Patent ID: 8230823

Claim:
A method of illuminating the area in front of a collared dog in dark conditions, eliminating the need for a dog owner to carry and direct a light source, comprising: attaching to the neck of the collared dog a housing containing at least one light source, a battery power supply for said light source, and a switch connected between said light source and said power supply for energizing and de-energizing said light source, said housing being attached to the neck of said dog by an adjustable band below the collar on the dog so that said housing and light source are located in front of the chest of the dog below the collar on the dog so that said light source is located substantially below the snout of said dog to minimize blockage of light by the dog's snout, said light source being oriented to direct light onto the ground and forwardly well in front of the dog from below the dog's snout, said band being adjustable to fit around the necks of dogs of different sizes, said light source comprising three laterally spaced light emitting diodes, the two outboard diodes oriented to direct light forwardly past opposite sides of the dog's snout, and the central diode oriented to direct light forwardly and downwardly, wherein said light source, when energized, is of sufficient brightness to illuminate the area in front of said dog so that said dog owner can observe the illuminated area for control purposes.
