A method of illuminating a target area and driving rotation a driven tool comprises coupling a light attachment assembly to an elongated extension member by placing a portion of the elongated extension member within a hollow portion of a sheath of the light attachment assembly. Activating a light source of the light attachment assembly. Positioning the driven tool within the target area while grasping the light attachment assembly. Driving rotation of both the driven tool and the elongated extension member while grasping the light attachment assembly when the driven tool is positioned within the target are such that the portion of the elongated extension member housed within the hollow portion of the sheath rotates relative to the light assembly.

An illustrative embodiment of the present disclosure provides hand-held power tool which includes a housing, a motor, and an output spindle. The housing supports a motor having a rotor configured to rotate when the motor is supplied with power. The output spindle protrudes from an output end of the housing, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The housing also supports at least one electrical accessory that is connectable to an external power connector located on the housing.
