I have 2015 f150 with factory led headlight. Headlights will only work when ignition is off or in accessory. Soon as you start it they won’t work

 

Have you made any changes to the truck recently? Added any new lighting or tapped into existing lighting circuits?

 

Remove the tune to see if that makes a difference.

Do you leave lights in "auto" mode? If yes, turn them on manually. Any changes?

 

I had raptor lights tapped into drl on driver side headlight thought that might be the issue. So I removed that splice and just hooked it back up without those hooked in.

 

I have had them in auto, turned them in manually, and even tried just the parking lights still nothing.

 

Sounds like something got confused. Try a KAM reset, no guarantee, but it's free.

 

KAM reset didn’t work

 

Sounds like there is either a backfeed somewhere during a "vehicle run condition" causing the lights to fail. There are multiple systems that only turn on when the vehicle is in run and/or running. I'd try disconnecting the battery and depleting the power from the system. You likely have a hardware issue, or an electrical issue somewhere within the circuitry or the modules.
