Official title: Clarify certain regulations to allow for the installation of pulsating light systems for high-mounted stop lamps, and for other purposes.
Introduced July 15, 2025 by Thomas Roland Tillis · Last progress July 15, 2025
The bill accelerates adoption of pulsating high‑mounted stop lamps—potentially reducing rear‑end crashes and spurring innovation—but raises risks that some drivers will be confused, devices will be allowed before final rules exist, and costs could increase if standards are poorly specified.
Drivers and vehicle passengers may experience fewer rear-end crashes because high-mounted pulsating stop lamps can better attract attention during initial braking.
Vehicle manufacturers can proceed to install pulsating lamps without enforcement uncertainty, enabling faster real-world adoption of the safety technology.
A required regulatory update within 180 days creates a clear, performance‑based pathway for lighting innovation and future devices.
Some drivers and other roadway users may be startled or confused by pulsating brake lights, which could cause unsafe reactions and offset safety gains for certain populations.
Deeming devices compliant as of enactment creates a temporary regulatory gap where pulsating lamps are permitted before final performance rules are in place, risking inconsistent implementations and enforcement challenges.
If the new performance standards are poorly specified, vehicle manufacturing costs could rise and those costs may be passed on to consumers.
Based on analysis of 2 sections of legislative text.
Declares a defined pulsating high‑mounted stop lamp permissible under FMVSS No. 108 and requires DOT to adopt performance‑based rules allowing them within 180 days.
Allows a specific flashing pattern for a vehicle’s high‑mounted brake light (a “pulsating light system”) by declaring that the current Federal Motor Vehicle Safety Standard No. 108 (FMVSS 108) already permits its use and by instructing the Secretary of Transportation to issue regulations within 180 days to update Standard 108 with performance‑based requirements that expressly allow such systems. The law defines the permitted pulse timing and a lockout interval after braking, and sets a short statutory timeline for the Department of Transportation to adopt implementing rules.
