ABSTRACT:
A sighting device for use with an archery bow for hunting or target purposes, utilizing light emitting diodes which are battery operated and the intensity of which may be varied manually. The light emitting diodes are mounted at the ends of sighting pins which may be adjusted both vertically and horizontally, to compensate for distance and windage. The light emitting diodes are shaped so as to protrude beyond the end of the sighting pins and thus under bright ambient light conditions function to gather and disperse said ambient light even though not electrically energized.
