I got some led on fog lamps. Better than halogen but no better than xenon. Use them once on fog and did work on visivilty
are you talking about led headlamps or halogen base led bulb? first work ok, but worse than hid, there is still no headlamp to match the hid, not eaven laser headlights from bmw. second is garbage and should be avoided led light create to much of a foreground which reduces distant vision.
