Abstract
A flexible core for a hand-held device such as a flashlight includes 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. An adaptor including one conductor made from nickel chromium wire may be used to selectively connect the flashlight to a 12 volt source of electrical power in lieu of two standard C cells housed within the flashlight.
