Those Glaring Headlights on the Highway Could Be Illegal Soon, Regulators Say
The new rule allows headlamps that steer light away from oncoming traffic and could reduce nighttime glare, officials said.
On Tuesday, the National Highway Traffic Safety Administration announced it will rewrite federal vehicle lighting standards to address growing glare complaints and allow automakers to adopt newer lighting technologies.
Federal brightness standards have not changed since 1997, while complaints about glare have intensified as brighter LEDs and a growing share of tall SUVs on roads replaced traditional halogen bulbs.
Transportation Secretary Sean Duffy will appoint 18 stakeholders to guide a "negotiated rulemaking" process, with public comments accepted until November 9, 2026.
The agency aims to harmonize U.S. regulations with international safety standards while evaluating adaptive driving beams, dusk sensors, and automatic high beams to steer light away from oncoming traffic.
While the 2022 rules failed to enable widespread adaptive beam adoption due to overly restrictive requirements, this updated approach seeks to finally unlock safety-improving lighting technologies for American roads.
