I use a chepo floro bulb thing I picked up fron the hardware store. It lights up things good enough and has lived thru a couple a drops. I mainly use the stinger flash light. I got 2 of them...........don't wanna get into the reason why I have 2 $100.00 dollar flash lights. I just buy the cheap floro ones and keep an extra handy so if one bites the dust, i got another. I also have a LED "head light" that you out one your head. It worked great while I was in Iraq and I use it alot around the house and while working on cars and trucks.
