Abstract
A flashlight includes a flexible core comprising a pair of conductive wires which electrically connect a source of power to a power using implement. A flexible spine surrounds the pair of conductive wires and includes a plurality of interconnected universally rotatable members. A resilient sleeve engages the outer surface of the rotatable members forming the spine. The flashlight includes a working end housing and a base housing. A first anchor connects one end of the flexible core to the base end housing and a second anchor connects the other end of the flexible core to the working end housing. The outer surface of the resilient sleeve is restrained against relative twisting or longitudinal movement with respect to each housing.
