A light generator includes a generator housing, an axle, a magnet, a coil device, a lamp unit, and a resistance unit. The generator housing is adapted to be secured to a rotatable object for co-rotation therewith, and is formed with an axle hole. The axle is mounted rotatably in the axle hole, and has a coupling end that extends out of the axle hole. The magnet is disposed in the generator housing, and is mounted co-rotatably on the axle. The coil device is mounted in the generator housing, and surrounds the magnet. The lamp unit is connected electrically to the coil device. The resistance unit is mounted on the coupling end of the axle to resist axial rotation of the axle. Rotation of the generator housing with the rotatable object induces electrical currents to enable the lamp unit to generate a light output.
