My work truck which is a F##d, has a feature I like, open the door the dome light stays on for a couple of minutes and then shuts off. I want to do the same thing for my Sub. I have not found any kit to do this. My first idea was using a capacitor, but I do not think it would have enough storage to keep the light on for the two or three minutes I want it to. A adjustable time delay timer would work, but I can not find one. Anybody have any ideas on how to accomplish this? I just want the dome light to stay on for a couple minutes with the door open and then shut off, even with the door open. I want the manual dome light switch to work as normal.
