Allows the use of pulsating light systems for high-mounted stop lamps on vehicles.

The Collision Avoidance Systems Act of 2025 clarifies regulations to permit the installation of pulsating light systems for high-mounted stop lamps on vehicles. This system involves the lamp pulsing rapidly up to four times when the brake is applied, then converting to a continuous light until the brake is released. The bill mandates the Secretary of Transportation to issue regulations updating Standard 108 to include performance-based standards for these systems and to allow their use on motor vehicles within 180 days of the act's enactment.
