Craftsman makes a similar LED light. It has a small wheat bulb on a thin flex shaft. Works on 2 AA batteries. I use it for sticking into plug holes and checking out pistons and cylinder walls. Also use it for checking gun barrels and receivers. Great for getting into hard to see areas. Cost was only about $10 if I remember right.
I cant find it on the internet, but I know they have 'em, cause Ive got one. A very handy little light.
Ive never built a cammer either.
