Abstract
An elongated flash lamp assembly which is sequentially advanced through a camera to permit each of the lamps within the assembly to become aligned with the camera's fixed reflector. Several heat-responsive (e.g. fusible) covers are located on the assembly's housing to permit the above advancement only after each cover has become physically deformed by the heat from the respective flash lamp located adjacent thereto. A mechanism for advancing the assembly is also disclosed.
