Coast LED light from the wHore Depot. It works great, because it has brass conductors unlike most aluminum LEDs that work crappy once the aluminum corrodes. I put a key chain loop on it, and attach to my belt loop with a lanyard so it is not weighing on my pocket when I put it in there. Only thing is the buttons stick out too far, so it is easy to accidentally turn on and kill the batteries, I fixed this by grinding the buttons in a bench grinder. I also have my trusty Milwaukee 18v power plus for the bigger jobs.
