Simple Light Question

Bought a set of 100 watt off road lights off a buddy for $10, they are cheap ones but they were new in the box and I think the wrangler doesnt look right without lights on the front bumper. Anyways I wired them directly into the existing wiring for the lights that should be on the bumper (guess previous owner maybe broke one since the bumper was dented in and removed both of them) question is what wattage were the factory lights and will wiring in these 100 watt lights cause any problems to the factory wiring? Thanks

Stock are 55 watts.I'd be putting a relay on them and run a new switch.

Use a relay before you smoke the wiring.

Not just a relay but heavier wiring as well. The factory 55 watt fogs draw nearly 10 amps, the pair of 100 watt lights will draw approx. 16.6 amps.

If you want to get real fancy,put a fuse between the switch and the power source/ignition as well. That way it's protected on both sides.Thats how I've got mine, slightly more advanced than this diagram but you get the idea.

That probably wouldn't be necessary as by the diagram there wont be hardly any amp draw whatsoever at that point because the relay is handling the load.
