It took me a few months before I thought of this, figured I'd share in case anyone is in the same boat as I am. I put these small, motion detector lights in my prop. fridge. Long lasting battery, light doesn't stay on long to drain them, and plenty of light to see what you're doing in the corner of the fridge.

4 D cell light built into the Servel 400 lasts a year+ for us. Those could be handy lkights for many things though.
