXII. We do not find that the text of proposed Table XXII omitted any substantive portion of SAE J578c that describes how the test is performed. In the absence of any specific explanation of its comments by AAM, we are not revising the Tristimulus Method section, now located in paragraph S14.4.1.4 of the final rule.

   Paragraph S14.4.2 of the final rule contains the plastic optical materials tests from Table XXII of the NPRM. Atlas, Bayer, Grote, and AAM commented that the performance requirement for headlamp lens materials after the outdoor exposure test portion of the plastic optical materials tests in Table XXII of the NPRM was not identical to that stated in Section 4.2.3 of SAE J576 JUL91. The language of the NPRM stated that the requirement was no haze greater than 0% when measured by ASTM D 1033 (1992). SAE J576 JUL91 states the requirement as ``shall show no deterioration.''

   Koito noted that while the measurement method of ASTM D 1033 (1992) was required for evaluation of the post exposure haze of other materials, it was not required for the evaluation of headlamps. Koito also stated that the post exposure performance requirements for luminous transmittance and color required by SAE J576 at Sections 4.2.1 and 4.2.2 are missing from the NPRM. We agree with these comments and have revised the plastic optical materials test outdoor exposure test portion performance requirements accordingly. Specifically, the performance requirement section for headlamp lenses, now paragraph S14.4.2.2.4.2 of the final rule, no longer requires evaluation by ASTM D 1033 (1992) and states, ``After completion of the outdoor exposure test, materials used for headlamp lenses must show no deterioration.'' The performance requirement section for luminous transmittance, now paragraph S14.4.2.2.4.4, states, ``After completion of the outdoor exposure test, all materials, when compared with the unexposed control samples, must not have their luminous transmittance changed by more than 25% when tested in accordance with ASTM E 308-66 (1973) using CIE Illuminant A (2856K).'' The performance requirement section for color, now paragraph S14.4.2.2.4.5, states, ``After completion of the outdoor exposure test, all materials must conform to the color test of this standard in the range of thickness stated by the material manufacturer.''

   Bayer stated that specifying 2.3 mm thick test samples for the plastic optical materials tests represents a change from the current version of FMVSS No. 108 and may increase the testing burden of the industry. We do not believe that specifying 2.3 mm thick samples is a change from current requirements. SAE J576 JUL91 does only suggest 2.3 mm samples, paragraph S5.2.1 of the current version of FMVSS No. 108 (and paragraph S5.1 of the NPRM) states that, ``The words `It is recommended that', `recommendations', or `should be' appearing in any SAE Standard or Recommended Practice referenced or subreferenced by this standard shall be read as setting forth mandatory requirements * * *'' We consider the term ``suggest'' to have a similar meaning as the term ``should be'' and have therefore included 2.3 mm as one of the sample thicknesses used for the plastic optical material test. We believe there is value in specifying sample thickness. The inclusion of the 2.3 mm sample thickness also serves to alert regulated parties that should the agency choose to perform a compliance test, it will perform the test on this sample thickness.

   AAM suggested eliminating the notation concerning test samples having 32 sq cm of exposed area from the Procedure column of Table XXII of the NPRM and allowing it to remain in the Samples column of the outdoor exposure test portion of the plastic optical materials tests. We do not agree with this suggestion. The area requirement is important in both the preparation of the samples and their mounting orientation for the exposure test. An area specification is appropriate in both places and is included in both paragraph S14.4.2.1.2 and paragraph S14.4.2.2.3.1 of the final rule.

   The NPRM omitted the third sentence of SAE J576 JUL91 Section 3.3.2 requiring that samples be mounted in the open with a minimum 30 cm (11.8 in) separation from their background. This has been corrected in the final rule by including the separation requirement in paragraph S14.4.2.2.3.1.

   AAM suggested that content of the Samples column of Table XXII of the NPRM for the outdoor exposure test portion of the plastic optical material tests be repeated for the heat test portion separately. We agree that this would add clarity. We have revised the heat test portion of the plastic optical materials tests to appear as a test separate from the outdoor exposure test and have placed content specific to the heat test into paragraph S14.4.2.3 of the final rule.

   Paragraph S14.5 of the final rule, Signal lamp and reflective device test procedures and performance requirements, contains the vibration,

   [[Page 68255]]

   moisture, dust, and corrosion tests that were located in Table XXII of the NPRM.

   As previously mentioned, the references in the NPRM to SAE J577, Vibration Test Machine, April 1964, have been eliminated in the final rule with the incorporation of the drawing and mechanical details of the vibration machine as Figure 21. The reference in the vibration test procedure to SAE J577 has been revised to Figure 21 in paragraph S14.5.1.1 of the final rule.

   AAM, Honda, and Guide commented about the inadvertent omission of the phrase ``one hour'' from the moisture test procedure of Table XXII of the NPRM. This is corrected in the final rule where paragraph S14.5.2.1, second sentence, states, ``* * * followed by a one hour drain period * * *''

   We have decided that the first sentence of the moisture test performance requirements of the NPRM stating, ``After completion of the moisture test * * *'' is more appropriately part of the test procedure. Therefore, we are relocating it to be the last sentence of paragraph S14.5.2.1 of the final rule.

   Calcoast commented that the moisture test performance requirement for a sealed reflex unit stated in SAE J594f, January 1977, at Section 3.1.4 is ``any visible moisture constitutes a failure.'' We agree and have revised the moisture test performance requirements of paragraph S14.5.2.2 in the final rule to state ``Accumulation of moisture in excess of 2 cc, or any visible moisture in a sealed reflex unit, must constitute a failure.''

   AAM noted that the dust test of Table XXII of the NPRM is not required to be performed on sealed units per SAE J575d, August 1967, Section G, and SAE J575e, August 1970, Section G. We agree and in the final rule paragraph S14.5.3.1, Samples states, ``A sealed unit is not required to meet the requirements of this test.'' We also decided that the first sentence of the performance requirements of the dust test stating, ``After completion of the dust test the exterior surface of the device must be cleaned'' was part of the test procedure rather than a performance requirement so that sentence was moved to paragraph S14.5.3.2 in the final rule.

   Paragraph S14.6 of the final rule, Headlamp physical test procedures and performance requirements, consists of all headlamp test procedures from Table XXIII of the NPRM, except for those that apply specifically to replaceable light sources or vehicle headlamp aiming devices (VHAD). Several of the tests that become paragraph S14.6 had significant portions of their text split for clarity as part of their relocation from Table XXIII of the NPRM to paragraph S14.6 of the final rule. These tests include: (1) Abrasion test, (2) chemical resistance test, (3) corrosion connector test, (4) dust test, (5) temperature cycle test, (6) internal heat test, (7) humidity test, (8) sealing test, (9) chemical resistance of reflectors of replaceable lens headlamps, (10) corrosion resistance of reflectors of replaceable lens headlamps, (11) torque deflection test, and (12) both aiming adjustment tests.

   Honda commented that the pad cycling rate of the abrasion test procedure of Table XXIII of the NPRM contained typographical errors. We agree and have revised the text in paragraph S14.6.1.1.3 of the final rule from ``11 cycles at 10 cm per second * * *'' to the correct language from the current version of FMVSS No. 108 paragraph S8.2(b) which is, ``* * * 11 cycles at 4 0.8 in (10 2 cm) per second * * *.''

   AAM stated the requirement that the same sample headlamp be used in both the temperature cycle test and the internal heat test was not supported in the current version of FMVSS No. 108. We disagree. The current version of Standard No. 108 states, concerning integral beam headlamps at paragraph S7.4(h)(5), ``The headlamp shall meet the requirements of subparagraph (i) and then those of subparagraph (ii)

   [emphasis added] . Subparagraph (i) describes a temperature cycle test in accordance with paragraph S8.6.1 and subparagraph (ii) describes an internal heat test in accordance with paragraph S8.6.2. Paragraph S7.5(h)(i) requires replaceable bulb headlamps to meet the same physical tests in paragraphs 7.4(g) and S7.4(h) that are required of an integral beam headlamp. Thus, there is a very clear requirement that a single headlamp sample be used, in sequence, in the temperature cycle test and then the internal heat test.

   Guide and VS commented that the humidity test of Table XXIII of the NPRM incorrectly included a performance requirement of post-test photometry. We agree, and the post-test photometry provision has been removed from the humidity test, which is contained in paragraph S14.6.7.2 of the final rule.

   Honda and AAM observed a typographical error in the tolerance for air flow uniformity in paragraph (d) of the humidity test procedure. The text of the NPRM states, ``* * * each grid point is 10% of the average * * *'' while the corrected text of paragraph S14.6.7.1.6 of the final rule states, ``* * * each grid point is 10% of the average* * *'' which is faithful to paragraph S8.7(d) of the current version of FMVSS No. 108.

   As we mentioned in the discussion of paragraph S14.5, the references in the NPRM to SAE J577, Vibration Test Machine, April 1964, have been eliminated in the final rule with the incorporation of the drawing and mechanical details of the machine as Figure 21. The reference in the vibration test procedure of Table XXIII of the NPRM to SAE J577 has been revised to Figure 21 in the final rule.

   Nissan observed that the applicability of the chemical resistance of reflectors of replaceable lens headlamps test and the corrosion resistance of reflectors of replaceable lens headlamps test did not include integral beam headlamps, as required by paragraph S5.8.11 of the current version of FMVSS No. 108. Its comment is correct and paragraph S10.14.7.6 of the final rule correctly states the requirement for these two tests.

   Koito and Nissan questioned whether the inward force test of Table XXIII applied to headlamps other than sealed beams, particularly those headlamps that utilize a VHAD or are visually/optically aimed. This requirement comes from paragraph S7.8.5.1(b) of the current version of FMVSS No. 108. That paragraph states, ``when a headlamp is installed on a motor vehicle, its aim in any direction shall not change by more than 0.30 degree nor shall the lamp recede more than 0.1 in (2.5 mm) after being subjected to an inward force of 50 pounds (222 newtons) applied evenly to the lens parallel to the mechanical axis.'' There is no distinction in this paragraph to any particular type of headlamp, so it must be applied to all headlamps.

   Nissan commented that the performance requirements of the aiming adjustment test (laboratory) were ``difficult to read'' as presented but did not explain the difficulties or suggest alternative language. In the final rule, we have split the performance requirements of this test into paragraphs S14.6.17.2.1, S14.6.17.2.2, and S14.6.17.2.3, which we believe will improve clarity.

   Paragraph S14.7 of the final rule, Replaceable light source physical test procedures and performance requirements, consists of the deflection test for replaceable light sources and the pressure test for replaceable light sources from Table XXIII of the NPRM, along with a replaceable light source power and flux measurement procedure. The text of all of these items has been split for clarity in the final rule. There were no comments submitted that impacted the substance of these

   [[Page 68256]]

   procedures and requirements. However as mentioned in the discussion of paragraph S11, the NPRM contained paragraphs S15.2 and S15.3, both titled Power and flux measurement, that essentially described the same test of replaceable light sources. We consolidated the procedures of paragraphs S15.2 and S15.3 into a single procedure, without revising or modifying the requirements, and relocated it to paragraph S14.7.3 of the final rule.

   Paragraph S14.8 of the final rule, Vehicle headlamp aiming device (VHAD) physical test procedures and performance requirements, consists of the six VHAD tests that were part of Table XXIII of the NPRM. There were no comments submitted that impacted the substance of these procedures and requirements.

   Paragraph S14.9 of the final rule, Associated equipment physical test procedures and performance requirements, consists of the tests contained in Table XXI of the NPRM. These test procedures and performance requirements, as written in Table XXI of the NPRM, were in block paragraph form. As we have done in several places throughout the final rule, we have split some of these longer paragraphs into several smaller sections, which are grouped according to similar content, in an effort to improve clarity.

   One of the goals of the FMVSS No. 108 rewrite was to remove outdated requirements from the document. The physical test requirements for associated equipment presented an opportunity to pursue this goal. The applicable SAE documents incorporated by reference in FMVSS No. 108 were adopted between 1964 and 1969 and several of them contained specifications for both vehicles with a nominal 12 volt electrical system as well as those with a nominal 6 volt electrical system. Believing that few, if any, vehicles manufactured after the effective date of FMVSS No. 108 have been equipped with a nominal 6 volt electrical system, we deleted references to that voltage in the proposal.

