I picked up a nice little lite at the local Wall-Mart store. I alread had a Nite Percer, but junked the head band and mounted the lite under the barrel of my rifle. About $15 aand uses D cell batterys. A cheap way to find out if you reall want to spend more money on the sport. I adpted my lite to a 6V battery which I run my head lite and spot lite off of.
