NAP Thunderglo Illuminated Arrow Nock Blue 6-Pack

The NAP Thunderglo is an illuminated arrow nock engineered for bowhunters who need to track arrow flight and recover game in low light. Built around a polycarbonate blend nock with an aluminum shaft, it delivers a bright LED flash that lights the moment the arrow is released and stays lit until the shooter manually disengages it.

The Thunderglo's auto-on system activates at release with no switches to manage in the dark, so every shot registers a clear, visible trail. The ultra-bright LED remains illuminated until the nock is unclicked to power it down, helping the hunter read penetration depth and follow-up shot placement on the spot.

Fitted with universal collars, the Thunderglo fits G, X, H, and S class arrow shafts, dropping into most standard hunting setups without modification. This listing is a 6-pack of blue Thunderglo lighted nocks, ready to install in your favorite hunting arrow build.
