Abstract: A pneumatically driven tool (e.g., an impact tool) includes a pneumatically driven motor; an electric generator generating electrical power from movement of the pneumatically driven motor, or an impact mechanism connected thereto; and an on-board light that is powered by the generated electrical power. The pneumatically driven motor is rotated by compressed air or gas and drives an impact mechanism with one or more hammers and an anvil. Impact of the hammer(s) with the anvil, in turn, move an output shaft of the pneumatically driven tool. The electric generator harnesses the rotational movement of the pneumatically driven motor and/or the impact mechanism to electrically power the on-board light.
