Agreed. Accidentally bumping the switch upon exit/entry is by far the most likely cause here.Probably slightly bumping switch upon entering or exiting Jeep. I’ve done that a few times.
Noticing lately that the headlight dial is moving just slightly from Auto to On by itself.
Or more accurately from auto to almost On.
I have had to move to Auto again.
Initially I thought mine kept moving too, until one day I noticed I touched it with my knee!Yep my knee hits it all the time.
