A special effect light bulb combines both cathode glow illumination with fluorescent illumination. A pair of plates respectively electrically connected to a pair of electrical lead wires jointly define a word, phrase or wellknown symbol which is illuminated within an inert gas during operation of the light bulb. A third plate, having a fluorescent coating which is activated only by the ionized inert gas, is shaped in the form of a distinct symbol. 10091
