    so last week I had broken my fog lights and now have a new set

    probblem is I cant figure out what is wrong with them and why they wont light up

    the only thing I have noticed is that on my switch it has a little light in it that turns on when you turn the switch to the on position that is not turning on so that might be some some indication of the probblem

    or the problem could be that the lights just suck and don't work... I don't know so any help would be appreciated and if pics are needed then I can get some

    Are they stock fog lights? or are they custom? I suggest you try working the fog lights without a switch, maybe by touching the wires together. Good luck

    Check for power to the switch, check your grounds, check for broken wires / blown fuses from when the other lights got broken.
    You can "bench test" the new lights by touching the wires across the battery - watch your eyes!

    Good luck,

    X2 on checking the lights directly off the battery, I had a set of PIAA lights that the LED indicator on the switch burned out (I didn't know that at the time) and I tore apart the whole truck only to find out that there was nothing wrong at all just a bad indicator light. A broken wire could be a possibility as well, if those two things are not messed up then the lights are probably bad.

    ok so we used the wiring and switch that came with the lights and it works just fine but it wont work with my existing wiring and relay

    I'm thinking its because the system has like a fuse box with a 20 amp fuse in it and there is no relay

    What kind of lights are these, because I know my PIAA's are funny about stuff like that as well. They come with there own terminated wiring harness, so you have to use what they give you instead of existing wiring. My KC's are just generic wiring with a fuse and relay, that is definatley interesting that it didn't work with the other wiring. Well at least this way you get to start off with new wiring, good luck with the new system.
