A phosphorescent or light-reflective member is disposed on a holder supporting an elongated light-gathering optical fiber formed of a light-gathering plastic material. The sight is adaptable for use on rifles, handguns, bows, and other weapons requiring an aiming indicia. The light-gathering optical fiber provides a brilliant dot that is readily identifiable under bright light conditions, and the phosphorescent or light-reflecting member provides a supplemental light source which serves to provide an illuminated dot under low-light or dark conditions. The sight 10 effectively solves the problem of providing electrically-powered light sources for illumination of the aiming indicia under low light or dark conditions, or the requirement to precisely align the fiber or hollow tube with a light source disposed at the distal end of the fiber or tube spaced from the viewing end of the fiber or tube.
