What this bill does
In plain words · AI-written from the official summaryAllows pulsating brake lights on vehicles
Right now, federal safety rules require brake lights to stay steady when you hit the brakes. This bill would change that rule to allow a new kind of brake light that pulses rapidly a few times before staying solid, similar to how some high-end cars already do. The Department of Transportation would need to write new regulations that set performance standards for these pulsating lights and allow them on cars, trucks, buses, and motorcycles.
How it affects you
If you drive or ride in vehicles, this could eventually mean you'll see pulsating brake lights on the road as more cars adopt this technology. Manufacturers say these lights might help other drivers notice when a vehicle is braking more quickly, though the official summary doesn't spell out what safety benefits this creates for you as a driver or passenger.

Collision Avoidance Systems Act of 2025
This bill allows for the use of a pulsating light system for vehicle braking.
Specifically, Federal Motor Vehicle Safety Standard Number 108 (Standard 108) must be deemed to allow for the use of a pulsating light system on covered vehicles (i.e., passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, and motorcycles). The Department of Transportation must issue regulations to update Standard 108 to (1) include performance-based standards for pulsating light systems, and (2) allow for the use of the systems on motor vehicles.
As background, Standard 108 regulates all automotive lighting, signaling, and reflective devices. Under the bill, a pulsating light system includes a system for a high-mounted stop lamp in which the lamp pulses rapidly no more than four times and for no more than 1.2 seconds when the brake of the vehicle is applied and then converts to a continuous light (as a normal stop lamp) until the brake is released.
