Comment glare means light is being wasted (Score 4, Interesting) 64
When bright headlights cause glare on the eyes of oncoming traffic that means that much of that bright light is not actually going where it would benefit the driver. While bright factory LEDs do cause glare, much of the problem seems to be from retrofitting halogen housings with LED. Such retrofits don't always actually improve things for the driver even if they look brighter. They are going to have to crack down on retrofit LED bulbs is they really want to tackle the issue.
