The light has an opaque screen (13) in the path of the rays of light between the bulb (6) and the reflector (1). The screen has a cutout (15). The reflector (1) consists of at least two paraboloid reflecting surfaces (8 and 9) with optical axes (10 and 11) that meet at an angle .alpha.. The mask (13) is adjusted so that the cutout (15) directs the light against one or the other of the reflecting surfaces (8 or 9).
