I have an 05 with stock headlights and bulbs. Since.i have owned the truck the driver side light has been really dim. I pulled the light out last night and the 3 wires have been spliced. Would this cause me to lose voltage. Or could it be losing voltage somewhere else???

 

you could try and resplice them maybe your not gettin a good connection but not likey. my advice. buy hids and get rid of stockers anyways. my .02
