I use, and recommend, the Eagles Flight Archery light holder that Terry Green mentioned. The light that I use in it is a Ulako zoomable green LED flashlight. That flashlight is about $10 or $12 US dollars on the big auction site. That set up takes care of my bow light needs.
I also use, and recommend, a feeder light. I can attach it to a feeder or tie it in a tree or to a post to light the general area after dark with green light. Some of these lights turn on using a movement sensor, and some use a light sensing photo cell. I prefer the photo cell type.
I also use lighted nocks. After a lot of testing I have settled on Glory Nocks as the best.
