A flexible omnidirectionally reflective horse lead has a central portion, and mechanical attachment means to accommodate a bridal bit ring. The lead reflects an incoming light beam from a walker or horseback rider back in the direction from which it emanated, preventing dangerous encounters during dusk or nighttime hours. The omnidirectionally reflective elements may be incorporated in a horse harness, or in a halter suitable for horses roaming in a paddock or field. The reflective elements are created by surrounding a central braided rope of nylon or polyethylene fibers with a cylindrically braided reflective sleeve. The braided reflective sleeve is composed of narrow width reflective strips thermally bonded to a flexible polymeric sheet with attached corner cube or microsphere retroreflectors. Due to its braided construction, the reflective elements reflect light omnidirectionally over a large angle of acceptance, illuminating the horse harness or halter. An improved measure of safety is thereby provided for both the horse and the horseback rider.
