Abstract: An illuminated pet collar including a light source and a power source disposed along a strap member. A switch is included for providing an electrical connection between the ends of the strap member so that power is provided to the light source only when the ends of the strap member are connected to each other by the closure means. In one embodiment, adhesive closure members disposed at either end of the strap member. Connection of the two adhesive members to each other completes the electrical circuit within the strap member by placing a pair of ferromagnetic reeds in magnetic communication with a magnet to close the electrical circuit and provide power to the light source. In a second embodiment, a conventional buckle, with a stem member, is disposed at one end of the strap member with punch holes having metallic eyelets disposed at the other end of the strap member.
