My headlights work fantastic since I installed a heavy duty headlight harness from LMC. It has two 30 amp relays and is a plug and play harness, for TF trucks. They have one for the AD trucks also. I had installed halogen headlights and they were overheating the stock circuit breaker on the headlight switch. The old stock headlights worked OK, but were dim , and it was not much fun driving on Calif freeways after dark. No more! It's like having two search lights on the front of my truck. I have them adjusted down and alittle to the right, so as to not blind oncoming drivers. Low beams are nice and bright too.
