NHTSA to modernize U.S. vehicle lighting standards to address headlight glare

The National Highway Traffic Safety Administration (NHTSA) has announced plans to modernize Federal Motor Vehicle Safety Standard No. 108, the regulation governing automotive lighting. This marks the first major overhaul of U.S. vehicle-lighting standards in over 25 years.

The rulemaking process aims to address increasing motorist complaints regarding headlight glare, particularly from modern LED systems and taller vehicles. The review will examine several key areas, including LED technology, automatic high beams, dusk sensors, replaceable light sources, headlamp height and aim, and testing procedures. Additionally, the agency intends to work toward harmonizing American requirements with international standards.

Transportation Secretary Sean Duffy will appoint up to 18 representatives from various sectors—including lighting manufacturers, safety organizations, and research institutions—to participate in a negotiated rulemaking process. NHTSA Administrator Jonathan Morrison stated that current standards prevent automakers from deploying the latest safety-improving lighting technologies and emphasized a collaborative approach to foster innovation and safety.
