Abstract
Abstract The present invention is an illuminatable pet leash device. It includes an elongated tube which is non-opaque and which is of sufficient length, strength and flexibility to be used as a pet leash, and a handle and a pet collar attachment mechanism, one each being connected to opposite ends of the tube. In addition, a set of battery operated illumination circuitry of the flashlight type is included, which is located within the handle. There is an on-off switch connected to the set of circuitry, and a light bulb connected to the set of circuitry and connectively positioned with respect to the handle so as to be capable of shining away from the handle and into the tube. Lastly, the device includes at least one bundle of optical fibers contained within the tube, positioned in the light path of the bulb so as to be capable of fiber optic illumination within the tube.
