Other items, such as, glitters of various colors may also be added to make the wheel more attractive to children.

FIG. 2 shows an embodiment of the present invention that comprises a solid semiflat wheel 214 with lights 216. In one exemplary embodiment, the toy comprises one or more lights along the handle or in the inner portion of the wheel. The one or more lights may comprise light emitting diodes and wherein the one or more lights may comprise multicolored blinking lights. For example, the wheel may comprise any number of different battery-powered LED lamps with different colors that blink while the wheel rotates. Thus, in one embodiment of the present invention, the individual lamps are installed adjacent each other to form a continuous ring of light that may be of the same color, but most preferably of different colors. In another embodiment of the invention, the inner portion of the wheel comprises a single continuous strip of LED light array. Commercially available batteries, such as lithium batteries, are preferably used to power the lights. In a most preferred embodiment of the invention, the handle comprises a switch that allows the toy user to turn on or off all, or at least some, of the lights.

In another preferred embodiment, the lights are motion-activated so that the wheel's rotation activates the blinking of the lights. In another embodiment, the individual lamps may have their own separate switch for turning on and off. The lights may be attached to the wheel toy using various methods including using a double-sided tape, adhesives, screws, etc. In still another embodiment, the wheel may also include other implements such as bells and other music- or sound-playing implements that are activated via either a switch or some other mechanisms such as a motion sensing switch.
