Dodge Demon Headlight switch removal

The switch body has a locating tang ( square block ) that keeps it from turning in the dash. There is a little wiggle room in the dash female square opening so sometimes... Just counterclockwise pressure against the bezel nut while reaching under and working the switch back and forth in that wiggle room will loosen the nut. Most will use needle nose, snap ring plier, something other the special bezel nut tool to geter done.
and yes you just might cure the dimmer rheostat with contact spray. Whole new switch is about 14 USD.
The dome lamp socket is hot at all times. The door jamb switches and headlight switch provide the ground. There were 2 different dome lamp fixtures. One has a typical push and turn bulb base while the other has a linear bulb between 2 contacts. I don't have either bulb number.
