Abstract: In a motor vehicle lamp of the type comprising a body (2), a bulb (3) within the body (2), a transparent glass (4) having a prismatic internal surface (5) for receiving light rays emitted by the bulb (3) and focusing them outwardly in a beam having predetermined characteristics, and a colored filter (11) interposed between the bulb (3) and the transparent glass (4), the prismatic internal surface (5) of the transparent glass (4) includes diffusing lenses adapted to scatter light rays passing through the transparent glass (4) from the exterior in all directions within the body (2) of the lamp. The lamp further includes an internal reflective wall (17) for reflecting the light rays scattered within the lamp body (2) over the entire surface of the transparent glass (4), so as to prevent the colored filter (11) from being visible from the exterior when the bulb (3) is off and the lamp is illuminated from the exterior.

Abstract: The reflector has a transparent body in the form of a paraboloid with a light source located within the reflector along the axis of symmetry. The inner surface of the reflector has a plurality of circular ridges of generally triangular cross-section, each ridge being defined by a cylindrical surface portion the axis of which is coincident with the axis of symmetry and by a frusto-conical surface portion adjacent to said cylindrical portion which lies on a cone having its axis coincident with said axis of symmetry with each of the cones having a common apex located approximately at the center of said light source.
