Abstract

A self contained, hand held light in the form of a baton having a handle of cylindrical contruction that forms a battery compartment therewith. A bottom cap is removably received for closing the lower end of the handle and for actuating a switch means that is connected to be actuated by the cap. A bulb is supported at the upper end of the handle, and circuitry for the bulb supplies current flow from a storage battery by a conductor strip that is bent at the opposed marginal ends into a switch and a bulb holder. A hollow light transmitting cylinder is attached to the upper end of the handle, and a solid nose piece is attached to the upper end of the cylinder. This provides a water-proof device that is useful of signaling, controlling crowds, and illuminating dark areas.
