The invention relates to a signal lamp emitting coloured light, in which there is a series arrangement of the incandescent lamp, a colour filter shaped like a hood, a colourless optical pane, and a colourless, or colour-neutral, transparent colour pane. The colour filter and the optical pane are equipped with collecting optics that are tuned to one another. A high light efficiency is ensured as a result.
