This bill directs the Secretary of Transportation, acting through the Administrator of the National Highway Traffic Safety Administration, to issue a final rule within one year of its enactment. This rule will revise Federal Motor Vehicle Safety Standard Number 108, which governs lamps, reflective devices, and associated equipment. The primary objective is to establish a maximum allowable brightness standard for low beam headlamps on motor vehicles, specifically to limit intense glare for highway and two-lane safety. The new standard must be expressed in lumens or another appropriate photometric measurement as determined by the Secretary. This legislative action aims to enhance road safety by addressing concerns related to excessively bright vehicle lighting.
