Firenock FLNS Lighted Nock System (3-pack)

The original patented Firenock lighted nock system. Each nock holds a lithium-cell circuit that lights up the moment the string releases — letting you visually track your shot, find your arrow in low light, and confirm impact placement on game.

Why FLNS

• Patented release-activated electronics — won't false-fire from vibration or bow draw
• Lasts 70+ hours of continuous illumination (BL battery) or 36 months shelf life
• Replaceable batteries and circuits — never throw away the housing

Choose your style

Match the style code to your arrow's nock fit (A, C, D, D2, D3, E, F, G all available). If you're not sure which style fits your arrow, consult our arrow builder or message us with your shaft brand + model.
