I tested it in my old cars and light is much better as halogen light. Color 3000K is really yellow - more then yellow , more little bit orange as natrium discharge lamps. This light make road details better visible. The lamp are solid made of metal not plastic material and fit to headlights bulb holder. I had to modify back headlights covers because these LED lamps have longer back compare to halogen bulbs.
The polarity is reversed so I don't know if they won't unplug themselves because the holding edge is on the other side but the light is nice.
