ABSTRACT:
A bar display comprising incandescent segmented display module presenting a plurality of dot positions to the viewer wherein a plurality of miniature incandescent lamps illuminate all the segments except one, the latter segment being illuminated by an elongated incandescent lamp capable of illuminating not only this one remaining segment but all segments or supplementing the miniature lamps depending on ambient light conditions. This arrangement permits a fully lighted dot position bar display with only one lamp thus saving power or permits a dot position bar display with each individual miniature lamp illuminated separately or a bar display responding to ambient lamp conditions, by utilizing only the elongated lamp alone or the elongated lamp plus the miniature lamps as desired.
