摘要： The invention relates to an indicator lamp, in particular for an electromechanical command device. The indicator lamp comprises a housing (1) and a light source (2), which is arranged in said housing (1) and emits light when supplied with energy. Furthermore, a lens arrangement (5) is provided, comprising a first lens unit (6), which is arranged in the propagation direction of the light emitted by the light source (2) and is built such that light beams emitted by the light source (2) exit substantially parallel from a side of the first lens unit (6) that faces away from the light source (2). According to the invention, the lens arrangement (5) comprises a second lens (7), which is arranged on the side of the first lens unit (6) that faces away from the light source (2) and is built such that some of the light beams exiting from the first lens unit (6) are directed with respect to the propagation direction towards a transparent side surface of the housing (1).
