Lights, car, action!

My car's dome light went out many months ago (six? eight?). I never bothered to replace it (or the one in The Beast's lair for that matter). I wouldn't usually mention such a blatantly lazy move (or non move in this case) except it's not just that I'm lazy- I abhor going to the car dealership.

Anyway, as I got into the car a few days ago, I noticed that the light now mysteriously turns on when the door opens. Weird.
