S 2290 Re-checks Congress.gov for new actions and updates the bill's status, and fills in any sponsors, committees, or related bills that are missing. It does not re-pull sponsors/cosponsors/committees/related — those rarely change — and it skips all work if nothing has changed upstream, so it's cheap to click.
Collision Avoidance Systems Act of 2025
To clarify certain regulations to allow for the installation of pulsating light systems for high-mounted stop lamps, and for other purposes.
Summary
This bill clarifies and allows the use of pulsating light systems for high-mounted stop lamps on vehicles, effective immediately upon enactment. A pulsating light system is defined as a system that pulses rapidly up to four times for a maximum of 1.2 seconds when brakes are applied, then converts to continuous light until the brake is released, with at least a 5-second lock-out period before pulses can repeat. The bill requires the Secretary of Transportation to update Federal Motor Vehicle Safety Standard Number 108 within 180 days to include performance-based standards for pulsating light systems and officially allow their use on vehicles.
