Abstract: An ornamental antenna light is provided to be placed on an automobile antenna to decorate one's automobile or to identify the automobile to its owner. The light includes a particular configuration of molded plastic, a lighting mechanism, and a retaining means for retaining the light assembly onto the automobile's antenna. The configuration of molded plastic can be in different sizes, shapes, and colors to correspond to different designs, characters, and insignias. The molded plastic is preferably of the transparent or translucent type, so that when the internal lighting mechanism is activated, light shall be capable of passing through the plastic. The lighting mechanism is simple electrical circuit comprising a battery, an on/off switch, and a light bulb, all wholly contained within the configuration of molded plastic thus eliminating a need for an external light and power source. The retaining means comprises a locking switch and spring to positively engage the automobile's antenna.
