My wife has an 04.5 f150 its got the digital brand hid in the fog lamps and led in the head lamps. The problem is when the low beams are on with the fog lights the high beam side is on to and the high beam indicater light on the dash is just barely on. I did some reading and everyone is saying to do the bambi mod to the fog light relay,so I did the mod tonight and when I turn the high beams on the fog lights stay on but no high beam lights. When I go back to the low beam side the lights work normal on the low side now.

 

You have all aftermarket stuff in there, hard to troubleshoot.


I would guess it has to do with those LED headlights you have. Switch back to the halogen and see if the problem goes away.
