Are LED Headlights Too Bright? Why Drivers Are Demanding Change
Studies reveal that LED headlights emit light more efficiently than traditional halogen bulbs, but this efficiency comes with downsides. Research from the RAC found that 89% of drivers in the UK believe headlights are “too bright,” with LED lights being the primary culprit. Moreover, 85% of those surveyed said the problem has worsened in recent years, with many drivers experiencing discomfort, delayed reaction times, and reduced visibility in oncoming traffic.
One study published in Frontiers in Public Health highlighted that poorly directed LED headlights can cause temporary “disability glare,” impairing the driver’s ability to see and respond to road hazards. The problem intensifies for those with pre-existing conditions like cataracts, where bright, high-intensity light creates halos or worsens night blindness.
Driver Frustrations: First-Hand Accounts of LED Glare
For countless drivers, the experience of facing LED headlights is not just an inconvenience—it’s a safety concern. Many report being temporarily blinded when facing oncoming traffic or driving in rain or fog. Some even avoid night driving altogether due to the discomfort. One driver shared that the brightness from oncoming trucks at a stoplight was so intense it felt like sitting in a “floodlit stadium.” Another noted the difficulty of driving on dark country roads where LED glare completely removes visibility.
The most common complaint is that these lights are often misaligned, especially on larger vehicles like SUVs and pickup trucks. Drivers of smaller sedans report that the higher positioning of headlights on taller vehicles shines directly into their line of sight, creating an unbearable glare. Others note that improperly installed LED retrofit kits in older vehicles scatter light in every direction, making the issue even worse.
What’s Causing the Problem?
Drivers aren’t just imagining the issue—LED headlights are up to 60% brighter than traditional halogen lights. While this brightness is great for illuminating the road ahead, it often causes:
- Blinding Glare: Many complain that LED lights appear as though the high beams are always on, even when they’re not.
- Misaligned Beams: Poor alignment exacerbates the issue, especially when headlights are mounted higher on SUVs and trucks, shining directly into the eyes of drivers in smaller cars.
- Harsh Blue-White Hue: The “cool” color temperature of many LED lights is particularly harsh on the eyes, especially for older drivers or those with pre-existing vision conditions.
One driver vented:
“SUVs and trucks are the worst offenders. Their headlights hit me right at eye level in my sedan. It’s blinding, and there’s nothing I can do to avoid it.”
