Abstract
An illuminated bowsight is disclosed which includes a light-emitting diode centrally located in a sighting ring and a battery to illuminate the diode. A switching device is provided on the bowsight to selectively connect and disconnect the battery to the light-emitting diode. The switching mechanism is arranged so that no additional wiring is required other than the two leads which are normally provided on a commercially available light-emitting diode.
