The National Highway Traffic Safety Administration (NHTSA) has initiated a rulemaking effort to modernize federal vehicle lighting standards, marking the first major review of these regulations since 1997.

The agency is investigating safety concerns regarding headlight glare, particularly how the transition from halogen to LED technology affects visibility. A significant focus of the review is the impact of taller vehicles, such as SUVs and lifted pickup trucks, whose headlights may shine directly into the eyes of drivers in lower vehicles. 

In addition to addressing glare, the NHTSA intends to examine headlight aiming, height, automatic high beams, and dusk sensors. The agency also aims to streamline testing procedures for materials like plastic optics and work toward aligning U.S. vehicle lighting regulations with international safety standards.