   In its comments, AAM requested that we restore the nominal 6 volt requirements to the physical test requirements for associated equipment. Presumably, this comment was based upon the knowledge that one of its constituent organizations was producing a 6 volt device for a regulated vehicle or had plans to do so. While we continue to believe that those requirements are not currently being used by any regulated party, we do not want to eliminate a compliance option that has value. Therefore, we have restored the applicable language from the SAE documents \26\ incorporated by reference in the current version of FMVSS No. 108 for testing devices used in a nominal 6 volt electrical system. The restoration of nominal 6 volt requirements necessitated revisions in the following portions of paragraph S14.9 of the final rule: (1) S14.9.1 turn signal operating unit durability test procedure, (2) S14.9.2.2 vehicular hazard warning signal operating unit durability performance requirements, and (3) S14.9.3 turn signal flasher and vehicular hazard warning signal flasher test procedure and performance requirements.

   \26\ SAE J589, Turn Signal Operating Units, April 1964; SAE J910, Vehicular Hazard Warning Signal Operating Unit, January 1966; SAE J945, Vehicular Hazard Warning Signal Flasher, February 1966; SAE J590b, Automotive Turn Signal Flashers, October 1965; and SAE J823b, Flasher Test Equipment, April 1968.

   AAM and Honda commented that the reference in the turn signal operating unit durability test procedure in Table XXI of the NPRM incorrectly stated the ripple voltage tolerance of the power supply. We agree and have revised the language of that procedure in the final rule. The text `` * * * ripple voltage of less than 5% * * * was changed to `` * * * ripple voltage of not more than 5% * * *.''

   The turn signal flasher and vehicular hazard warning signal flasher both maintained their reference to SAE J823b, Flasher Test Equipment, April 1968, in the NPRM. As previously mentioned, this document was eliminated from the final rule by incorporating its content directly into Standard No. 108. This was accomplished in the final rule by creating Figure 22, Flasher Standard Test Circuit, for the circuit diagram of Figure 1 of SAE J823b, and also by listing the test setup requirements of Sections 3 through 9 of SAE J823b in paragraph S14.9.3 of the final rule as well as the power supply specifications for testing performance requirements and those specifications for testing durability requirements that were Section 10 of SAE J823b into paragraph S14.9.3.2 of the final rule.

   Koito commented on the load requirements (from paragraph S5.1.1.19 of the current version of FMVSS No. 108) for variable load turn signal flashers for the turn signal flasher starting time test and the flash rate and percent current ``on'' time test. In the proposal, this information was located parenthetically after the notation ``Starting time test'' and ``Flash rate and percent current ``on'' time test''. We agree with Koito that this is not the optimum location for this provision, and have inserted it into the applicable test procedure in the final rule. Where those proposed procedures stated ``* * * with the design load connected * * *'' the text of the final rule now states ``* * * with the design load (variable load flashers are tested with their minimum and their maximum design load) connected * * *.''

   Koito and AAM observed that load specifications stated in the procedure for the turn signal flasher voltage drop test and durability test procedures did not clearly replicate the requirements from paragraph S5.1.1.19 of the current version of FMVSS No. 108, and SAE J590b, October 1965, Section 2. We have revised the language of those procedures in the final rule to clarify the load specifications. The proposed procedures stated ``* * * with the maximum design load connected * * *'' which has changed in the final rule to state `` * * * with the design load (variable load flashers are tested with their maximum design load) connected * * *.''

   Honda observed that the durability test performance requirements for the vehicular hazard warning signal flasher did not include the notation from SAE J945, February 1966, Section 7, requiring the post durability test to incorporate pilot lamps as part of the maximum design load. We agree and have revised the language of the performance requirements in paragraph S14.9.3.10.3 of the final rule from `` * * * maximum design load at an ambient * * * '' to ``maximum design load, including pilot lamps as specified by the manufacturer, at an ambient* * *.''

   Honda, AAM, and Koito all commented that the column headings for the semiautomatic headlamp beam switching device sensitivity test performance requirements were incorrect. We agree and have revised them in paragraph S14.9.3.11.2.3.1 of the final rule. They now read from left to right: Test position (degrees) [above the two columns of lateral and vertical test points], Dim (cd at 100 ft), and Hold (cd at 100 ft).

   Honda observed that the maximum dim sensitivity at test point H-5R was incorrectly stated in the NPRM as 100 (cd at 100 feet). The correct value is 150 (cd at 100 feet) as shown in Table 1 of SAE J565b, February 1969. We incorporated this revision in the final rule.

   Koito also commented that the semiautomatic headlamp beam switching device voltage regulation test procedure incorrectly refers to ``dim'' sensitivity in the NPRM. The correct notation is ``hold'' sensitivity and that is

   [[Page 68257]]

   what appears in paragraph S14.9.3.11.3.1.2 of the final rule.

   AAM commented that the language of the semiautomatic headlamp beam switching device warmup test performance requirement of the NPRM was not faithful to SAE J565b, February 1969, Section 4.5. We have revised that language in paragraph S14.9.3.11.5.2 of the final rule to be identical to the first sentence of Section 4.5, specifically, ``If the warmup time of the device exceeds 10 seconds, it must maintain the headlamps on lower beam during warmup.'' Tables Table I-a Portion of Proposed Table I

   As mentioned previously, we have decided to split Table I of the NPRM into three sections. Table I-a lists lamp and reflective device requirements for passenger cars, multipurpose passenger vehicles, trucks, and buses of all widths. Where we refer to comments about the content of Table I-a, it indicates that those comments were submitted about the content of the portion of Table I of the NPRM now contained in Table I-a of the final rule.

   Based on comments submitted to the docket regarding our proposal, we have decided to make several revisions to Table I-a. One of these revisions was the inclusion of the abbreviation ``MPV'' in parenthesis after the term ``Multipurpose Passenger Vehicle'' in the title of Table I-a. We have subsequently used this abbreviation several times in this document.

   Guide commented that the reference in Table I for the number and color of headlamps does not directly state a number but instead makes an additional reference to Table II. We do not find this method difficult or complex, it somewhat duplicates the method of the current version of FMVSS No. 108. Sub-referencing is necessary because the number of headlamps actually used depends on the headlighting system chosen. We clarified the language of Table I-a for the number of upper beam and lower beam headlamps from `` * * * type and number * * * '' to `` * * * headlighting system * * * '' to more precisely describe this sub reference.

   AAM and Koito commented about the inclusion of the phrase `` * * * equal to or wider than the upper beam headlamps'' in the mounting location description for lower beam headlamps along with the corresponding phrase `` * * * equal to or narrower than the lower beam headlamps'' in the mounting location description for the upper beam headlamps. They, along with Honda, which commented about the same language in Table I relating to motorcycle headlamps, believe that this phrase is inconsistent with the current FMVSS No. 108 requirement. We agree that it does not fully describe the relationship required between upper and lower beam headlamps. We removed this language from Tables I- a and I-c of the final rule and incorporated headlamp beam spacing requirements in paragraph S6.1.3.5.

   AAM commented that the activation requirement for turn signal lamps stating, ``Current 108 paragraph S5.1.1.19 references SAE J590b * * * in which Figure 1 combines flash rate and percent current ``on'' time. This figure appears as Figure 2 in Rewrite 108. There is no reference to percent current ``on'' time in Rewrite 108 Table I. We are unable to find a reference to Rewrite Figure 108 anywhere within the Rewrite 108 text.'' The reference to NPRM Figure 2 is contained in Table XXI which details the performance of turn signal (and vehicular hazard warning signal) flashers, specifically in the performance requirements for the Flash Rate and Percent Current ``On'' Time Test. We agree that including the rate of 60 to 120 flashes per minute in Table I is a detail that is not needed. The flash rate will be determined by the choice of flasher and its performance when subjected to the test of paragraph S14.9.3. Therefore, we are revising the Device Activation requirement for turn signal lamps in Table I-a (and the corresponding requirement in Table I-b for trailers and in Table I-c for motorcycles) to read, ``Flash when the turn signal flasher is actuated by the turn signal operating unit.'' This statement more accurately describes the process by which the turn signal lamps are caused to flash.

   AAM, Honda, and Koito commented about the activation requirements for taillamps, side marker lamps, and license plate lamps with respect to their required activation when the parking lamps are activated. AAM contended that the NPRM does not clearly state that the taillamps, side marker lamps, and license plate lamps are required to be activated when the parking lamps are activated only on vehicles less than 2032 mm in overall width. To clarify those requirements, we revised the language of the activation requirement from * * * ``Must be activated when the headlamps are activated in a steady burning state or the parking lamps are activated (not a requirement for vehicles 2032 mm or more in overall width)``, to * * * ``Must be activated when the headlamps are activated in a steady burning state or the parking lamps on passenger cars and MPVs, trucks, and buses less than 80 inches in overall width are activated.'' This revision was made to the Device Activation requirements for taillamps, side marker lamps, intermediate side marker lamps, and license plate lamps in Table I-a.

   AAM also commented that the activation requirement for a stop lamp optically combined with a turn signal lamp was not stated in Table I using the language from SAE J586 FEB84, at Section 5.4.2 and SAE J1398 MAY85, also at Section 5.4.2. One of the stated intentions of the rewrite is to clarify requirements without making substantive changes to them. Although we were satisfied with the language of the NPRM in this situation, we revised the language to be faithful to the original SAE language. We replaced the third sentence of the Device Activation requirement for stop lamps in Table I-a with ``When a stop signal is optically combined with the turn signal, the circuit must be such that the stop signal cannot be turned on if the turn signal is flashing.'' Identical revisions have been made in Table I-b for trailers and Table I-c for motorcycles.

   We have corrected an omission in Table I-a with respect to the requirements applicable to a truck tractor. The current version of FMVSS No. 108 excludes, in paragraph S5.1.1.2, a truck tractor from being required to be equipped with any rear side marker devices, rear clearance lamps, and rear identification lamps. The NPRM included this exclusion for rear side marker lamps, rear clearance lamps, and rear identification lamps but failed to include the notation for rear side reflex reflectors. This has been corrected in the final rule.

   TTMA stated in its comments that the partial photometric output exclusion for clearance lamps mounted other than on the front or rear of a vehicle where necessary to indicate overall vehicle width or protect the lamps from damage, appearing in paragraph S5.3.2.1 of the current version of FMVSS No. 108, does not appear in the NPRM. The exclusion for mounting location does appear in the Mounting Location portion of Table I-a for both front and rear clearance lamps (and has been added to Table I-b for trailer clearance lamps). The photometric output exclusion for such lamps appears in Table XI as Footnote 4, which is the appropriate location for this detail.

   TTMA also called attention to an interpretative rule issued by the agency in 1999 and published at 64 FR 16358 \27\

   [[Page 68258]]

   which quantifies the requirement that clearance lamps and identification lamps be mounted ``as near the top as practicable'' and describes how ``practicability'' will be determined for these lamps when mounted on a vehicle with cargo doors. We agree that this interpretative rule concerning presumption of practicability is important to include in FMVSS No. 108. Therefore, we have added to the Mounting Height portion of Table I-a, applicable to rear clearance lamps and rear identification lamps (and to those same lamps in Table I-b applicable to trailers), the sentence ``Practicability of locating lamps on the vehicle header is presumed when the header extends at least 25 mm (1 inch) above the rear doors.''

   \27\ 64 FR 16358, (April 5, 1999).

   ASSN commented that the incorporation of the May 26, 2000 letter of interpretation to Mr. Farber \28\ permitting stop lamps to be activated when a vehicle is slowed by a device designed to retard the motion of a vehicle, should also be extended to activation of a high-mounted stop lamp. The Farber interpretation was issued several years after high- mounted stop lamps were first required on vehicles but does not explicitly address their activation. The current version of FMVSS No. 108 contains, in paragraph S5.5.4, slightly different activation requirements for stop lamps and for high-mounted stop lamps. It states, ``The stop lamps on each vehicle shall be activated upon application of the service brakes. The high-mounted stop lamp on each vehicle shall be activated only upon application of the service brakes'' (emphasis added). This difference in activation requirements is explained in the September 10, 1990 letter of interpretation to Mr. Henneberger \29\ which states, `` * * * The second sentence of S5.5.4 restricts operation of the center stop lamp to application of the service brakes, but no such restriction exists in the first sentence. Although the first sentence requires operation of the stop lamps upon application of the service brakes, when considered in conjunction with the restriction stated in the second sentence, it can be read as implying that there may be other conditions under which activation of the stop lamps is permissible. However the reason for the difference in the two sentences is otherwise. Commonly, in red rear combination lamps, the same filament serves both the stop and turn signal functions. If the turn signal is functioning when the brakes are applied, the first sentence ensures that the stop signal overrides the turn signal.''

