Abstract: An LED of a lighted nock sequentially advances through multiple different emitted colors by exposing the nock to a magnetic field. The nock is placed in the activated or lit state. Then a magnet is brought within range of a magnetic sensor included in the electronic circuit of the nock assembly. The change in the magnetic field causes the electronic circuit to advance the emitted LED light to the next color in a sequence of multiple colors. Repeated removal and re-application of the magnetic field while the LED remains lit advances the LED color repeatedly through the available colors until the user reaches their desired color. Then the LED is deactivated or turned off. Then when the LED is re-lit, it will still be in the last color chosen, and will remain there until the color is advanced again.

Abstract: A nock body may include a first end and an opposing second end. A nock housing may include a proximal end that engages the first end of the nock body and a distal end opposite the proximal end.

An LED/battery assembly may be disposed at least partially inside of the nock housing. A fastener may be secured to the nock housing in a location that causes a width of the slot to narrow and secure the LED/battery assembly. A groove may be defined in the nock body beginning at the first end that extends towards the second end. A nock activation lockout can be provided to block an LED activation gap from closing so that the LED does not unintentionally turn on.
