Abstract
A light symbol projection device is disclosed. The light symbol projection device has a housing which is temporarily secured within a receiving mechanism. The receiving mechanism is embedded within a product such as, for example, a shoe. The light symbol housing may project, in various colors, a word, pattern, symbol, logo or other indicia on the ground. The light symbol housing may be interchangeable so that the receiving mechanism may receive various light symbol housings having different light projections. In one embodiment, a speaker associated with the device may also provide an audible sound.
