Abstract: The tool is a narrow one, usually a screwdriver or the like, formed of one piece of clear synthetic polymer composition material such as polycarbonate. The tool has a flange which fits into the front cover or shroud of the flashlight and overlies its lens. The shank extends out of the flange and is sized to engage upon a device needing adjustment. The end of the shaft has engagement means thereon which may be a flat screwdriver tip, a special screwdriver tip, or a socket so that an adjustment screw may be readily engaged even in a dark location.

Abstract: The base of the illuminated screwdriver attaches to the light source, and the screwdriver shank is attached to the base. The tip of the screwdriver is a flat metallic blade inserted into the shank. The shank is made of light transmissive material so that light from the source is delivered at the blade. A shield is slidably mounted on the shank to slide from a position away from the tip to a position surrounding the tip. The shield is made of insulator material to prevent the blade from shorting between adjacent screws.
