A lighted nock assembly may include an LED/battery assembly, a nock housing and a nock body. The LED/battery assembly can include an LED and a battery. The nock housing can include a cylindrical structure so that an outer surface is inserted into a rear end of an arrow, wherein a portion of the LED/battery assembly is disposed within the nock housing. The nock body can be linearly movable towards and away from the nock housing. A portion of the LED/battery assembly is secured within the nock body such that moving the nock body away from the nock housing along a straight line turns the LED from a lighted state to an unlighted state.
