Abstract: A self-containing accessory providing illuminated decoration of a cake or like, comprising, in certain preferred versions, an externally applied decorative cover of eye-defining light-transmissive portions and including a module, secured to the underside of said cover, to provide flashing illumination by means of an electric light source, battery, and interconnecting circuitry contained therein; the module being positioned such as to locate the electric light source beneath or within said light-transmissive portions so as to give the visual appearance of winking eyes; a recess being within the cake to receive the module. Another embodiment carries circuitry beneath the cake with illumination being provided atop a probe-like extension inserted upward from beneath said cake. Another embodiment achieves illuminiation by use of phosphorescent devices. Yet another embodiment achieves illumination by filtering light through various light-transmissive materials.
