ABSTRACT:
A hand held tool has a handle of generally rectangular cross section and a bulbous end portion. A shank is embedded in the handle and extends from the end opposite the bulbous portion to terminate in a work engaging tool such as a screwdriver blade. A self-focusing light bulb is carried in a relieved portion of one side of the handle and is electrically connected to a battery also carried in the relieved portion. A retaining member providing a metal strip removably mounts in place on the handle to retain the battery and light bulb in the relieved portion and to provide a smooth closure therefore. A tang on the metal strip engages one end of the battery, and the other end of the strip extends forwardly in slightly spaced relation to the base of the light bulb. An annular member encircles the end of the handle adjacent to the shank and has a plurality of spaced detents formed around its inner periphery, these detents being adapted to hold the annular member in place and to engage and depress the end of the metal strip into electrical contact with the base of the light bulb when the annular member is rotated. An inwardly extending flange is provided on the annular member to enclose the light bulb and is either transparent or is formed with a light transmitting opening which becomes aligned with the beam of light emanating from the light bulb when the annular member is rotated to its "power on" position in which the electrical circuit is completed.
