OK - in my head I was just making it more complicated than it was.

Dome light is still OK since he said it was the passenger & not him that couldn't find the handle.

Your application might be better for the blind date scenario since he wouldn't be getting out to open her door. But on the other hand, he prolly wouldn't be shutting off the engine either.

Actually, I've met Eric's GF & she's a keeper so he knows I'm just kidding.

I guess he could trigger the 555 from pwr ant lead from his head unit & get the same effect.