   \28\ http://isearch.nhtsa.gov/files/21341.ztv.html \29\ http://isearch.nhtsa.gov/gm/90/nht90-3.93.html

   The Farber interpretation was incorporated into the NPRM because of its conclusion that, `` * * * when a vehicle is slowed by downshifting or an engine retarder, from the perspective of the following driver, it would be equivalent to what would occur if the service brakes were applied. Therefore, it would be permissible for the stop lamps to be illuminated under this scenario, since such illumination would not create any confusion in the mind of a following driver and thus would not ``impair the effectiveness'' of the required stop lamps.'' Clearly, the Farber interpretation establishes a situation where the action of a retarder or similar device is equivalent to the action of applying the service brakes. Since S5.5.4 of the current version of FMVSS No. 108 requires activation of the high-mounted stop lamp when the service brake is applied, it follows that it may also be activated by application of a retarder. Table I-a of the final rule has been revised to include this permitted activation.

   AAM recognized a typographical error in Table I-a in describing the mounting location requirements for school bus signal warning lamps. AAM suggested language that is more faithful to that of SAE J887, School Bus Red Signal Lamps, July 1964, the document incorporated by reference in the current version of Standard No. 108. We have revised the language of the final rule applicable to the mounting location of these lamps to state, `` * * * but in no case shall the spacing between lamps be less than 40 inches'', which is more faithful to SAE J887.

   Nissan commented that inclusion of the Daytime Running Lamp (DRL) in a Table titled Required Lamps and Reflective Devices implied that the DRL was the only non-required lamp permitted on regulated vehicles. We have discussed previously that we believe Table I-a is the appropriate location for the DRL in the standard. However, we have clarified the portion of Table I-a applicable to the DRL by revising the title from ``Additional Lamps Allowed * * *'' to ``Daytime Running Lamps Allowed * * *.''

   Nissan and AAM commented that Table I-a did not completely describe all mounting height restrictions on DRLs in the appropriate portion of the table. We have clarified in Table I-a that additional requirements do apply and are included in paragraph S7.10.13(b) of the final rule.

   Guide commented that additional DRL activation requirements are contained in paragraph S7.11.2 of the NPRM and should be added to Table I-a. We disagree. There is language in Table I-a calling attention to these additional requirements and directing users to paragraph S7.10.10.1(c) of the final rule, a notice that we believe is adequate. Table I-b Portion of Proposed Table I

   In addition to those revisions to Table I-b that were listed in the preceding section, several others have been incorporated in the final rule.

   AAM commented that the width criteria for installing a single taillamp, stop lamp, or rear reflex reflector on a trailer was incorrectly dimensioned. Table I-b stated that the installation of a single such device can occur ``* * * on trailers less than 760 mm wide.'' The correct dimension from paragraph S5.1.1.14 of the current version of FMVSS No. 108 is 30 inches, and the final rule states that dimension for all three devices. Current paragraph S5.1.1.14 also states that when single devices are used, they shall be located ``* * * at or near its vertical centerline.'' To clarify this requirement, we have revised the Mounting Location requirement language from ``A single lamp (reflector) must be mounted at or near the vertical centerline'' to ``When a single lamp (reflector) is installed, it must be mounted at or near the vertical centerline.''

   AAM, Grote, and Koito all commented that the NPRM did not include the mounting height limitation of 60 inches for rear side marker lamps installed on trailers 2032 mm or more in overall width, which is stated in Table II of the current version of FMVSS No. 108. This omission is corrected in Table I-b in the final rule.

   TTMA commented on the appropriate location for the requirement stating that conspicuity treatment on a trailer can serve as the required reflex reflectors if the conspicuity treatment is placed at the locations required for reflex reflectors. This alternative is contained in paragraph S6.1.1.1.1 in the NPRM, but we agree it is best located in Table I-b and have moved it there, following the listing of ``Reflex Reflectors'' and ``Intermediate Reflex Reflectors'', and have eliminated paragraph S6.1.1.1.1 from the final rule.

   TTMA commented that the requirements for mounting height for clearance lamps and identification lamps in Table I-b was missing. We have corrected this by adding the appropriate language from Table II of the current version of FMVSS No. 108,

   [[Page 68259]]

   ``As near the top as practicable.'' We have also added language to the Mounting Height portion of the rear clearance lamp section stating that, similar to Table I-a, they are not required to be mounted as near the top as practicable when the rear identification lamps are mounted at the extreme height of the vehicle, an exclusion provided by paragraph S5.3.1.4 of the current version of FMVSS No. 108 and inadvertently omitted from the NPRM. Table I-c Portion of Proposed Table I

   Consistent with the revision in language to the Number and Color portion of headlamps in Table I-a, we have revised Table I-c. It previously stated ``* * * of a type and number listed * * *,'' but now states ``* * * of a headlighting system listed * * *.'' We believe that this revision more precisely describes this requirement.

   AAM commented that there are additional motorcycle headlamp mounting restrictions that are not acknowledged in Table I-c. We agree and have added language to direct the reader to paragraphs S10.17.1.1, S10.17.1.2, and S10.17.1.3 of the final rule for additional headlamp mounting requirements.

   We have inserted the language ``a turn signal'' between the words ``between'' and ``lamp'' in the last sentence of the Mounting Location portion of the front turn signal lamp requirements section of Table I-c of the final rule to clarify that requirement. Also, the language of the last sentence of the Mounting Location portion of the rear turn signal lamp requirements section of Table I-c was revised so that it now states, ``* * * between the turn signal lamp and taillamp or stop lamp is 4 inches * * *,'' a change that clarifies the requirement in the final rule. Table II-a Headlighting Systems--Sealed Beam

   GE, Honda, AAM, and Koito commented that the reference to photometry requirements in Table XIX of the NPRM for a lower beam visual aim ``LF'' headlamp erroneously stated ``LB1(1)'' rather than ``LB1V(1).'' We agree and this has been corrected in the final rule. Table II-b Headlighting Systems--Combination

   GE, Honda, AAM, and Koito commented that the reference to photometry requirements in Table XIX of the NPRM for a 4 lamp system, lower beam visual aim headlamp erroneously stated ``LBV(4)'' rather than ``LB1V(4).'' We agree and this has been corrected in the final rule.

   Koito commented that if an integral beam headlamp was used in a combination headlighting system, it could consist of beam contributors and if so, they would be subject to the photometric allocation formula described in paragraph S6.8.5.6.6 of the NPRM. Koito requested that a footnote be added to call attention to that possibility. We agree and have added Footnote 7 to the final rule stating ``Beam contributor photometric allocation formula of paragraph S14.2.5.9 may apply.'' Table II-c Headlighting Systems--Integral Beam

   Footnote 6 was revised for clarity in the final rule to read, ``Beam contributor photometric allocation formula of paragraph S14.2.5.9 applies.''

   Koito commented that the lower beam photometry requirements reference in the NPRM for the headlamp in a four lamp system that provides a portion of the upper beam and the lower beam should be ``LB3M'' rather than ``LB4M'' for a mechanically aimed headlamp and ``LB3V'' rather than ``LB2V'' for a visually/optically aimed headlamp. These references are taken from paragraph S7.4(a)(1)(iii) of the current version of FMVSS No. 108, which specifies Figure 28-1 or Figure 28-2. LB4M is a restatement of the requirements of Figure 28-1 and LB2V similarly of Figure 28-2.\30\ We do not agree with Koito's comment and are therefore making no revision in the final rule.

   \30\ And also Figure 17-2 which has identical requirements.

   Table II-d Headlighting Systems--Replaceable Bulb

   AAM and Koito commented that the references in Table II-d to photometry requirements in Table XIX for UB1, LB1M, and LB1V should include Footnote 4, ``Lower beams may remain activated when upper beams are activated,'' based upon paragraph S5.8.8 of the current version of FMVSS No. 108. We agree that the UB1, LB1M, and LB1V requirements are derived from Figures 15-1 and 15-2 of the current version of FMVSS No. 108. Paragraph S5.8.8 states that a headlighting system designed to conform to the photometric requirements of Figures 15-1 and 15-2 may be so wired. That footnote has been added to the final rule.

   Koito and AAM commented that the photometric requirement reference in Table II-d of the NPRM for the upper beam of a 2 lamp system with a light source composition of HB2 or any single filament type used alone or with any other single or dual filament type, should include UB3 (Figure 27-1 or 27-2 in the current version of FMVSS No. 108) as well as the listed UB2 (Figure 17-1 or 17-2 in the current version of FMVSS No. 108). They provide the rationale that this is permitted by paragraph S7.5(d)(2)(ii)(A)(1) of the current version of FMVSS No. 108. Indeed, a literal reading of that text could lead to such a conclusion. However, Figure 26, Table for Determining the Photometric Requirements of Replaceable Bulb Headlamp Systems, of the current version of FMVSS No. 108 clearly shows, in the box where the row marked ``Two-Headlamp System'' intersects the column marked ``HB2 or Any Single Filament Type used Alone or with Any Other Single or Dual Filament Type,'' that the applicable photometry requirements are those of Figure 17-1 or 17- 2.\31\ Faced with the seeming contradiction between paragraph S7.5 (d)(2)(ii)(A)(1) and Figure 26, we looked for other cues in FMVSS No. 108 that would confirm the correct requirement. One such cue is in paragraph S7.5(b) which states that, ``The photometrics as specified in subparagraphs (c) through (e) of this paragraph (depicted in Figure 26), using any light source of the Type intended for use in such system.'' This clearly indicates that paragraph S7.5 and Figure 26 provide identical information. Another cue is the language in paragraph S7.5(d)(2)(i)(A)(2) which states that only the photometry requirements of Figure 17-1 or 17-2 are to be used for lower beam with a two lamp system that uses an HB2 source.

   \31\ The current version of FMVSS 108 presents headlamp photometry requirements in sets of related tables that differ only by application to type of aiming system used. In this instance Table 17-1 applies to mechanically aimed headlighting systems while Table 17-2 applies to visually/optically aimed headlighting systems.

   The specific language of paragraph S7.5(d)(2)(ii)(A)(1) first appeared in Standard No. 108 several years ago during a revision in text. Instead of concluding with ``* * * light sources that include Type HB2 * * *'' paragraph S7.5(d)(2)(ii)(A)(1) should have concluded with ``* * * light sources other than Type HB2 * * *'' This would make it consistent with paragraph S7.5(d)(2)(i)(A)(1), which addresses the lower beam, and Figure 26.

   Because this ambiguity has existed for a considerable length of time, it would be a substantive change to revise it in the final rule and thus is outside the scope of the rewrite. We have revised

   [[Page 68260]]

   Table II-d in the final rule to indicate that UB3 may be used as an upper beam photometry requirement for a 2 lamp system using a Type HB2 or any single filament type used alone, or with any other single or dual filament type. However, regulated parties should be aware that we consider this to be incorrect and we may take action soon to correct what we believe is a mistake. Table III Conspicuity Systems Requirements Becomes Table III Marking Requirements Location

   The recognition that the tabular method of organization did not work well for the presentation of lengthy textual requirements provided the rationale for moving the conspicuity systems requirements content of Table III of the NPRM to paragraph S8.2 of the regulatory text of the final rule. The substantive issues raised by public comment and the revisions to conspicuity systems are discussed under paragraph S8.2. As discussed under paragraph S6.5, Table III has been re-designated as a source for listing each location in the regulatory text of the final rule applicable for each marking requirement of Standard No. 108. Table IV Effective Projected Luminous Lens Area Requirements

   As previously mentioned, this table has been divided into three sections in the final rule.

   Koito and Guide commented that the effective projected luminous lens area requirements for a front turn signal lamp were incorrectly stated in what is now Table IV-a and did not agree with the requirements of SAE J588 NOV84. We concur and have clarified those requirements in the final rule to indicate that there is no effective projected luminous lens area requirement for each compartment of a multiple compartment front turn signal lamp.

