Patent attributes
A battery-operated electric power tool (1) includes a light unit (11) disposed on the front end of the main housing (2) and extending along the underside of the gear housing (6). The light unit (11) includes a light source (12) in a casing with the light emitting end of the light source (12) exposed through a hole at the front of the unit (11). The electric power tool (1) further includes at the front portion of the gear housing (6) a bumper (13) made of a molded rubber containing selfiuminous pigment. While the electric power tool (1) is operated with the light source (12) on, the bumper (13) absorbs and stores part of the light from the light source (12) and emits light therefrom, enabling the user to locate the bumper (13) in darkness or a dimly lit work environment even after sustained use in darkness.
