ABSTRACT:
A multiple lamp photoflash array of the FlipFlash type having flash-sequencing circuitry for causing the lamps to flash one at a time in response to firing pulses applied to the array. A radiation switch associated with the last lamp to be flashed causes a short circuit across the array's electrical terminals when the last lamp is flashed and actuates a last-flash indicator in the camera.
