Do oncoming headlights bother you enough at night to be a safety concern?

Headlights have grown brighter and harsher over the past decade as automakers shift to LED bulbs and mount lights higher on taller vehicles. NHTSA has announced plans to modernize its lighting safety rules and study beam patterns and glare, and is accepting public feedback on its proposal through November 9.

Why it matters

Roughly 6 in 10 drivers cite nighttime glare as a major safety concern and say it has worsened significantly over the past decade, which affects anyone who drives after dark, including families with teen drivers and older relatives. Glare is a daily comfort and safety issue for U.S. households even though headlight glare accounts for only a fraction of nighttime collisions.

Only 5% of 2026 model-year vehicles were flagged for excessive glare during testing, down from 21% of vehicles in 2017. NHTSA is accepting public comments on its proposal through November 9.

The players

National Highway Traffic Safety Administration (NHTSA)

The federal agency that sets and enforces U.S. vehicle safety standards, including the lighting rules now under review.

The details

Many automakers have moved to LED headlights, which emit a crisp white-blue light that the human eye perceives as harsher than the warmer glow of older halogen bulbs. Headlights are also mounted higher as buyers shift toward taller trucks and SUVs, which places the beam closer to the eye level of oncoming drivers. Automakers are responding by lowering the physical placement of high-intensity projector lenses, and NHTSA plans to study beam patterns and glare intensity as part of modernizing its lighting safety rules.

Timeline

  1. 2017: 21% of vehicles were flagged for excessive glare in testing.

  2. Past 10 years: headlight intensity and glare steadily increased.

  3. 2026 model year: only 5% of vehicles were flagged for excessive glare.

  4. November 9: deadline for public feedback on NHTSA's proposal.

The Home Front

NHTSA's planned rulemaking on beam patterns and glare marks a formal federal response to a shift that began as automakers adopted LED headlights across their vehicle lineups. The 21% to 5% drop in glare-flagged vehicles between 2017 and the 2026 model year shows the testing trend has moved in the opposite direction from driver complaints.

If you drive at night and find oncoming headlights uncomfortable, consider adjusting your own mirror and seat position so your eyes sit lower and away from the direct beam path. When shopping for a new vehicle, test-drive it after dark if you can, since glare is easiest to judge in real nighttime conditions.

The takeaway

Brighter, higher-mounted headlights are now a shared issue for drivers across the country, and the federal review is the place to watch how it changes. When comparing vehicles, a nighttime test drive gives you a more reliable read on glare than a spec sheet.

What happens next

NHTSA is accepting public feedback on its lighting proposal through November 9, the deadline for comments on the agency's plan to study beam patterns and glare.
