whats going on hope you can give me some help. I installed truck lite led headlights part number 27450c and its not switching back and forth with the fog lights and hi beams the way they normally do with regular bulbs.
Thank you Tommy

 

Check the headlamp socket for proper wiring. I had that problem when I 1st installed my halogen lights. The new lights have the ground on a different pin in the socket. If this is the case you will either have to change the pins in the socket to match the new light or get a harness that does it for you. If you do a search you can find the thread with the proper pin info.

 

Just put those exact lights in my car and had the exact issue, lol
I am horrible at that stuff, but will get my buddy who got them going to post what the fix was, lights work great now. I love the color and look, was weary of the price but I like them for sure.
