Abstract

A wheel marker including a solar cell and disposed on a wheel cap so as to allow the present rotating state of a wheel 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 solar cell electricity generating section circumferentially extending around the central part of the wheel cap, a brightness detecting sensor disposed at the center of the wheel cap on the front side, an inverter disposed on the rear side, and a battery disposed on the rear side of the wheel cap and adapted to be charged by the solar cell. 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 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 front surface of the wheel cap.
