There's another source for lights that can mount on your bow. Check Burnham Brothers
www.burnhambrothers.com they've got what's called a 'shooting light' for $34.95. They're powered by a pair of 9V batteries and will really light up a hog. They're designed primarily to mount on rifle scopes... but we noticed the clamp jaws match perfectly with a 'basic' stabilizer. We've since drilled a 5/16 hole in the base and found they can be mounted to the end of some stabilizers or can be used inplace of one.
Hope it helps.
