Dimmer switch or door jam switch ?
 

Went out for a bite to eat the other night, while dark, noticed my dome light on in my truck. Thought well the dimmer switch dial must have been turned on. No not wasn't it, still on...Tried both door jam switches, but usually if one of those go bad, you have no dome light at all. Had to remove dome light bulb, and bulbs under dash both sides. Has anyone experience this where the lights stay on ?
