Bright, misaligned LED headlights cause dangerous glare for UK drivers, experts say.

Bright car headlights are causing increased glare for UK drivers at night, primarily due to brighter LED lights and misalignment. LEDs produce up to 200 lumens per watt—far more than older halogen bulbs—and emit a harsher, bluer light (5000K–6500K). Experts say improper beam aiming, especially lights pointing too high, worsens the issue. They recommend adjusting headlights by marking beam centers on a wall 5–7 meters away and lowering the beams slightly. Using rear-view mirror night mode also reduces glare from vehicles behind. Proper alignment is key to improving safety and comfort for all drivers.