   There were no comments submitted that impacted what are now Tables IV-b and IV-c in the final rule. Table V Visibility Requirements of Installed Lighting Devices

   As previously mentioned, this table has been divided into four sections. AAM suggested that the column marked ``Applicable Vehicles'' was not needed. We agree and have removed it from all four sections of Table V in the final rule. Table V-a Visibility Requirements of Installed Lighting Devices

   AAM suggested alternative language referring to the required visibility of high-mounted stop lamps when two lamps are installed. We agree with its suggestion and have revised the language of the final rule appearing in parenthesis to read (Single lamp or two lamps together where required by paragraph S6.1.1.2 of this standard.) Table V-b Visibility Requirements of Installed Lighting Devices (Lens Area Visibility Option)

   Grote suggested that the mandatory enforcement dates for the exclusive use of the visibility options of Table V-b and V-c be included in those tables. We believe it is preferable to include these dates in paragraph S6.4.4 of the regulatory text of the final rule, where additional details about choosing a visibility compliance method are located.

   AAM suggested that the language of Footnote 2 of Table V-b (and Footnote 2 of Table V-c) be revised for clarity. We agree and those footnotes now read in the final rule, ``Where a lamp is mounted with its axis of reference less than 750 mm above the road surface, the vertical test point angles located below the horizontal plane subject to visibility requirements may be reduced to 5[deg] down.'' Table V-c Visibility Requirements of Installed Lighting Devices (Luminous Intensity Visibility Option)

   AAM claimed that the visibility requirements specifying corner points at 80[deg] outboard are erroneous. We disagree because these corner points are faithful to those stated in Figure 20 of the current version of FMVSS No. 108. Table V-d Visibility Requirements of Installed Lighting Devices (Legacy Visibility Alternative)

   AAM identified a typographical error in the proposal where a period did not directly follow the abbreviation ``mm'' in the required visibility of turn signal lamps. This has been corrected in the final rule by removing all periods after these abbreviations in keeping with the style of regulatory text.

   Nissan believed that the term ``existing'' in the parenthetical subtitle of this section was indeterminate and suggested it be removed. We decided to revise the subtitle from ``(Existing SAE Visibility Alternative)'' to ``(Legacy Visibility Alternative)'' in the final rule suggesting that these requirements are ones that have historically been used.

   Guide commented that the sentence ``Where more than one lamp or optical area is lighted on each side of the vehicle, only one such area on each side need comply'' should not be included in visibility requirements. We disagree because it is an integral part of the SAE documents incorporated by reference in the current version of FMVSS No. 108.\32\

   \32\SAE J1395 APR85, S5.4.1, SAE J586 FEB84, S5.4.1, SAE J1398 MAY85, S5.4.1, and SAE J585e, September 1977, S4.

   Guide also suggested that the phrase ``To be considered visible'' preface the specific visibility requirements in Table V-d. We believe that the language of the requirements in Table V-d, along with the text of paragraph S6.4.4, clearly describe what is required and the additional language is not needed.

   We have revised the visibility requirement minimum value for a taillamp in Table V-d from 1250 sq mm to 2 sq in to be faithful to the language of SAE J585e, September 1977, Section 4, incorporated by reference in the current version of FMVSS No. 108, which is the original source of this requirement. Table VI Front Turn Signal Lamp Photometry Requirements

   As previously mentioned, this table has been divided into two sections. Table VI-a contains the base front turn signal lamp photometry requirements and the 2.5 times base front turn signal lamp photometry requirements. Table VI-b contains the 1.5 times base and the 2.0 times base front turn signal lamp photometry requirements.

   Nissan, AAM, and Koito commented that displaying the ratio requirements for both turn signal lamps combined with parking lamps and turn signal lamps combined with clearance lamps in the same column of our proposal was confusing. We agree and have placed the requirements for those two combinations in separate columns in both Tables VI-a and VI-b in the final rule.

   Koito and AAM commented that Footnote 4 does not accurately state the requirements of SAE J1395 AP85, Section 5.1.5.2, incorporated by reference in the current version of FMVSS No. 108. We agree and have revised that footnote in the final rule to read ``When a clearance lamp on a vehicle 2032 mm or more in overall width is combined with a front turn signal lamp and the maximum luminous intensity of the clearance lamp is located below horizontal and within a 1.0[deg] radius around the test point, the ratio for the test point may be computed by using the lowest value of the clearance lamp luminous intensity within the generated area.''

   AAM noted several instances where the group minimum photometric intensity values for 2 and 3 lighted sections, 2.5x base photometry lamps, were erroneous. These five values were

   [[Page 68261]]

   all 0.5 cd less than their calculated values. The correct values have been incorporated in Table VI-a in the final rule.

   Koito suggested that several of the group minimum photometric intensity values for 2 lighted sections, base photometry lamps, are erroneous. Koito appears to have based its comment on the observation that the arithmetic sum of the minimum values of all test points included in the groups exceeds the value shown for the group. However, in this case all of the listed values are accurate. They are consistent with values of Table 1 for group requirements and Table 3 for individual test point requirements of SAE J588 NOV84, incorporated by reference in the current version of Standard No. 108. Although in most cases SAE has specified that group photometric values equal the sum of the individual test point values in a group, there are exceptions, and this is one of those exceptions. Table VII Rear Turn Signal Photometry Requirements

   Footnote 6 of the final rule was revised to agree with the decision to eliminate the reference to SAE J588e for double faced turn signal lamps installed on truck tractors. It now reads, ``A double-faced turn signal lamp installed as described in paragraph S6.1.1.3 on a truck tractor need only meet the photometric requirements for a left side lamp where the lamp is mounted on the left side of the vehicle, and for a right side lamp where the lamp is mounted on the right side of the vehicle.'' Table VIII Taillamp Photometry Requirements

   Calcoast commented that Footnote 1 and Footnote 2 to Table VIII of the NPRM are not mutually exclusive. Therefore, the limitations imposed by compliance with one of these footnotes may negate an allowance offered by the other. We agree with Calcoast's assessment. The situation that it mentioned actually affects all lamps where grouped test point photometric compliance is permitted. The requirements of Footnote 1 of Table VIII also apply to all other lamps where grouped compliance is permitted. The original source of this requirement is SAE J575, Test for Motor Vehicle Lighting Devices and Components, paragraph J, which is identical in both J575d, August 1967, and J575e, August 1970, the two versions of this standard applicable to signal lamps in FMVSS No. 108. Footnote 2 of Table VIII describes the basic premise of grouped compliance. The failure of an individual test point in the group to meet its minimum photometric intensity can be offset if one or more of the other points in the group exceed their minimum intensity requirement by enough margin that the group total intensity is still met.

   Additionally, turn signal lamps and stop lamps, including high- mounted stop lamps, also have a further limitation from their original SAE source document concerning how much any individual test point can fail to meet its minimum intensity when considered in a group compliance situation. This limitation states that the measured value at each test point must not be less than 60% of the minimum value.

   All these limitations must be considered simultaneously when determining grouped photometric compliance for lamps where that procedure is permitted. Calcoast was correct in its assessment that these limitations may negate full utilization of each other.

   Koito and AAM identified two minimum test point photometric intensity values for 3 lighted section lamps they believe are erroneous. We agree and have corrected the values at 5L-10D and 5R-10D in the final rule.

   We have also revised Table VIII in the final rule to reduce confusion by placing the minimum and maximum photometric intensity values in separate columns for each of the lighted sections alternatives.

   Koito commented that Table VIII did not include Footnote 5 from Table 1 of SAE J585e, Tail Lamps (Rear Position Lamps), September 1977, incorporated by reference in the current version of FMVSS No. 108. This footnote limits the size of the area of maximum photometric intensity in a specified portion of the photometric pattern. This requirement was added to Table VIII in the final rule and now reads, ``A taillamp shall not exceed the maximum intensity over any area larger than that generated by a 0.25[deg] radius, within a solid cone angle from 20[deg]L to 20[deg]R and from H to 10[deg]U.'' Table IX Stop Lamp Photometry Requirements

   The alternative photometric intensity requirements for a stop lamp installed on a motor driven cycle that were included in Table IX in the NPRM have been relocated to new Table XIII in the final rule. This relocation means that Footnote 5 is no longer needed in Table IX and it has been eliminated. Footnote 7 of the NPRM has been redesignated as Footnote 5 in the final rule.

   Honda, AAM, and Koito all observed an erroneous group minimum photometric intensity value for 3 lighted sections in group 3. The correct value is 520 cd instead of the listed 445 cd. This error is corrected in Table IX of the final rule.

   In Table IX of the NPRM, it was stated that when a stop lamp is combined with a taillamp, the luminous intensity of the stop signal must exceed the luminous intensity of the tail signal at each test point by a certain minimum ratio. This ratio value is common for all vehicles at all test points with the exception of the test point H- 5L.\33\ Proposed Table IX showed the ratio value at this point as 3/5 \(6)\ and further states at Footnote 6, ``Values preceded by a slash (/ ) apply only to lamps installed on multipurpose passenger vehicles, trucks, trailers, and buses, of 2032 mm or more in overall width.'' Thus, the requirement at the H-5L test point is that the luminous intensity of the stop lamp exceed the luminous intensity of the combined taillamp by at least 3 times on multipurpose passenger vehicles, trucks, trailers, and buses, of 2032 mm or more in overall width, and by at least 5 times on other applicable vehicles which includes all passenger cars and motorcycles and all multipurpose passenger vehicles, trucks, trailers, and buses, less than 2032 mm in overall width. This discrepancy exists due to the language from which the ratio requirements are derived. SAE J586 FEB84, Stop Lamps for use on Motor Vehicles Less Than 2032 mm in Overall Width, incorporated by reference in the current version of FMVSS No. 108 states in Section 5.1.5.3, ``When a tail lamp is combined with the stop lamp, the stop lamp shall not be less than three times the luminous intensity of the tail lamp at any test point; except that at H-V, H-5L, H-5R, and 5U-V, the stop lamp shall not be less than five times the luminous intensity of the tail lamp.'' Similarly, SAE J1398 MAY85, Stop Lamps for use on Motor Vehicles 2032 mm or More in Overall Width, incorporated by reference in the current version of FMVSS No. 108, states in Section 5.1.5.2, ``When a tail lamp is combined with the stop lamp, the stop lamp shall not be less than three times the luminous intensity of the tail lamp at any test point; except that at H-V, H-5R, and 5U-V, the stop lamp shall not be less than five times the luminous intensity of the tail lamp.'' Thus, the requirements are identical with the exception of test point

   [[Page 68262]]

   H-5L. By not specifically identifying H-5L as a test point requiring a 5:1 ratio, SAE J1398 MAY85, by default, requires a 3:1 ratio.

   \33\ In the final rule we have elected to implement a suggestion by Calcoast to identify photometric test points consistently in the photometric requirements tables. We have chosen to list lateral values in the left column and vertical values in the right column. Thus the H-5L test point of Table IX of the NPRM appears as test point 5L-H in the final rule.

   SAE J585e, Tail Lamps (Rear Position Lamps), September 1977, also incorporated by reference in the current version of FMVSS No. 108 (applicable to all vehicles), also contains a ratio requirement. Footnote 4 to Table 1 of that document states, ``When a tail lamp is combined with the turn signal lamp or the stop lamp, the signal lamp or stop lamp shall not be less than three times the candlepower \34\ of the tail lamp at any test point; except that at H-V, H-5L, H-5R, and 5U-V, the signal lamp or stop lamp shall not be less than five times the candlepower of the tail lamp.'' Thus, there is a documented conflict regarding the ratio requirement at the H-5L test point on combined stop lamps and taillamps used on wide vehicles. We resolved this in the final rule by maintaining the dual requirements stated in the NPRM. That is the ratio of stop lamp intensity to taillamp intensity at that test point remains 3:1 for lamps installed on multipurpose passenger vehicles, trucks, trailers, and buses, of 2032 mm or more in overall width, and 5:1 for lamps installed on all passenger cars and motorcycles and all multipurpose passenger vehicles, trucks, trailers, and buses, less than 2032 mm in overall width.

   \34\ The term ``candlepower'' used in this context means the contemporary unit of measurement used to express the luminous intensity attribute.

