Patrick is probably your best bet for a trouble-shooting approach. I believe the lights work outside the ignition switch. I know I run with my parking lights on and I'm always forgetting to shut them off when I park the car and have to go back and shut them off. Not sure on headlights without checking though but I think they are the same. My gas gage doesn't change either when I turn the engine off - it stays where it was. But the red light remaining on is an issue.
