Boo, the switch I used came off an old laser sight that I had for my .22. I snipped it off,spliced in some speaker wire. I drilled a hole in the tail cap of the light(5/16)and a smaller hole just off to the side to run the wires through. The wires go to each end of the battery pack thing. The light is a 90 lumen Coleman from wallmart. It came w red and blue filters that screw on. Cost $20. Easy to do n works like a charm. Proof is I'm the main thread area."night hunt success"
Thanks for the invitation...
