Barnett Headhunter strobe-lighted nocks enhance shot visibility in low-lighting settings. Strobing light assists in finding arrow and provides visibility to where shot placement occurred. The multicolored strobing lights alternate between multiple color patterns, 'pulse', 'fade', and 'flash' which enhance the visibility of the arrow once it has been shot. Strobe-lighted nocks are easily controlled with an on/off switch. The lighted nocks are designed to fit .300” inner diameter crossbow arrows.
