Running lights stop working intermittently
My 2019 Lariat F250 running lights (taillights, mirror lights, license plate lights) will stop working. Brakes, and turn signal work. If I cycle the lights from auto to on they start working again. It’s happened twice last night with a trailer hooked up. Trailer lights were all functioning. I’ve read other posts where the running lights completely stop working but I didn’t see any where they come back on after cycling lights. Any idea what could be causing this? TIA

Being all the running lights, I would try a new headlamp switch.

In "auto" mode, with halogen headlights, the running lights will shut off in bright daylight leaving the headlights on as DRLs. Maybe there is something wrong with or interfering with the light sensor?
