NAP Thunderglo Illuminated Crossbow Nock Red Half Moon 3-Pack

The NAP Thunderglo Illuminated Nock is a lightweight, LED-lit crossbow nock designed to light up the instant it leaves the rail. Sold as a 3-pack in Red with a half moon profile, each nock pairs a tough polycarbonate blend body with a rigid aluminum shaft for a secure, durable fit on standard crossbow bolts.

A bright LED activates automatically on bolt release, letting you track your bolt's flight and recover your shot in low light or after dark. The illumination runs for 30+ hours on the installed battery and is shut off manually once you've recovered your bolt. The universal fit is compatible with most standard crossbow bolt diameters, and the half-moon design provides reliable string engagement and consistent alignment shot after shot.

Whether you're dialing in a hunt at last light, knocking out an evening practice session, or just want an easier time finding your bolt in the brush, the NAP Thunderglo adds visibility to your crossbow setup without adding bulk or complexity.
