One kc fog light working
I wired my new 100w kc fog lights today and wired them the exact way I wired my windshield mounted kc driving lights several months ago, (with kc supplied relay and harness). One fog light does not burn. Any suggestions?

I unplugged the burning light into the non burning light and it works off that plug so its not a bulb issue

does your relay have 4 or 5 prongs? KC uses a 5 prong while hella and just about everybody else use a 4 and that will cause your problem. our work truck has 4 KC's on 2 relays. one of the relays went bad and all I can find are 4 prong so we only have 3 working lights.

It's 5 prong

it has to be either the relay itself or the wiring to that particular light. read out the relay with a multimeter.
