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

Riepilogo

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. These amendments will restore the side marker photometry requirements for motor vehicles under thirty 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.
