Headlights only work with ignition off

So thanks in advance, cant find a solution to this, headlights not working while truck is running, no high or lows or flash, but if I shut the truck off headlights work fine highs and lows, all fuses checked and fine. Also all other lights and electrical working fine. Please help 2000 f350 7.3l cm sk2 flatbed srw 4x4 6.5" procomp lift hdx front bumper

I would pull out the Multimeter and see what is going on with your voltage when you're actually turning the key. Check fuses/relays for a bad i.e. Melted, slight crack etc.

There is a switch that switches your headlights from normal headlights to the plow lights. When the switch is flipped the regular headlights won't come on and the plow lights light. I'm going to guess that you bumped that switched and that its power is keyed so it only functions when the key is in the on position. Find that switch and change its position and see if it doesn't solve the problem.
