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 patent-pending string-activated "hidden linear switch" is protected deep within the nock and will not turn on or off inadvertently. Battery life is over 20 hours.
Nocks can go straight form the package to the shaft in fully operational condition. No prep work needed. Just insert it, and you are ready to shoot.