   Although we believe there is ample evidence that the 3:1 ratio was never intended by SAE, to rectify this error at this time would constitute a substantive change and therefore be beyond the scope of the FMVSS No. 108 rewrite. We may address this issue in the near future. Table X Side Marker Photometry Requirements

   Footnote 1 was revised to be more consistent with paragraph S7.4.1.1 of the NPRM (paragraph S7.4.13.2 of the final rule) concerning the widths of vehicles that can use reduced photometric compliance angles between the front and rear side marker. Footnote 1 now reads, ``Where a side marker lamp installed on a motor vehicle less than 30 feet in overall length and less than 80 inches (2 m) in overall width has the lateral angle nearest the other required side marker lamp on the same side of the vehicle reduced from 45[deg] by design as specified by S7.4.13.2, the photometric intensity measurement may be met at the lesser angle.'' The change in width from 2032 mm to 80 inches (2 m) was made to be faithful to Footnote b of SAE J592e, Clearance, Side Marker, and Identification Lamps, July 1972. Table XI Clearance and Identification Lamps Photometry Requirements

   Koito and AAM commented that Footnote 3 to Table XI did not include the limitation on a turn signal lamp combined with a red clearance lamp as required by SAE J592e, July 1972, Table 1 Footnote ``a'', incorporated by reference by the current version of FMVSS No. 108. This is corrected in the final rule.

   Grote believed that the maximum photometric intensity for a red clearance lamp should be 18 cd. We disagree because SAE J592e, July 1972, incorporated by reference in the current version of FMVSS No. 108, states in Footnote ``a'' to Table 1 that 15 cd is the maximum allowed for a red clearance lamp. Table XII Backup Lamp Photometry Requirements

   Guide commented that Footnotes 2 and 3 only apply to groups 1, 2 5, and 6. We agree. Figure 2, Footnote 1 of the current version of Standard No. 108 is the source of these requirements and the Guide assertion is consistent with that figure. We revised Table XII accordingly in the final rule.

   Guide suggested replacing the phrase ``same or symmetrically opposite design'' in Footnote 2 of Table XII of the NPRM with the phrase ``symmetrical beam pattern'' and also replacing the phrase ``differing design'' in Footnote 3 of Table XII with the phrase ``asymmetrical beam pattern'', claiming the terminology of the NPRM is vague. Guide offered no argument as to why the suggested replacement phrases would improve understanding. Since the language of the NPRM is faithful to the current version of FMVSS No. 108, we are not implementing its suggestion in the final rule.

   We have added the term ``Each Lamp'' after the title ``Two Lamp Systems'' in Table XII of the final rule to clarify that each lamp of a two lamp system is to be designed to conform to either the individual test point photometry requirements or the group photometry requirements. Table XIII-a Motorcycle Turn Signal Lamp Alternative Photometry Requirements Table XIII-b Motor Driven Cycle Stop Lamp Alternative Photometry Requirements

   Table XIII of the NPRM, License Plate Lamp Target Locations, has been redesignated as Figure 19 in the final rule. A new Table XIII has been created that includes the alternative stop lamp requirements for motor driven cycles, which were previously part of Table IX in the NPRM and the optional turn signal requirements for motorcycles noted in paragraphs S7.1.1.1 and S7.1.2.1 of the NPRM, but not previously tabularized. Table XIV Parking Lamp Photometry Requirements

   There were no comments submitted that impacted Table XIV beyond those previously mentioned. Table XV High-Mounted Stop Lamp Photometry Requirements

   AAM suggested that Footnote 4 of Table XV be incorporated directly into the table where the maximum photometric intensity is stated. AAM offered no arguments to support this request and we can see no compelling reason to implement it. Table XV appears in the final rule identical to the NPRM. Table XVI

   As previously mentioned, Table XVI of the NPRM has been partitioned into three sections, Table XVI-a, Reflex Reflector Photometry Requirements, Table XVI-b, Additional Photometry Requirements for Conspicuity Reflex Reflectors, and Table XVI-c, Retroreflective Sheeting Photometry Requirements. The content of these tables in the final rule is identical to that of the NPRM. Table XVII School Bus Signal Lamp Photometry

   There were no comments submitted that impacted Table XVII. Table XVIII Headlamp Upper Beam Photometry Requirements

   There were no comments submitted that impacted Table XVIII beyond those previously mentioned. Table XIX Headlamp Lower Beam Photometry Requirements

   Table XIX, Headlamp Lower Beam Photometry Requirements, has been split into Tables XIX-a, XIX-b, and XIX-c in the final rule.

   GE, Honda, AAM, and Koito identified that the maximum photometric intensity value of 2,500 cd for the 0.5D-1.5L to L test location of a LB4M beam was inadvertently omitted from Table XIX of the NPRM. We agree and this value has been added in the final rule.

   Guide suggested a reduction in the lateral limits in the NPRM for photometry of the 10[deg]U to 90[deg]U glare

   [[Page 68263]]

   area from 90[deg]L to 90[deg]R to 45[deg]L to 45[deg]R but offered no basis to support this request. Such a revision would be substantive and beyond the scope of the rewrite, therefore this suggestion was not pursued in the final rule. Table XX Motorcycle and Motor Driven Cycle Headlamp Photometry Requirements

   Honda and Koito identified that the maximum photometric intensity value of 12,500 cd for the 4D-4R test location for a motor driven cycle headlamp was inadvertently placed in the minimum intensity column of Table XX of the NPRM. The value has been placed in the correct location in the final rule.

   AAM suggested that the column heading shown for lower beam headlamps be replicated for upper beam headlamps. We agree that doing so would improve clarity and have incorporated the headings in Table XX of the final rule. Table XXI Associated Equipment Physical Test Requirements (Table eliminated in final rule)

   The recognition that the tabular method of organization did not work well for lengthy textual requirements provided the rationale for moving the associated equipment physical test requirements content of Table XXI of the NPRM to paragraph S14.9 of the regulatory text in the final rule.

   The substantive issues raised by public comment and the revisions to associated equipment physical test requirements are discussed under paragraph S14.9.

   Table XXII Lamp and Reflective Devices Physical Test Requirements (Table eliminated in final rule)

   The recognition that the tabular method of organization did not work well for lengthy textual requirements provided the rationale for moving the lamp and reflective devices physical test requirements content of Table XXII of the NPRM to paragraphs S14.3, S14.4, and S14.5 of the regulatory text in the final rule.

   The substantive issues raised by public comment and the revisions to lamp and reflective devices physical test requirements are discussed under those sections. Table XXIII Headlamp Physical Test Requirements (Table eliminated in final rule)

   The recognition that the tabular method of organization did not work well for lengthy textual requirements provided the rationale for moving the headlamp physical test requirements content of Table XXIII of the NPRM to paragraphs S14.6, S14.7, and S14.8 of the regulatory text in the final rule.

   The substantive issues raised by public comment and the revisions to headlamp physical test requirements are discussed under those sections. Figures Figures 1 through 12 and 15 through 18

   There were no comments submitted that impacted Figures 1 through 12 or Figures 15 through 18. Figure 13 Tractor Conspicuity Treatment Examples

   TMA commented that Figure 31 of the current version of FMVSS No. 108, rather than Figure 13 of the NPRM, better illustrated that the right angle white conspicuity treatment element required on the upper rear outside corners of truck tractors may not be continuous if cab mounted hardware makes this impractical. We have revised Figure 13 to illustrate this condition in the final rule. Figure 14 92 x 150 mm Headlamp Aim Deflection Test Setup

   GE identified 13 omissions or errors in Figure 14 of the NPRM that were corrected in the final rule to agree with the source document, Figure 16 of the current version of FMVSS No. 108. Figure 15 Types G & H Headlamp Aim Deflection Test Setup

   GE identified an omission in Figure 15 that was corrected to agree with the source document, Figure 22 of the current version of FMVSS No. 108. Figure 19 License Plate Lamp Target Locations

   Figure 19, License Plate Lamp Target Locations, was designated as Table XIII in the NPRM. The supplementary response from the AAM/ASSN suggested changing it to be a figure. Its purpose is illustrative, so it is most appropriately designated as a figure.

   AAM requested that the English units of measurement, which were part of the source drawings, SAE J587 OCT81 Figures 1 and 2, but not included in Table XIII of the NPRM, be restored. This was done, as Figure 19 is dimensioned in both metric and English units in the final rule. Figure 20 License Plate Lamp Measurement of Incident Light Angle

   AAM requested that Figure 3 of SAE J587 OCT81, License Plate Lamps, be included to better illustrate the incident light angle requirement of paragraph S7.7.1.1 of the NPRM. We agree and have included it as Figure 20, License Plate Lamp Measurement of Incident Light Angle, in the final rule. It is referenced in paragraph S7.7.15.4 of the final rule. Figure 21 Vibration Test Machine

   AAM requested that SAE J577, Vibration Test Machine, April 1964, be directly incorporated into FMVSS No. 108 rather than to continue to be incorporated by reference. Figure 1, Vibration Test Machine, and Table 1, Cam Profile Radii, (from SAE J577) were redrawn for the final rule as Figure 21, Vibration Test Machine. Figure 22 Flasher Standard Test Circuit

   Figure 22 includes the standard test circuit of SAE J823b, Flasher Test Equipment, April 1968. The procedures of SAE J823b have also been incorporated into paragraph S14.9 of the final rule, allowing the subreference by incorporation of this standard to now be eliminated from FMVSS No. 108.

   IV. The Final Rule

   After careful consideration of public comments on the NPRM, the agency has decided to publish a final rule to amend 49 CFR Part 564 and FMVSS No. 108 as discussed below:

1. 49 CFR Part 564

   We are relocating figures addressing sealed beam headlamps that currently reside in FMVSS No. 108 and SAE J1383 APR85 into a newly created Appendix C of 49 CFR Part 564. We have listed those specific figures and where they currently reside in FMVSS No. 108 or SAE J1383 APR85 in the reference document in Appendix C of this notice. In addition, we are making the applicable changes to the scope and purpose provisions of Part 564 to account for the newly formed Appendix C. Unlike Appendices A and B, there will be no further additions to, or modifications of, the sealed beam headlamp figures in Appendix C.

2. 49 CFR Part 571.108

   We are amending Standard No. 108 by: (1) Reorganizing the regulatory text so that it provides a more straight-forward and logical presentation of the applicable regulatory requirements; (2) including important agency interpretations of the existing requirements; and (3) reducing reliance on third-party documents incorporated by reference. This has resulted in additional tables and figures being added to the standard. In addition, the structure of the standard has been changed to present the requirements in a more standardized and user-friendly manner.

   [[Page 68264]]

   V. Benefits and Costs

   Because this proposal only reorganizes the existing requirements of the standard, we do not anticipate that there would be any costs or benefits associated with this rulemaking action to implement an administrative rewrite of FMVSS No. 108, other than the benefits associated with a clearer, easier-to-read standard. None of the public comments identified any instances where the rewritten standard would have a cost effect. Accordingly, the agency did not conduct a separate economic analysis for this rulemaking.

   VI. Rulemaking Analyses and Notices

1. Vehicle Safety Act

   Under 49 U.S.C. Chapter 301, Motor Vehicle Safety (49 U.S.C. 30101 et seq.), the Secretary of Transportation is responsible for prescribing motor vehicle safety standards that are practicable, meet the need for motor vehicle safety, and are stated in objective terms.\35\ These motor vehicle safety standards set the minimum level of performance for a motor vehicle or motor vehicle equipment to be considered safe.\36\ When prescribing such standards, the Secretary must consider all relevant, available motor vehicle safety information.\37\ The Secretary must also consider whether a proposed standard is reasonable, practicable, and appropriate for the type of motor vehicle or motor vehicle equipment for which it is prescribed and the extent to which the standard will further the statutory purpose of reducing traffic accidents and associated deaths.\38\ The responsibility for promulgation of Federal motor vehicle safety standards has been delegated to NHTSA. \39\

   \35\ 49 U.S.C. 30111(a).

   \36\ 49 U.S.C. 30102(a)(9).

   \37\ 49 U.S.C. 30111(b).

   \38\ Id.

   \39\ 49 U.S.C. 105 and 322; delegation of authority at 49 CFR 1.50.

   FMVSS No. 108, Lamps, Reflective Devices, and Associated Equipment, was originally established in a final rule published in the Federal Register on February 3, 1967 (32 FR 2408). The purpose of the standard is to reduce traffic accidents and deaths and injuries resulting from traffic accidents, by providing adequate illumination of the roadway, and by enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood, both in daylight and in darkness or other conditions of reduced visibility. Since the time of the standard's initial promulgation, the agency has undertaken numerous rulemakings and interpretations related to Standard No. 108, in many cases to deal with the emergence of new lighting technologies. In recent years, concerns have been raised that after nearly four decades of amendment, navigating the requirements of the standard has become increasingly difficult. Therefore, in this final rule, the agency is implementing an administrative rewrite of Standard No. 108 in order to improve its structure and clarity, without changing any of its existing substantive requirements. In preparing this final rule, the agency carefully considered the statutory requirements of 49 U.S.C. Chapter 301.

