Nockturnal lighted nocks are a breakthrough design that combines ultra-light performance with a high visibility light source and "instant-on" simplicity that activates upon release. The patented string-activated "hidden linear switch" is protected deep within the nock and will not turn on or off inadvertenlty. Turn the LED off by locating the "reset hole" in the side of the nockturnal and slide the inerior switch away from the arrow. Battery life is over 20 hours.
