US Experts Say Headlights Aren't Bright Enough

An anonymous reader quotes a report from The Guardian: Complaints about the brightness of modern headlights have become commonplace. On X, thousands of users have tweeted about headlights being too bright. The subreddit r/fuckyourheadlights has over 35,000 members who post blurry photos of offending high beams and LED headlights. Outlets like the New York Times and NBC News have written about the risks of headlight glare. Advocacy groups have called for bans on LED headlights. And the UK government launched a review into the dangers of headlight glare earlier this year, after many driver complaints. And yet, according to many experts, the problem with headlights is not that they're too bright -- it's that they're not bright enough. "We actually need more light on the road than what we have," says Greg Bannon, director of automotive engineering at the American Automobile Association (AAA). Only a minority of US roadways have overhead street lighting, as one 2019 AAA report noted. As a result, in many areas, headlights are the sole method of illumination when driving at night. But which is the safety bigger risk: inadequate illumination, or headlights that impair the vision of other drivers? The report notes that the U.S. standards set by the National Highway Traffic Safety Administration (NHTSA) haven't changed in decades and are much weaker than Europe's. Adaptive headlights, which automatically adjust brightness to avoid blinding other drivers, have been approved by NHTSA since 2022 but are still relatively rare due to differing standards and costs.