   First, this final rule reflects the agency's careful consideration and analysis of all existing regulatory provisions of FMVSS No. 108, as well as salient letters of interpretation related to that standard. In developing the substantive provisions of the standard over the years, the agency considered all relevant, available motor vehicle safety information, including available research, testing results, and other information related to various technologies. This administrative rewrite does not change any of these existing provisions or the underlying basis therefore. The final rule also reflects the agency's consideration of information offered in public comments on the notice of proposed rulemaking which preceded today's final rule.

   Second, to ensure that the requirements of FMVSS No. 108 are practicable (as well as consistent with our safety objectives), the agency evaluated the cost, availability, and suitability of the standard's provisions, both when initially adopted and during subsequent amendments. As noted above, the changes resulting from this final rule are administrative in nature and would not impact the costs and benefits of the standard. In sum, we believe that this final rule is practicable, and we expect it to maintain the benefits of Standard No. 108.

   Third, the regulatory text following this preamble is stated in objective terms in order to specify precisely what performance is required and how performance will be tested to ensure compliance with the standard. In certain cases, the final rule modifies the language of the standard to improve clarity or to incorporate existing interpretations, again without changing the substance of the existing requirements.

   Fourth, we believe that this final rule meets the need for motor vehicle safety by clarifying the safety standard, thereby making it easier for regulated parties to comply with all applicable requirements. The impacts of the substantive provisions on vehicle safety were discussed at the time of adoption of those provisions.

   Finally, we believe that this final rule is reasonable and appropriate for motor vehicles subject to the applicable requirements. As discussed elsewhere in this notice, the modifications to the standard resulting from this final rule are administrative in nature. It does not affect the substance of the requirements or the bases for those requirements, as articulated in earlier rulemakings. Accordingly, we believe that this final rule is appropriate for covered vehicles that are or become subject to these provisions of FMVSS No. 108 because it furthers the agency's objective of preventing crash-related deaths and serious injuries by ensuring adequate illumination of roadways and enhanced conspicuity of motor vehicles.

2. Executive Order 12866 and DOT Regulatory Policies and Procedures

   Executive Order 12866, ``Regulatory Planning and Review'', provides for making determinations whether a regulatory action is ``significant'' and therefore subject to OMB review and to the requirements of the Executive Order. The Order defines a ``significant regulatory action'' as one that is likely to result in a rule that may:

   (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities;

   (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

   (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

   (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

   This rulemaking document was not reviewed by the Office of Management and Budget under Executive Order 12866. The rule is not considered to be significant within the meaning of E.O. 12866 or the Department of Transportation's Regulatory Policies and Procedures (44 FR 11034 (Feb. 26, 1979)). As stated above in Section V, Benefits and Costs, this final rule is not expected to require parties subject to the requirements of the safety standard to alter their existing practices for certifying compliance with Standard

   [[Page 68265]]

   No. 108 or to increase costs of compliance, because the final rule merely reorganizes and clarifies existing requirements. Accordingly, the agency has not prepared any supplemental economic analysis to accompany this rulemaking document.

3. Regulatory Flexibility Act

   Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq., as amended by the Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996), whenever an agency is required to publish a notice of rulemaking for any proposed or final rule, it must prepare and make available for public comment a regulatory flexibility analysis that describes the effect of the rule on small entities (i.e., small businesses, small organizations, and small governmental jurisdictions). The Small Business Administration's regulations at 13 CFR Part 121 define a small business, in part, as a business entity ``which operates primarily within the United States.'' (13 CFR 121.105(a)). No regulatory flexibility analysis is required if the head of an agency certifies the rule will not have a significant economic impact on a substantial number of small entities. SBREFA amended the Regulatory Flexibility Act to require Federal agencies to provide a statement of the factual basis for certifying that a rule will not have a significant economic impact on a substantial number of small entities.

   NHTSA has considered the effects of this final rule under the Regulatory Flexibility Act. I certify that this final rule will not have a significant economic impact on a substantial number of small entities. The rationale for this certification is that the present final rule does not make any substantive changes to this safety standard, so affected parties will be able to continue current practices without change. Accordingly, we do not anticipate that this final rule will have a significant economic impact on a substantial number of small entities.

4. Executive Order 13132 (Federalism)

   NHTSA has examined today's final rule pursuant to Executive Order 13132, ``Federalism'' and concluded that no additional consultation with States, local governments, or their representatives is mandated beyond the rulemaking process. The agency has concluded that the rule does not have Federalism implications, because the rule does not have ``substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and the responsibilities among the various levels of government.''

   Further, no consultation is needed to discuss the preemptive effect of today's rule. NHTSA rules can have preemptive effect in at least two ways. First, the National Traffic and Motor Vehicle Safety Act contains an express preemptive provision: ``When a motor vehicle safety standard is in effect under this chapter, a State or a political subdivision of a State may prescribe or continue in effect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter.'' 49 U.S.C. 30102(b)(1).

   In addition to the express preemption noted above, the Supreme Court has also recognized that State requirements imposed on motor vehicle manufacturers, including sanctions imposed by State tort law, can stand as an obstacle to the accomplishment and execution of a NHTSA safety standard. When such a conflict is discerned, the Supremacy Clause of the Constitution makes the State requirements unenforceable. See Geier v. American Honda Motor Co., 529 U.S. 861 (2000).

   NHTSA does not believe that such conflicts are likely to arise from today's rulemaking, because this final rule only results in an administrative rewrite of the existing requirements of FMVSS No. 108. However, if such a conflict were to become evident, NHTSA may opine on such conflicts in the future, if warranted. See id. at 883-86.

5. Executive Order 12988 (Civil Justice Reform)

   With respect to the review of the promulgation of a new regulation, section 3(b) of Executive Order 12988, ``Civil Justice Reform,'' requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect; (2) clearly specifies the effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct, while promoting simplification and burden reduction; (4) clearly specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under guidelines issued by the Attorney General. This document is consistent with that requirement. Pursuant to this Order, NHTSA notes as follows. The preemptive effect of this rule is discussed above. NHTSA notes further that there is no requirement that individuals submit a petition for reconsideration or pursue other administrative proceeding before filing suit in court.

6. Executive Order 13045 (Protection of Children From Environmental Health and Safety Risks)

   Executive Order 13045, ``Protection of Children from Environmental Health and Safety Risks,'' applies to any rule that: (1) Is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an environmental, health, or safety risk that the agency has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the agency.

   This final rule is not subject to E.O. 13045 because it is not an economically significant regulatory action under Executive Order 12866, and because it does not involve decisions based upon health and safety risks that disproportionately affect children.

7. Paperwork Reduction Act

   Under the Paperwork Reduction Act of 1995 (PRA), a person is not required to respond to a collection of information by a Federal agency unless the collection displays a valid OMB control number. This final rule does not contain any collection of information requirements requiring review under the PRA.

8. National Technology Transfer and Advancement Act

   Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, (15 U.S.C. 272) directs the agency to evaluate and use voluntary consensus standards in its regulatory activities unless doing so would be inconsistent with applicable law or is otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies, such as the Society of Automotive Engineers. The NTTAA directs us to provide Congress (through OMB) with explanations when we decide not to use available and applicable voluntary consensus standards. The NTTAA does not apply to symbols.

   [[Page 68266]]

   This final rule does not adopt or reference any new industry or consensus standards that were not already present in Standard No. 108 (although in several cases, relevant requirements from such standards are now included directly in the standard, rather than being incorporated by reference). The agency's statements regarding the rationale for the use (or non-use) of information from third-party standards, as presented in prior rulemakings, remain unchanged.

   I. Unfunded Mandates Reform Act

   Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) requires Federal agencies to prepare a written assessment of the costs, benefits, and other effects of proposed or final rules that include a Federal mandate likely to result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector, of more than $100 million annually (adjusted for inflation with base year of 1995 (so currently $126 million in 2006 dollars)). Before promulgating a NHTSA rule for which a written statement is needed, section 205 of the UMRA generally requires the agency to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows the agency to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the agency publishes with the final rule an explanation of why that alternative was not adopted.

   This final rule is not anticipated to result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector in excess of $112 million annually. Instead, the cost impact of this administrative rewrite of Standard No. 108 is expected to be $0, because it does not change or increase the cost of existing requirements. Therefore, the agency has not prepared an economic assessment pursuant to the Unfunded Mandates Reform Act.

10. National Environmental Policy Act

    NHTSA has analyzed this rulemaking action for the purposes of the National Environmental Policy Act. The agency has determined that implementation of this action would not have any significant impact on the quality of the human environment.

11. Regulatory Identifier Number (RIN)

    The Department of Transportation assigns a regulation identifier number (RIN) to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. You may use the RIN contained in the heading at the beginning of this document to find this action in the Unified Agenda.

   S10.18.8.2 Aiming instructions.

   S10.18.8.2.1 The instructions for properly aiming the headlighting system using the VHAD must be provided on a label permanently affixed to the vehicle adjacent to the VHAD, or in the vehicle operator's manual. The instructions must advise that the headlighting system is properly aimed if the appropriate vertical plane (as defined by the vehicle manufacturer) is perpendicular to both the longitudinal axis of the vehicle, and a horizontal plane when the vehicle is on a horizontal surface, and the VHAD is set at ``0'' vertical and ``0'' horizontal.

   S10.18.8.2.2 Should a remote indicator or a remote indicator and adjuster be provided, the instructions must be placed in the operator's manual, and may also be placed on a label adjacent to the VHAD.

   S10.18.8.3 Permanent calibration. Each headlamp equipped with a VHAD must be manufactured with its calibration permanently fixed by its manufacturer. Calibration in this case means the process of accurately aligning the geometry of the VHAD devices with the beam pattern for the purposes of compliance with the standard.

When tested according to the procedure of S14.2.5 with any replacement headlamp unit(s) or light sources intended for use in the system under test, the VHAD and headlighting system must be designed to conform to the photometric performance requirements applicable for the system under test.

   S10.18.8.5 Physical tests. Each VHAD must be designed to conform with the performance requirements of S14.8.

   S10.18.9 Visual/optical aiming. Each visually/optically aimable headlamp must be designed to conform to the following requirements:

   S10.18.9.1 Vertical aim, lower beam. Each lower beam headlamp must have a cutoff in the beam pattern. It may be either on the left side or the right side of the optical axis, but once chosen for a particular headlamp system's design, the side chosen for the cutoff must not be changed for any headlamps intended to be used as replacements for those system's headlamps.

   S10.18.9.1.1 Vertical position of the cutoff. The headlamp must be aimed vertically so that the cutoff is on the left side, at 0.4[deg] down from the H-H line, or on the right side, at the H-H line.

   S10.18.9.1.4 Maximum inclination of the cutoff. The vertical location of the highest gradient at the ends of the minimum width must be within 0.2[deg] of the vertical location of the maximum gradient measured at the appropriate vertical line (at either 2.5[deg] L for a left side cutoff, or 2.0[deg] R for a right side cutoff).

   S10.18.9.1.5 Measuring the cutoff parameter.

   S10.18.9.1.5.1 The headlamp is mounted on a headlamp test fixture which simulates its actual design location on any vehicle for which the headlamp is intended. The fixture, with the headlamp installed, is attached to the goniometer table in such a way that the fixture alignment axes are coincident with the goniometer axes. The headlamp is energized at the specified test voltage. The cutoff parameter must be measured at a distance of 10 m from a photosensor with a 10 mm diameter.

   S10.18.9.1.5.2 The headlamp beam pattern is aimed with the cutoff at the H-H axis. There is no adjustment, shimming, or modification of the horizontal axis of the headlamp or test fixture, unless the headlamp is equipped with a VHAD. In this case the VHAD is adjusted to zero.

   S10.18.9.1.5.3 A vertical scan of the beam pattern is conducted for a headlamp with a left side gradient by aligning the goniometer on a vertical line at 2.5[deg] L and scanning from 1.5[deg] U to 1.5[deg] D. For a headlamp with a right side gradient, a vertical scan of the beam pattern is conducted by aligning the goniometer on a vertical line at 2.0[deg] R and scanning from 1.5[deg] U to 1.5[deg] D.

