Electrical problem fog lights?
Make sure you have a fuse installed on the circuit. Check your car manual for which fuse.

don't forget they only work when the main lights are on so try them with your dipped headlights on...
If the vehicle wasn't equipped with them from the factory the harness is not complete, there is a harness specifically for the fog lamps as well as relays and wiring in the dash and fuse panel. So best thing is to have a certified mechanic install them properly to avoid any problems down the road
