I have the same problem that most everybody on here has. My driver side head light only works when it wants to. The high beam indicator comes on dim when i turn on the driving lights. And the driving lights were working backwards of the stock operation.
I ordered a relay harness and installed it... it made the driving lights work fine... but i lost my hi beams and the driver side light still doesnt come on. Well?? kind of??? it does when it wants to. If i turn the switch on and off two dozen times,,, it will turn on 5 times out two dozen. So it only works when it wants to. I checked and changed all grounds and rechecked all connections. In the big realm of things... The relay harness made my problem worse. But im not sure that the harness is for a hi low kit. It says it is.. But i dunno? Never seen the other harness. Any ideas? Im at a loss. Im gonna take everything off the truck and start over from scratch. Just to see if i missed something.

I Just don't know what's the problem. I would scrap the whole project if I wasnt color blind and had trouble seeing at night. I know about the bambi mod,,, but it seems that the my driving lights are working now... So I don't think I need to go bending the relays around. Unless someone knows if that will fix the problem. This shouldn't be this hard. Anyone got any ideas???
