Abstract: A pneumatic lighting apparatus for use with a pneumatically driven tool includes a pneumatic motor driven by compressed air, and an electrical generator that is driven by the mechanical output of the motor for generating an electrical current. A lamp is provided in a circuit with the generator for emitting light adapted to be directed onto an area in which the tool is being used. A conduit is provided which is connected between the outlet of the motor and an inlet of the tool in order to deliver compressed air from the apparatus to the tool. In order to permit control of the lighting apparatus independent of operation of the tool, a control valve is provided for controlling the flow of compressed air through the motor, and an exhaust valve controls the flow of compressed air between the conduit and an exhaust.
