ABSTRACT:
Flash lamp array sequencing circuits in which the lamps are provided with heat-sensitive switch material on the outside surface of the bulbs and extending between lead-in wires. The switch material initially has a relatively high impedance, and changes to a relatively low impedance between the lead-in wires when heated by the lamp when it is flashed. A coating of lacquer or plastic is provided over the bulb and switch material.
