ABSTRACT:
An elongated tubular body constructed of conductive material is provided and includes open front and rear ends. A combined reflector and lens assembly is supported from the front end of the body and a bulb is removably supported from the reflector and lens assembly and includes center and base terminals with the base terminal electrically connected, by the reflector and the lens assembly, to the body and the center terminal supported out of electrical connection with the body. Battery structure is slidably disposed within the body and includes a forwardly facing forward terminal in electrical contact with the center terminal of the bulb and a rearwardly facing rear terminal. A thick walled sleeve is disposed and longitudinally slidable in the rear end of the body and is constructed of deformable, resilient dielectric material. The front end of the sleeve includes a contact electrically contacting the rear terminal of the battery structure and a thrust member is mounted in the rear end of the body behind the sleeve for adjustable positioning therealong to variably bias the sleeve and thus the battery, forwardly in the body. The thrust member is constructed of conductive material and is in electrical contact with the body. A switch structure is supported from the thrust member and includes a switch actuator therefore disposed in recessed position within the rear end of the body and operable from the exterior thereof. The switch defines a ground terminal which is grounded to the thrust member and a second terminal which is insulated relative to the thrust member and disposed within the interior of the sleeve. A conductor wire is connected between the second terminal of the switch and the contact carried by the front end of the sleeve.
