Wire it direct to the battery and see if it still does it.

Then its the circuit breaker tripping. The led should be drawing a lot less amps than factory fogs so either its bad or there is something screwy in the wiring. You could always wire fresh through a relay and use the factory wiring to switch the relay.

As suggested, use the stock factory wiring to operate a relay and wiring that you install for LED light.
