A generator and lighting assembly is provided for use on a mechanism, e.g. a power driven tool, having a shaft that is rotated during use. The assembly includes a rotor assembly 122 including a rotor shaft 102 affixed to the mechanism shaft, and a permanent magnet 132 supported on the rotor shaft for rotation therewith. A stator assembly 124 is also provided, and includes a body presenting pair of electrically conductive arms 138 extending on opposite sides of the rotor and an electrically conductive shank 140 connecting the arms together, and a winding 136 of electrically conductive wire supported on the body and presenting a pair of opposed ends. The assembly includes a lamp assembly 128 for providing illumination to an area to be lighted, and includes a light emitting diode (LED) embedded in a solid transparent bulb formed of a synthetic resin composition. Electrical conductors connect the ends of the winding to the LED to form a circuit for supplying current to the LED upon rotation of the rotor magnet 132 within the stator assembly 124.
