I have them in my axis arrows, just replace the nock with the g force nock and shoot it, the g force developed during the shot turns the light on, tap the nock on a hard surface and the light goes out. The manufacturer has a video on there site I believe but also found it on u-tube searching for lighted nocks. The have worked very well, most reliable I have found and have been shooting one in a practice arrow for several weeks now and still going strong.
