Abstract
Abstract Activation means for activating at least one percussive flashlamp unit located within a flashlamp article. An activator moves within a casing when released by a pivotal retaining arm to engage and effect release of the flashlamp unit's striker spring. The retaining arm provides release of the activator in response to external actuation, e.g., the opening of a door or window.
