Abstract
A signalling wheel cover, including inner and outer housings, is provided with lights around the circumference of the outer housing which sequentially illuminate as the two housings rotate with respect to one another. The outer housing is secured to a vehicle wheel. Coils, to which the lights are connected, are mounted to the outer housing. The inner housing, to which magnets are mounted, is rotatably secured relative to the outer housing to allow independent rotation of the two housings. As the wheel carrying the outer housing begins to rotate, the inner housing tends to resist the rotation due to its inertia. This resistance to rotation can be enhancedd by adding a counterweight to the inner housing so the inner housing is mounted pendulously. As the coils rotate through the magnetic fields of the magnets, current flow is induced in the coils which causes illumination of the lights in a sequential pattern.
