The nock body 10 preferably includes a string portion 18 and a shank portion 20, which extends from one end of the string portion 18. A string slot 22 is formed in an opposing end of the string portion 18. A first pair of opposing notches 24 are formed in opposing sides of the string slot 22 in substantially a middle of a length of the string slot 22. A second pair of opposing notches 26 are formed near an end of the string slot 22. A battery bore 28 is formed through the shank portion 20 and into the one end of the string portion 18. An LED body cavity 30 extends into the string portion 18 from a bottom of the battery bore 28. A light hole 32 is formed through an end of the string slot 22 and into the LED body cavity 30. A switch opening 34 is formed through a wall of the nock body 10 and into the battery bore 28.

With reference to FIGS. 3-5, the light unit 12 preferably includes a modified top hat LED 36, an LED housing 38, an LED housing insert 40 and a switch 42. The modified top hat LED 36 includes an elongated light emitting portion 44, a base portion 46, a straight electrical lead 48 and a bent electrical lead 50. The elongated light emitting portion 44 extends from one end of the base portion 46 and the pair of electrical leads 48, 50 extend from an opposing end of the base portion 46. The elongated light emitting portion 44 includes a cylindrical shape. The elongated light emitting portion 44 acts as a light source and a plunger for axially moving the light unit 12 within the battery bore 28. The LED housing 38 includes a round outer perimeter and an insert notch 52 formed in substantially a middle of a length of the LED housing 38 to receive the LED housing insert 40. As a result of the insert notch 52, a first end plate 54 and a second end plate 56 are formed. A pair of lead holes 58 are formed through the first end plate 54. A lead hole 60 and a bent lead opening 62 are formed through the second end plate 56. A terminal bore 64 is formed in the second end plate 56 to receive a positive terminal 17 of the pin battery 16. A switch groove 65 is formed in a top of the LED housing 38. A switch clearance slot 67 is formed through the LED housing 38, adjacent the first end plate 54.
