A wheel made of an optically conductive material is provided at a hub thereof with a power supply device. A plurality of light emitting elements are connected to the power supply device and separately disposed in spokes of the wheel. Alternatively, a plurality of optically conductive elements, which may have a specially designed configuration, shape or color, are separately fixedly mounted on the spokes of the wheel with the light emitting elements mounted therein. Light beams emitted from the light emitting elements are transmitted outward via the spokes or the optically conductive elements to provide a visually good warning effect. Such wheel is particularly suitable for use with bicycles, tricycles, and strollers.
