I have motion sensor lights in my garage (my office is off the garage and I don't like leaving garage lights on all the time). One of them stopped working. I pulled the middle (or 3 AAA's) battery out and it started working again. I finally looked closely at the battery I removed and it showed signs of having shorted out. I put in a new one and the light works again.

My question is if the light can work with two batteries, why are there spots for three? (The white button seems to be a battery door interlock, but the thing worked just fine with that button not pushed).
