    LED Headlights aren’t the problem. Are LED lightbulbs a billion times brighter than others? No. They make them use less power and are the same brightness. The problem is not using dimmer LEDs.

      It’s also the way they make cheap LED headlights. The reflectors that direct the beam of light in your headlights expects the filament of the bulb to be in a very specific spot, but LED headlights often have a much wider area where the light emits from than the little filament that traditional headlights do. So when installed in cars that aren’t designed for LEDs, the beam pattern can be off and make the light shine at people instead of down toward the road.

    Aren’t all lights led nowadays? I don’t think the type of the light is the problem

      exactly, LED lights aren’t magically bad, car regulations and enforcement of those regulations just suuuuuuuuuuuck.

      The only reason you couldn’t make incandescents as bad is because they’d fucking melt.

    Can someone who knows more about the engineering of these lights explain why they suck so much? It seems like them being LED rather than incandescent can’t be the whole story. I just want to be able to drive at night without being blinded every time a car comes through the opposing lane.

      LED headlights can be many times brighter than incandescent bulbs with no significant impact to life expectancy. Physically, incandescent bulbs produce light by heating up an element which decays relatively quickly. LEDs directly convert electricity to light.

      In the US, there ARE regulations limiting how bright headlights can be, but aftermarket LEDs can be bought which exceed the limit. I’ve heard the EU and Asia already widely use adaptive headlight technology so it’s a uniquely american car problem
