'''Sounds like you have either a bad ground, a break in the wire or possibly a bad headlite switch'''
good guess
preston,
'''What does a bad ground mean, the ground wire isnt touching metal or something?'''
electrical circuits work because they need a power sourse and a return to ground. by havong a complete circuit +/- the lamp lights. if you have a bad ground several things can happen. like nothing works or dim lamps both LED's and incandesant bulbs, or the list goes on. bad grounds (gnd) effect anything that requires juice to operate. the best thing anybolter can do is check your truck and make absolutely sure ALL gnds are solid
battery to main frame
engine to main frame
cab to main frame
gas tank to main frame
bed to main frame
bed and or roll pan to main frame
radiator to main frame.
THIS means a good bare metal scraping and a good solid wire to each part. i coat all bolts after i have done this w/ an anti-corrosive paste, NCP-? , so no air gets to and or water which starts corrosion/rusting. available at any flaps or battery supply.
double check the rt ground wire....
BTW LED's work on very little voltage.
a good tool to have when shooting electrical trouble is a test light. they are easy to make or just go buy one. a VOM is another great tool. about $30-40 total. if you buy good tools they last a lift time...... unless some sorry Ba-_t@$d steals them.
when someone tells you to check this or that a test light can easily do this.
