A selective light assembly for a sighting device associated with an archer bow or the like has a plurality of light collectors, such as optical fibers, that serve as sight points. An artificial light source is adapted for projecting radiant energy in a direction toward the light collectors and a base member is operatively associated with the light source. The base member has at least one window adapted for alignment with at least one of the light collectors. At least one of the light source and base member is adjustable between first and second positions, such that the radiant energy projects through the base member and onto first and second light collectors for selectively illuminating a sight dot associated with one of the light collectors.
