A light-emitting golf ball using a small generator includes a core that is a center point of the golf ball; an inner shell formed to surround the core; an outer shell formed to surround an outer surface of the inner shell and struck by a golf club; a generator positioned on one side of the inner shell and generating a current based on a rotational force caused by a stroke; and a light emitting portion located on one side of the inner shell and providing light so that the golf ball emits light based on the generated current. According to the present disclosure, the golf ball emits light, and thus it is easy to track a trajectory of the golf ball. In addition, it is possible to more easily determine the trajectory and position of the golf ball when the day is cloudy or enters the night.

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.
