An illuminating device of the electric gaseous discharge type is provided. The device is adapted to display various selected configurations such as numbers, letters and the like. Gas filled tubes are formed into configurations which are segmented, a pair of electrodes being provided for each segment to control illumination of the segment. A shunt circuit is provided across each pair of electrodes to prevent illumination of the associated segment when desired. The various devices are preferably connected together in series circuit for energization by a single transformer.
