Relating to lighting equipment requirements for motor vehicles.
Summary
HB 4955 amends the Texas Transportation Code to clarify when a high-mounted stoplamp on a motor vehicle is treated as compliant with federal lighting standards. Specifically, the bill adds a new subsection stating that, for purposes of Section 547.3215, a high-mounted stoplamp complies with the referenced federal standard if, during braking for no more than two seconds, the lamp varies in intensity four or fewer times and does not fully deactivate.
The bill is narrowly focused on vehicle lighting equipment requirements and does not create a new regulatory program. Instead, it provides a statutory interpretation rule that aligns state compliance determinations with a specific federal lighting standard in 49 C.F.R. Section 571.108. The act takes effect September 1, 2025, and would affect vehicle manufacturers, aftermarket lighting suppliers, inspectors, law enforcement, and drivers subject to Texas motor vehicle equipment rules.
Impact
HB 4955 would modify Section 547.323 of the Transportation Code by adding a compliance clarification for high-mounted stoplamps. This change would affect how Texas applies vehicle lighting requirements under Section 547.3215, likely reducing ambiguity about whether certain stoplamp designs meet federal standards. The practical impact is limited to motor vehicle equipment compliance and enforcement, but it could influence inspection practices, vehicle design specifications, and citations involving brake light functionality.
Sentiment
The available legislative history suggests little controversy around the bill. It advanced through the House Transportation Committee and was reported to the Local & Consent Calendar, which typically indicates a measure viewed as routine or noncontroversial. No committee transcript or recorded vote information is provided, but the procedural path suggests general support or at least no significant opposition in committee.
Contention
No specific points of contention are documented in the provided materials. If any concerns existed, they would likely have centered on whether the state should codify a precise federal compliance standard for stoplamps and whether the language could affect enforcement discretion or vehicle equipment design. However, the bill’s narrow scope and committee disposition indicate that such issues were not prominent in the available record.
