ABSTRACT:
A wheel marker disposed on a wheel cap so as to allow the present rotating state of wheels of a vehicle to be visually recognized from a remote location includes as essential components a light emitting section radially extending toward the center of the wheel cap, a brightness detecting sensor disposed at the central part of the wheel cap on and along the outer surface thereof, an inverter disposed on the inner surface of the wheel cap, and a battery disposed on the inner surface of the wheel cap to serve as a power source. The light emitting section includes a light emitting element which usually comprises an electroluminescence element or a light emitting diode. In response to an output from the brightness detecting photosensor, the inverter is activated to turn on or turn off the battery. To turn off the battery when there is no need of activating the light emitting section, e.g., in the daytime, a power switch is disposed in position on the outer surface of the wheel cap.
