Grilling lights

It just occurred to me that an LED grill light WITH a motion sensor would be handy. I don't mean a position sensor like the handle mounted Weber light, but a full blown, walk up to the grill and the lights come on arrangement.
Am I typically late with an idea and someone has already made it, or is this next "sliced bread, pocket on a shirt" invention ?
