摘要： A signal device comprising a partially transparent package containing a plurality of percussively-ignitable flashlamps arranged in an array with respectively associated preenergized striker springs, and a movable member for sequentially releasing the striker springs to fire respective flashlamps in response to successive indexing. The device is adapted to be hand held and the movable member is adapted to be actuated and indexed directly by hand.
