Abstract
Lamp for optical light signals characterized by the fact that a light bulb mounted coaxially inside a reflector parabola closed by a protective glass has a concentric envelope with this focus which is axially displaceable and is in front correspondence with a cap for seat thereof mounted in the center of the protective glass so that the displacements of said envelope reach two limit positions that determine darkness or light depending on whether or not the envelope is seated in said cap, said displacements being produced at the will of the lamp operator by means of a drive device provided with elastic means which tend to stably maintain the envelope in one of said limit positions.
