Feradyne Outdoors Nockturnal Universal Lighted Nocks Orange - NT-315

Nockturnal lighted nocks feature a patented string-activated linear switch with piston-driven assembly that reliably activates the LED with each shot. These universal-fit nocks use super-bright LEDs and long-life lithium batteries for extended illumination on arrows and crossbow bolts. The orange polymer nocks are designed to fit nearly any arrow shaft size and come as a 3-pack.
