ABSTRACT:
A warning lamp, provides multi status indication by being illuminated in selected ones of a plurality of colors or by flashing a selected color or colors sequentially. The lamp has a pair of printed circuit boards disposed, one in a base and another upstanding from the base along a central axis, extending midway through the upstanding board. Around the upstanding board and coaxial therewith is a lens which is mounted in assembled relationship with the boards and the base. The upstanding board has arrays of light emitting diodes (LEDs), disposed along spaced lines which are parallel to the axis. The LEDs along different lines provide light of different color, for example, red, green and amber. The printed circuit boards provide a subassembly in which the bottom portion of the upstanding board and the other board are contained in a plastic casting disposed in a recess in the base. The boards carry circuits and circuit components which connect the arrays to leads which extend through the base and which carry current for each of the groups of lamps in the arrays so that they may be selectively illuminated or illuminated in sequence.
