I think Hella is the OEM for Jeep you might check them out. As long as you keep the same factory wattage you could use the factory wiring. If you go higher you will need to add a relay and use the factory wire as the switch signal.
I replaced my stock fog lights with 2 small led cubes. The lights aren't crazy bright, but they project nice white light, and their much better than the factory fogs, and the stock headlights. Their actually nice enough to drive with them on and the (lousy) oem headlights off. I have them running on the stock fog wiring with no issues.