   S10.18.9.1.5.4 Determine the maximum gradient within the range of the scan by using the formula: G = log E(a)-logE(a + 0.1), where ``G'' is the gradient, ``E'' is illumination and ``a'' is vertical angular position. The maximum value of the gradient ``G'' determines the vertical angular location of the cutoff. Perform vertical scans at 1.0[deg] L and R of the measurement point of the maximum gradient to determine the inclination.

   S10.18.9.2 Horizontal aim, lower beam. There is no adjustment of horizontal aim unless the headlamp is equipped with a horizontal VHAD. If the headlamp has a VHAD, it is set to zero.

   S10.18.9.3 Vertical aim, upper beam.

   S10.18.9.3.1 If the upper beam is combined in a headlamp with a lower beam, the vertical aim of the upper beam must not be changed from the aim set using the procedures of S10.18.9.1 and S10.18.9.2 used for the lower beam.

   S10.18.9.3.2 If the upper beam is not combined in a headlamp with a lower beam, the vertical aim of the upper beam is adjusted so that the maximum beam intensity is located on the H-H axis.

   S10.18.9.4 Horizontal aim, upper beam.

   S10.18.9.4.1 If the upper beam is combined in a headlamp with a lower beam, the horizontal aim of the upper beam must not be changed from the aim set using the procedures of S10.18.9.1 and S10.18.9.2 used for the lower beam.

   S10.18.9.4.2 If the upper beam is not combined in a headlamp with the lower beam and has fixed horizontal aim or has a horizontal VHAD, then the headlamp is mounted on a headlamp test fixture which simulates its actual design location on any vehicle for which the headlamp is intended. The fixture, with the headlamp installed, is attached to the goniometer table in such a way that the fixture alignment axes are

   [[Page 68287]]

   coincident with the goniometer axes. The headlamp must be energized at 12.8 0.20 mV. There is no adjustment, shimming, or modification of the horizontal axis of the headlamp or test fixture, unless the headlamp is equipped with a VHAD. In this case the VHAD is adjusted to zero.

   S10.18.9.4.3 If the upper beam is not combined in a headlamp with a lower beam, and it does not have a VHAD, the horizontal aim of the upper beam is adjusted so that the maximum beam intensity is located on the V-V axis.

   S10.18.9.5 Photometry. When tested according to the procedure of S14.2.5, a visually/optically aimable headlamp must be designed to conform to the lower beam requirements of columns; LB1V or LB2V of Table XIX-a, or LB3V of Table XIX-b, or LB4V of Table XIX-c.

   S10.18.9.6.1 The lens of a lower beam headlamp must be marked ``VOL'' if the headlamp is intended to be visually/optically aimed using the left side of the lower beam pattern. The lens of a lower beam headlamp must be marked ``VOR'' if the headlamp is intended to be visually/optically aimed using the right side of the lower beam pattern. The lens of a headlamp that is solely an upper beam headlamp and intended to be visually/optically aimed using the upper beam must be marked ``VO''.

   S10.18.9.6.2 The lens of each sealed beam or integral beam headlamp must be marked ``VOR'' if the headlamp is of a type that was manufactured before May 1, 1997, and if such headlamp type has been redesigned since then to be visually/optically aimable.

   S14.2.3.1 Mounting. Each reflex reflector is mounted for photometry

   [[Page 68289]]

   with the center of the reflex area at the center of goniometer rotation and at the same horizontal level as the source of illumination.

   [deg] K.

   S14.2.3.3 Measurement distance. The test distance is 30.5 m

   [100ft] .

   S14.2.3.4 Test setup The observation point is located directly above the source of illumination. The H-V axis of reflex reflectors is taken as parallel to the longitudinal axis of the vehicle for rear reflectors and perpendicular to a vertical plane passing through the longitudinal axis of the vehicle for side reflectors.

   S14.2.3.7.1 The observation angle is the angle formed by a line from the observation point to the center of the reflector and a second line from the center of the reflector to the source of illumination.

   S14.2.3.7.2 The entrance angle is the angle between the axis of the reflex reflector and a line from the center of the reflector to the source of illumination.

   S14.2.3.7.3 The entrance angle is designated left, right, up, and down in accordance with the position of the source of illumination with respect to the axis of the reflex reflector as viewed from behind the reflector.

   S14.2.3.7.4 Measurements are made of the luminous intensity which the reflex reflector is projecting toward the observation point and the illumination on the reflex reflector from the source of illumination.

   S14.2.3.8 Measurements.

   S14.2.3.8.1 Reflex reflectors. The required measurement for reflex reflectors at each test point as shown in Table XVI is the quotient of the projected luminous intensity divided by the illumination expressed as millicandela per lux or candela per footcandle.

   S14.2.3.8.2 Retroreflective sheeting. The required measurement for retroreflective sheeting reflectors at each test point as shown in Table XVI is candela per lux per square meter of area.

   S14.2.3.8.3 Reflex reflector photometry measurement adjustments.

   S14.2.3.8.3.1 Reflex reflectors, which do not have a fixed rotational position on the vehicle, are rotated about their axis through 360[deg] to find the minimum photometric value which must be reported for each test point. If the output falls below the minimum requirement at any test point, the reflector is rotated 5[deg] about its axis from the angle where the minimum output occurred, and the maximum value within this angle is reported as a tolerance value.

   S14.2.3.8.3.2 Reflex reflectors, which by their design or construction, permit mounting on a vehicle in a fixed rotational position, are tested in this position. A visual locator, such as the word TOP is not considered adequate to establish a fixed rotational position on the vehicle.

   S14.2.3.8.3.3 If uncolored reflections from the front surface interfere with photometric readings at any test point, additional readings are taken 1[deg] above, below, right, and left of the test point, and the lowest of these readings and its location is reported provided the minimum test point requirement for the test point is met.

   S14.2.4 Daytime running lamp (DRL) photometry measurements.

   S14.2.5.7.2 Sensor.

   S14.2.5.7.2.1 The maximum effective area of the photometric sensor must fit within a circle whose diameter is equal to 0.009 times the actual test distance from the light source of the sample headlamp to the sensor.

   S14.2.5.7.2.2 The sensor effective area is defined as the actual area of intercepted light striking the detector surface of the photometer. Sensor systems incorporating lens(es) that change the diameter of the intercepted light beam before it reaches the actual detector surface, the maximum size requirements must apply to the total area of the light actually intercepted by the lens surface.

   S14.2.5.7.2.3 The sensor must be capable of intercepting all direct illumination from the largest illuminated dimension of the sample lamp at the test distance.

Standard Observer (2-degree) Photopic Response Curve, as shown in the C.I.E. 1931 Chromaticity Diagram (incorporated by reference, see 571.108 S5.2 of this title).

   S14.2.5.8 Location of test points.

   S14.2.5.8.1 Test point positions are defined by the positioner. The following nomenclature applies:

   S14.2.5.8.1.3 Horizontal angles designated L and R are defined as the plan view angle between the vertical plane and the projection of the light ray from the headlamp onto the horizontal plane.

   S14.2.5.8.1.4 Vertical angles designated U and D are defined as the true angle between the horizontal plane and the light ray from the headlamp.

   S14.2.5.9 Beam contributor photometry measurements. In a headlighting system where there is more than one beam contributor providing a lower beam, and/or more than one beam contributor providing an upper beam, each beam contributor must be designed to meet only the applicable photometric performance requirements based upon the following mathematical expression: conforming test point value = 2(test point value)/total number of lower or upper beam contributors for the vehicle, as appropriate.

   S14.4.1.4.1.2 A sphere may be used to integrate light from a colored source provided that the color shift that results from the spectral selectivity of the sphere paint be corrected by the use of a filter, correction factor, or an appropriate calibration.

   S14.4.1.4.1.3 Where the sample device does not have uniform spectral characteristics in all useful directions, color measurements must be made at as many directions of view as are required to evaluate the color for those directions that apply to the end use of the device.

   y = 0.33 (yellow boundary) y = 0.98 - x (purple boundary)

   S14.4.1.4.2.2 Yellow (Amber). The color of light emitted must fall within the following boundaries:

   y = 0.39 (red boundary) y = 0.79 - 0.67x (white boundary) y = x - 0.12 (green boundary)

   S14.4.2.1.3 Samples must be furnished in thicknesses of 1.6 0.25 mm, 2.3 0.25 mm, 3.2 0.25 mm, and 6.4 0.25 mm.

   S14.4.2.1.4 All samples must conform to the applicable color test requirement of this standard prior to testing.

   S14.4.2.1.5 A control sample, kept properly protected from influences which may change its appearance and properties of each thickness, must be retained.

   S14.4.2.2 Outdoor exposure test.

   S14.4.2.2.1 Outdoor exposure tests of 3 years in duration must be made on samples of all materials, including coated and uncoated versions, used for optical parts of devices covered by this standard. Tests are to be conducted in Florida and Arizona.

   S14.4.2.2.2 Concentrations of polymer components and additives used in plastic materials may be changed without outdoor exposure testing provided the changes are within the limits of composition represented by higher and lower concentrations of these polymer components and additives previously tested to this section and found to meet its requirements.

   S14.4.2.2.3 Procedure.

   S14.4.2.2.3.1 One sample of each thickness of each material must be mounted at each exposure site so that at least a minimum uninterrupted area of 32 sq cm of the exposed upper surface of the sample is at an angle of 45[deg] to the horizontal facing south. The sample must be mounted in the open no closer than 30 cm (11.8 in) to its background.

   S14.4.2.2.3.2 During the exposure time the samples must be cleaned once every three months by washing with mild soap or detergent and water, and then rinsing with distilled water. Rubbing must be avoided.

A new, unused abrading pad constructed of 0000 steel wool not less than 2.5 .1 cm wide, rubber cemented to a rigid base shaped to the same vertical contour of the lens, is used for each test. The abrading pad support is equal in size to the pad and the center of the support surface is within 2 mm of parallel to the lens surface. The ``grain'' of the pad is oriented perpendicular to the direction of motion. The density of the pad is such that when the pad is resting unweighted on the lens, the base of the pad is no closer than 3.2 mm to the lens at its closest point.

   S14.6.1.1.2 Abrading pad alignment. A sample headlamp is mounted in the abrasion test fixture of Figure 5 with the lens facing upward. When mounted on its support and resting on the lens of the test headlamp, the abrading pad is then weighted such that a pad pressure of 14 1 KPa. exists at the center and perpendicular to the face of the lens.

   S14.6.1.1.3 Abrasion test procedure. The pad is cycled back and forth (1 cycle) for 11 cycles at 4 0.8 in (10 2 cm) per second over at least 80% of the lens surface, including all the area between the upper and lower aiming pads, but not including lens trim rings and edges. A pivot must be used if it is required to follow the contour of the lens.

   (e) Antifreeze (50% concentration of ethylene glycol/distilled water by volume).

   S14.6.2.1.2 Fluid application. The entire exterior lens surface of the sample headlamp mounted in the headlamp test fixture and top surface of the lens-reflector joint is wiped once to the left and once to the right with a 6 inch square soft cotton cloth (with pressure equally applied) which has been saturated once in a container with 2 ounces of five different test fluids listed above. The lamp is wiped within 5 seconds after removal of the cloth from the test fluid. A new lamp sample may be used with each fluid.

   S14.6.2.1.3 Test duration. After the headlamp sample has been wiped with the test fluid, it must be stored in its designed operating attitude for 48 hours at a temperature of 23[deg]C 4[deg]C and a relative humidity of 30% 10%. At the end of the 48- hour period, the headlamp is wiped clean with a soft dry cotton cloth and visually inspected.

A sample headlamp, mounted on a headlamp test fixture in designed operating position and including all accessory equipment necessary to operate in its normal manner, is subjected to a salt spray (fog) test in accordance with ASTM B117-73, Method of Salt Spray (Fog) Testing (incorporated by reference, see 571.108 S5.2 of this title), for 50 total hours, consisting of two periods of 24 hours exposure followed by a 1 hour drying period. If a portion of the device is completely protected in service, that portion is covered to prevent salt fog entry during exposure. After removal from the salt spray and the final 1 hour drying period the sample headlamp is examined for corrosion that affect any other applicable tests contained in S14.6. If such corrosion is found, the affected test(s) must be performed on the corrosion sample and the results recorded.

   S14.6.3.2 Performance requirements. After completion of the corrosion test, the sample headlamp must not have any observed corrosion which would result in the failure of any other applicable tests contained in S14.6 and no corrosion of the headlamp mounting and aiming mechanism that would result in the failure of the aiming adjustment tests, inward force test, or torque deflection test of S14.6.

