I have a heavy duty wireing harness upgrade with the bright light feature. It started with the driver side light going out, for about a week then mysteriously it started working again. Last night both low beams went out but the highs still worked. I changed bulbs today, both of the old low beams were shot. Now i have a very weak drivers side light, the passenger side looks ok while the truck is on (running lights) when i go to the switch i lose the drivers side ligth all together, high and low beam? I have tried swapping the relays around and it made no difference. Please help!!!
