The listing, Build your own lighted nock for your arrow has ended.
I will send you directions on how to build your own lighted nock for your arrows for less than half of what you pay for one new. To buy one new is around 10.00 dollars. With my method you can build one for around 4.00 dollars, maybe 3.00 dollars. The nock will come on with the release of your arrow. You will find your arrow quickly with no effort so you can recover your animal as soon as you get out of your stand. They work very well in low light or if you sit in your stand until dark you dont have to look all over to find your arrow. They come in red,yellow or green.I found the red to work best though.
