HB1361, titled the Collision Avoidance Systems Act of 2025, would amend the federal motor vehicle safety framework to expressly permit pulsating light systems for high-mounted stop lamps. The bill states that, beginning on enactment, Federal Motor Vehicle Safety Standard No. 108 is deemed to allow these systems on covered vehicles, and it directs the Secretary of Transportation to update the standard within 180 days with performance-based requirements.
The bill defines a pulsating light system as a high-mounted stop lamp that rapidly pulses up to four times for no more than 1.2 seconds when the brake is applied, then switches to a steady stop lamp until the brake is released. It also requires a lock-out period of at least five seconds before the pulsing sequence can repeat after brake release. In practical terms, the measure would create a clear federal pathway for manufacturers to install this type of rear lighting system as a collision-avoidance feature.
Impact
The bill would affect Federal Motor Vehicle Safety Standard No. 108, which governs vehicle lighting and related equipment, by clarifying that pulsating high-mounted stop lamps are permitted and by requiring the Department of Transportation to issue conforming regulations. Its main legal effect is to preempt uncertainty under existing federal vehicle lighting rules and to establish performance criteria for manufacturers, regulators, and potentially aftermarket or OEM safety systems. The bill does not create a new state program, but it would influence vehicle design and compliance nationwide because Standard 108 is a federal safety standard applied to motor vehicles.
Sentiment
Available context suggests generally favorable sentiment, with bipartisan sponsorship from members of both parties and no recorded votes or committee objections in the provided materials. The bill’s title and structure frame it as a safety-oriented clarification rather than a controversial regulatory expansion. Because there are no transcripts or vote tallies, there is no evidence in the record provided of organized opposition or support beyond the introduction itself.
Contention
The main potential point of contention is whether pulsating brake lights improve rear-end collision avoidance enough to justify changing long-standing lighting standards, or whether they could create confusion, inconsistency, or enforcement issues. Another likely issue is the balance between innovation and uniformity in vehicle safety regulation: supporters may view the bill as enabling a proven safety feature, while skeptics may question whether the federal standard should be amended to accommodate a specific lighting pattern. No specific objections are recorded in the provided committee or vote history.
