The invention relates to a flashing alarm light (1) for an alarm system (10), said flashing alarm light comprising: a flashing light source (2) for an optical warning in the event of a hazard; an energy store (3) for storing electrical energy (E); a switching element (4); and a control unit (5) for releasing the stored electrical energy via the switching element to the flashing light source. The flashing alarm light further comprises a housing (9) which has a fastening surface (BF) on the housing side for direct wall or ceiling mounting or for fastening to a base (SO) for indirect wall or ceiling mounting. According to the invention, the flashing light source is a thin film component consisting of organic semiconducting materials and producing planar illumination (OLED). In particular, the thin film component is attached to the housing. The thin film component has an inner surface (IF) facing the housing and a lighting surface (LF) that is directed away from the housing and outwardly arched. The lighting surface comprises e.g. a portion of the surface of a sphere, cylinder or ellipsoid. By means of appropriate shaping of the curvature, it is possible to adapt the radiation characteristics of the thin film component producing planar illumination to the European Standard EN 54-23 or the North American Standard UL 1971 v3.
