ABSTRACT:
A multiple flash lamp array having an electrically conductive reflector unit positioned between the flash lamps and a circuit board. A radiation-actuated last-flash indicator switch is positioned on the circuit board behind the last lamp to be flashed and is connected between an electrical ground circuit run and another circuit run. An opening is provided through the reflector at the last-to-flash lamp, in alignment with the last-flash indicator switch, and the rear edge of the opening is shaped to contact the electrical ground circuit run adjacent to the last-flash indicator switch for electrically grounding the reflector.