   S14.6.4 Corrosion-connector test.

   S14.6.4.1 Procedure.

   S14.6.4.1.1 A headlamp connector test must be performed on each filament circuit of the sample headlamp prior to the test in S14.6.4.1.2 according to Figure 4 and S14.6.15. The power source is set to provide 12.8 volts and the resistance must be set to produce 10 amperes.

   S14.6.4.1.2 The headlamp, with connector attached to the terminals, unfixtured and in its designed operating attitude with all drain holes, breathing devices or other designed openings in their normal operating positions, is subjected to a salt spray (fog) test in accordance with ASTM B117-73, Method of Salt Spray (Fog) Testing (incorporated by reference, see 571.108 S5.2 of this title), for 240 hours, consisting of ten successive 24-hour periods.

   S14.6.4.1.3 During each period, the headlamp is mounted in the middle of the chamber and exposed for 23 hours to the salt spray. The spray is not activated during the 24th hour. The bulb is removed from the headlamp and from the test chamber during the one hour of salt spray deactivation and reinserted for the start of the next test period, at the end of the first and last three 23-hour periods of salt spray exposure, and at the end of any two of the fourth through seventh 23-hour periods of salt-spray exposure.

   S14.6.4.1.4 The test chamber is closed at all times except for a maximum of 2 minutes which is allowed for removal or replacement of a bulb during each period.

   S14.6.4.1.5 After the ten periods, the lens-reflector unit without the bulb must be immersed in deionized water for 5 minutes, then secured and allowed to dry by natural convection only.

   S14.6.4.1.6 Using the voltage, resistance and pre-test set up of S14.6.4.1.1 the current in each filament circuit must be measured after the test conducted in S14.6.4.1.2.

   S14.6.5 Dust test.

   S14.6.5.1 Procedure.

   S14.6.5.1.1 A sample headlamp, mounted on a headlamp test fixture, with all drain holes, breathing devices or other designed openings in their normal operating positions, is positioned within a cubical box, with inside measurements of 900 mm on each side or larger if required for adequate wall clearance (i.e., a distance of at least 150 mm between the headlamp and any wall of the box).

   S14.6.5.1.2 The box contains 4.5 kg of fine powdered cement which conforms to the ASTM C150-77, Standard Specification for Portland Cement (incorporated by reference, see 571.108 S5.2 of this title). Every 15 minutes, the cement is agitated by compressed air or fan blower(s) by projecting blasts of air for a two-second period in a downward direction so that the cement is diffused as uniformly as possible throughout the entire box.

   S14.6.5.1.3 This test is continued for five hours after which the exterior surfaces of the headlamp are wiped clean.

   S14.6.5.2 Performance requirements. After completion of the dust test, the sample headlamp must meet the requirements of the applicable photometry tests of Table XIX and Table XVIII. A \1/4\[deg] reaim is permitted in any direction at any test point.

   S14.6.6 Temperature cycle test and internal heat test.

   S14.6.6.1 Samples. A sample headlamp with one or more replaceable light sources is tested according to the procedures of this section for a temperature cycle test and an internal heat test. The same sample headlamp is used in the temperature cycle test and then in the internal heat test.

   S14.6.6.2 General procedure.

   [[Page 68294]]

   S14.6.6.2.1 Tests are made with all filaments lighted at design voltage that are intended to be used simultaneously in the headlamp and which in combination draw the highest total wattage. These include but are not limited to filaments used for turn signal lamps, fog lamps, parking lamps, and headlamp lower beams lighted with upper beams when the wiring harness is so connected on the vehicle.

   S14.6.6.2.2 If a turn signal is included in the headlamp assembly, it is operated at 90 flashes a minute with a 75% 2% current ``on time.''

   S14.6.6.2.3 If the lamp produces both the upper and lower beam, it is tested in both the upper beam mode and the lower beam mode under the conditions above described, except for a headlamp with a single type HB1 or type HB2 light source.

   S14.6.6.3 Temperature cycle test.

   S14.6.6.3.1 Procedure.

   S14.6.6.3.1.1 A sample headlamp, mounted on a headlamp test fixture, is subjected to 10 complete consecutive cycles having the thermal cycle profile shown in Figure 6.

   S14.6.6.3.1.2 During the hot cycle, the lamp, is energized commencing at point ``A'' of Figure 6 and de-energized at point ``B.''

   S14.6.6.3.1.3 Separate or single test chambers may be used to generate the environment of Figure 6.

   S14.6.6.3.1.4 All drain holes, breathing devices or other openings or vents of the headlamps are set in their normal operating positions.

   S14.6.6.3.2 Performance requirements. After completion of the temperature cycle test, the sample headlamp must:

   (a) show no evidence of delamination, fractures, entry of moisture, or deterioration of bonding material, color bleeding, warp or deformation visible without magnification;

   (c) meet the requirements of the applicable photometry tests of Table XIX and Table XVIII. A \1/4\[deg] reaim is permitted in any direction at any test point.

   S14.6.6.4 Internal heat test.

   S14.6.6.4.1 Procedure.

   S14.6.6.4.1.1 A sample headlamp lens surface that would normally be exposed to road dirt is uniformly sprayed with any appropriate mixture of dust and water or other materials to reduce the photometric output at the H-V test point of the upper beam (or the \1/2\[deg]D-1\1/ 2\[deg]R test point of the lower beam as applicable) to 25% 2% of the output originally measured in the applicable photometric compliance test.

   S14.6.6.4.1.2 A headlamp with a single type HB1 or type HB2 light source is tested on the upper beam only.

   S14.6.6.4.1.3 Such reduction is determined under the same conditions as that of the original photometric measurement.

   S14.6.6.4.1.4 After the photometric output of the lamp has been reduced as specified above, the sample lamp and its mounting hardware must be mounted in an environmental chamber in a manner similar to that indicated in Figure 7 ``Dirt/Ambient Test Setup.''

   S14.6.6.4.1.5 The headlamp is soaked for one hour at a temperature of 35[deg] + 4[deg] - 0 [deg]C) and then the lamp is energized according to the procedure of this section for one hour in a still air condition, allowing the temperature to rise from the soak temperature.

   S14.6.6.4.1.6 At the end of one hour the sample lamp is returned to a room ambient temperature of 23[deg] + 4[deg] - 0 [deg]C and a relative humidity of 30% 10% and allowed to stabilize to the room ambient temperature. The lens is then cleaned.

   S14.6.6.4.2 Performance requirements. After completion of the temperature cycle test and meeting its requirements, and completion of the internal heat test, the sample headlamp must:

   (a) have no lens warpage greater than 3 mm when measured parallel to the optical axis at the point of intersection of the axis of each light source with the exterior surface of the lens, and

   (b) meet the requirements of the applicable photometry tests of Table XIX and Table XVIII. A \1/4\[deg] reaim is permitted in any direction at any test point.

   S14.6.7 Humidity test.

   S14.6.7.1 Procedure.

   S14.6.7.1.1 The test fixture consists of a horizontal steel plate to which three threaded steel or aluminum rods of \1/2\ inch diameter are screwed vertically behind the headlamp.

   S14.6.7.1.2 The sample headlamp assembly is clamped to the vertical rods, which are behind the headlamp. All attachments to the headlamp assembly are made behind the lens and vents or openings, and are not within 2 inches laterally of a vent inlet or outlet.

   S14.6.7.1.3 The mounted headlamp assembly is oriented in its design operating position, and is placed in a controlled environment at a temperature of 100[deg] + 7[deg]-0[deg] F (38[deg] + 4[deg]-0[deg] C) with a relative humidity of not less than 90%. All drain holes, breathing devices, and other openings are set in their normal operation positions for all phases of the humidity test.

   S14.6.7.1.4 The headlamp is subjected to 24 consecutive 3-hour test cycles. In each cycle, the headlamp is energized for 1 hour at design voltage with the highest combination of filament wattages that are intended to be used, and then de-energized for 2 hours. If the headlamp incorporates a turn signal then the turn signal flashes at 90 flashes per minute with a 75% 2% current ``on-time.''

   S14.6.7.1.5 Within 3 minutes after the completion of the 24th cycle, the air flow test will begin. The following procedure shall occur: the mounted assembly is removed, placed in an insulating box and covered with foam material so that there is no visible air space around the assembly; the box is closed, taken to the air flow test chamber, and placed within it. Inside the chamber, the assembly with respect to the air flow, is oriented in its design operating position. The assembly is positioned in the chamber so that the center of the lens is in the center of the opening of the air flow entry duct during the test. The headlamp has at least 3 inches clearance on all sides, and at least 4 inches to the entry and exit ducts at the closest points. If vent tubes are used which extend below the lamp body, the 3 inches are measured from the bottom of the vent tube or its protection. The temperature of the chamber is 73[deg] + 7[deg] - 0 [deg]F (23[deg] + 4[deg] - 0 [deg]C) with a relative humidity of 30% + 10% - 0%. The headlamp is not energized.

   S14.6.7.1.6 Before the test specified in paragraph S14.6.7.1.7 of this section, the uniformity of the air flow in the empty test chamber at a plane 4 inches downstream of the air entry duct is measured over a 4 inch square grid. The uniformity of air flow at each grid point is 10% of the average air flow specified in paragraph S14.6.7.1.7 of this section.

   S14.6.7.1.7 The mounted assembly in the chamber is exposed, for one hour, to an average air flow of 330 +0 -30 ft/min as measured with an air velocity measuring probe having an accuracy of 3% in the 330 ft/min range. The average air flow is the average of the velocity recorded at six points around the perimeter of the lens. The six points are determined as follows: At the center of the lens, construct a horizontal plane. The first two points are located in the plane, 1 inch outward from the intersection of the plane and each edge of the lens. Then, trisect the distance between these two points and construct longitudinal vertical planes at the two intermediate locations formed by the

   [[Page 68295]]

   trisection. The four remaining points are located in the vertical planes, one inch above the top edge of the lens, and one inch below the bottom edge of the lens.

   S14.6.7.1.8 After one hour, the headlamp is removed and inspected for moisture.

   S14.6.7.2 Performance requirements. After completion of the humidity test, the sample headlamp must show no evidence of interior delamination or moisture, fogging or condensation visible without magnification.

   S14.6.8 Vibration test.

   S14.6.8.1 Samples. The mounting bracket with a sample headlamp installed must not have a resonant frequency in the 10-55 Hz. range.

   S14.6.8.2 Procedure. The mounted sample headlamp is bolted to the anvil end of the table of the vibration test machine of Figure 21 and vibrated 750 cpm through a distance of 1/8 in. The table is spring mounted at one end and fitted with steel calks on the underside of the other end. The table is of sufficient size to completely contain the test fixture base with no overhang. The calks are to make contact with the steel anvil once during each cycle at the completion of the fall. The rack is operated under a spring tension of 60 to 70 lb. The vibration is applied in the vertical axis of the headlamp as mounted on the vehicle. Bulb filaments are not energized during the test. The test is continued for 1 hour.

   S14.6.8.3 Performance requirements. After completion of the vibration test, there must be no evidence of loose or broken parts, other than filaments, visible without magnification.

   S14.6.9 Sealing test.

   S14.6.9.1 Procedure.

   S14.6.9.1.1 An unfixtured sample headlamp in its design mounting position is placed in water at a temperature of 176[deg] 5[deg] F (60[deg] 3[deg] C) for one hour. The headlamp is energized in its highest wattage mode, with the test voltage at 12.8 0.1V during immersion.

   S14.6.9.1.2 The lamp is then de-energized and immediately submerged in its design mounting position into water at 32[deg] +5[deg] -0[deg] F (0[deg] +3[deg] -0[deg] C). The water is in a pressurized vessel, and the pressure is increased to 10 psi (70 kPa), upon placing the lamp in the water. The lamp must remain in the pressurized vessel for a period of thirty minutes.

   S14.6.9.1.3 This entire procedure is repeated for four cycles.

   S14.6.9.1.4 Then the lamp is inspected for any signs of water on its interior. During the high temperature portion of the cycles, the lamp is observed for signs of air escaping from its interior.

   S14.6.9.2 Performance requirements. After completion of the sealing test, a sample headlamp confirmed to be sealed need not meet the corrosion test, dust test, or humidity test of this Section. If any water is on the interior or air escapes, the lamp is not a sealed lamp.
