Zusammenfassung:	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.
