Why Modern Car Headlights Are Blinding Drivers More Than Ever

Growing complaints about blinding vehicle headlights have prompted US regulators to reconsider outdated lighting standards, as LED technology and the popularity of taller SUVs and trucks contribute to increased glare.

Experts say modern LED headlights produce harsher, bluer light, while higher-mounted lamps can shine directly into the eyes of drivers in smaller vehicles. A AAA survey found that six in 10 drivers consider nighttime headlight glare a problem. The National Highway Traffic Safety Administration is reviewing existing regulations and plans to consult experts and the public. Researchers argue that current testing methods fail to adequately account for real-world headlight positioning and alignment.

Adaptive driving beam technology, which automatically adjusts lighting using cameras and sensors, could help reduce glare. Meanwhile, recalls involving vehicles from General Motors, Subaru and Tesla highlight ongoing safety concerns. Despite persistent complaints, research by the Insurance Institute for Highway Safety found that glare-related nighttime crashes remained relatively stable between 2015 and 2023, accounting for one to two accidents per 1,000 nighttime crashes.
