The Collision Avoidance Systems Act of 2025 says Federal Motor Vehicle Safety Standard Number 108 (Standard 108) allows the use of pulsating light systems on high-mounted stop lamps. The bill defines a pulsating light system: when the vehicle brake is applied, the lamp pulses rapidly no more than 4 times and for no more than 1.2 seconds, then stays on as a normal continuous stop lamp until the brake is released. The pulses may not repeat on a subsequent brake application for at least a 5-second lock-out period after the brake is released. The bill directs that, as of the date of enactment, Standard 108 is deemed to allow these systems. It also requires the Secretary of Transportation to issue regulations within 180 days to update Standard 108 to include performance-based standards for these pulsating light systems and to allow their use on covered vehicles.
If enacted, the bill makes clear that vehicle makers may install defined pulsating high-mounted brake lights. The Secretary of Transportation must write rules within 180 days to set performance-based standards and to formally allow these systems under Standard 108. The text does not provide other details about how or when manufacturers, dealers, or drivers must change vehicles.
