My car passes inspection with them every 2 years, high beam and low. The problem is people looking for the cheapest, brightest bulbs possible, doing no research about optimal design for headlight style(reflector vs projector) and then not properly orienting the diodes or aiming the headlight properly. Spend a little extra money for a more well designed kit and they end up with no more glare than a luxury model car factory headlights, like mercedes, bmw, etc...
