A collar has an elongated strap attached to a buckle for releasably connecting the collar to a pet animal or human. A tubular plastic body with phosphorescent material located within the body is located around the strap. The phosphorescent material when subjected to natural or artificial light emits light in dark environments. A modification of the collar has a strip of light reflective material attached to a plastic body with phosphorescent material incorporated therein. The light reflective material has a prismatic shaped surface for reflecting light and radiating luminescent light emitted by the phosphorescent material. A buckle and loop are concurrently joined to the plastic body during the molding process of the plastic body.
