Headlight fuse

[JRZ2500HD]

does anyine know if each headlight hsa it's own fuse. i bought a wire harness from suvlights w/the diode in it. now the factory low beam wiring that was hooked up to the new harness does not work. anyone have any ideas?

IFf you send your truck to the dealer for headlight problems and have aftermarket lights, put the stock ones back in. They charged me $90 to diagnosis it because of the bulbs. And of course they say it's the bulbs, but all was well before the suvlight harness. Now i'm afraid to try the harness again, I don't want the same result. And suvlights have no idea why this would happen. So beware if you have a 2003 GM.

I dont know about your diode kit. My uncle has it, and it works great. What I did to mine though, to get all 4 lights to stay on, is cut the ground to the low beam bulb, and attach it to a real ground. the Trucks BCM (Body Control Module) turns the low beam's ground to positive power when the high beams are turned on.
