NHTSA amends side marker requirements for reflective devices

Restores requirements that were in place prior to 2007 final rule

Posted February 9, 2016

The National Highway Traffic Safety Administration (NHTSA) is amending the side marker requirements contained in the Federal Motor Vehicle Safety Standard (FMVSS) on lamps, reflective devices, and associated equipment for vehicles 80 inches or more in width and less than 30 feet long.

This final rule adopts the amendments proposed in the Notice of Proposed Rulemaking (NPRM), published on December 4, 2012, and addresses an unintentional change NHTSA made to the photometric requirements for side marker lamps when it reorganized FMVSS No. 108 in 2007. These amendments will restore the side marker photometry requirements for motor vehicles under 30 feet in length that were in place prior to the 2007 final rule that reorganized the standard.

Restoration of the side marker requirements will have no negative impact on safety or function and will allow motor vehicle manufacturers to avoid unnecessary modifications to their side marker lamps with no added safety or functional benefit.

The rule takes effect August 8, 2016, with optional early compliance. NHTSA states that providing early optional compliance will allow manufacturers to immediately benefit from the flexibility afforded by the revised side marker requirements.
