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

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.
