Abstract: A lighting apparatus for vehicles having two primary headlights for visible low beam and high beam illumination, and auxiliary headlights that are mounted on the vehicle separate from the primary headlights. The auxiliary headlights generate infrared light and position light. An electrical control unit automatically turns the position light of the primary headlights off or on when the auxiliary headlight is turned on or off.

Abstract: A headlight, having a bowel shaped reflector with two focal points and a lens, includes a screen shaft positioned between the lens and the reflector, a rotational axis of which extends horizontally and at a right angle to an optical axis. The screen shaft is adjustable to a plurality of rotational positions and has in each rotational position a focal line, which produces a light-dark border of a light pattern. A mantle surface of the screen shaft has at least one surface portion which connects two focal lines which extends irregularly to, and deviates from, a cylindrical surface.

Abstract: A method for adjusting a vehicle headlight during cornering, involves creating cornering light by superimposing a light distribution pattern (37) with a greater horizontal dispersion than that of a low-beam light onto the low-beam light distribution pattern (36). A fog-light distribution pattern (37) of a fog light is used as the light distribution pattern having the greater horizontal dispersion. A single headlight unit can be used for generating such cornering light according to the method of this invention.

Abstract: Basic vertical and horizontal adjustment of a light beam (9) of a headlight are carried out with respect to a longitudinal axis (5) of the headlight by vertical (6) and horizontal (7) displacement of a lens (4) relative to a light source (2) and a reflector (1).

Abstract: To provide for improved light distribution of a vehicular headlight furning both depressed-beam and high-beam illumination, a shadow cap (9, 25) partly surrounds a main light source, typically filaments of halogen incandescent lamp, located in a reflector (2) which has two segments (14, 15) of different contours. The first one (14) of the reflector segments is optically associated with the main filament furnishing depressed-beam illumination, and this segment has a free-formed surface reflection contour. A second segment of the reflector is optically associated with an auxiliary filament (8, 18). The shadow cap (9, 25) provides a shadow angle of between 100.degree. and 140.degree. with respect to light emitted from the main filament (7) to define a shadow zone (12) and a light zone (13) on the reflector. The shadow cap is shaped and positioned with respect to the auxiliary filament (8, 18) such that the auxiliary filament is located within the shadow zone (12).

Abstract: A bowl-shaped reflector for a vehicle headlight produced by a casting process has a flattened section which extends to its outer edge. Grovoes are formed on an interior side of the flattened section which are elongated substantially in the direction of an optical axis of the headlight. The breadth and depth dimensions of the grooves are related to one another, and side surfaces defining the grooves have surface shapes such that, light rays falling directly in the grooves from a dim-light filament of a bulb mounted in the reflector are reflected a plurality of times on wall surfaces defining the grooves.

Abstract: A reflector for a dimmed or dimmable motor vehicle headlight is divided into an asymmetrical wedge-shaped sector, an upper sector, and a lower sector which are stepped axially from on another. The reflection surface is thereby formed such that a desirable light distribution is achieved without a correcting lens in horizontal and vertical areas perpendicular to a middle axis of the headlight. The desired light distribution of the asymmetrical wedge-shape sector is such that a corresponding point of every reflected light-filament image of each arbitrary point of the asymmetrical wedge-shaped reflection surface is positioned immediately near a prescribed borderline, such as a legislatively mandated borderline.
