PCT No. PCT/NZ97/00121 Sec. 371 Date Apr. 1, 1999 Sec. 102(e) Date Apr. 1, 1999 PCT Filed Sep. 29, 1997 PCT Pub. No. WO98/15426 PCT Pub. Date Apr. 16, 1998A method and apparatus for illuminating rotating wheels are described. The device requires no external power and relies on the rotation of the wheeled power generator located in the hub cap or other mounting area of the wheel. Construction comprises a coil having an axis of rotation, the coil being substantially on the axis of the wheel so that when the wheel rotates, the coil rotates similarly. A magnet is mounted around the coil in such a manner that it is self orienting. This is achieved by means of an asymmetric weight which is of sufficient dimensions and weight so as to counteract the rotational tendencies of the structure to which it is rotatably mounted. In a preferred embodiment, the weight is attached to the magnet by one or more elongated members incorporating compression means which absorb transitory vibrations experienced by the weight during the vehicle's movement. The present invention may find application in road vehicles, although application has also been found in railway wagons and the like.
