Abstract

A signal device comprising a casing, a plurality of lamp holders for lamp means disposed within said casing, a light transmitting cover for said lamp means, a control circuit connected to said lamp holders, said control circuit being switchable to illuminate a plurality of lamps in said holders simultaneously in at least two predetermined modes. The circuit includes means for supplying an electrical current to each lamp at least during periods when said each lamp is not illuminated said electric current being sufficient to maintain the filament of each said lamp at black heat.
