Abstract: In a headlight including a housing supporting a reflector with a bulb and having an opening for handling the bulb, a hood of elastic material is provided, which closes the opening from the rear side of the housing. An annular sealing lip is provided on the hood itself which in assembly lies against the outer surface of the conical ring portion formed on the rear wall of the housing. An open hinge with bellows and a tongue, engageable with a shoulder on the rear wall of the housing, is provided at one side of the hood and a snap arrangement is provided on a diametrically opposite side of the hood to secure the hood to the housing.

Abstract: What follows is the description of an improved hydraulic apparatus for the automatic adjustment of the inclination of the headlights of a motor vehicle, the adjustment being a dependent function of the axle load. The apparatus has a level sensor at each axle and each level sensor contains one metering piston and two positioning pistons. The rear axle level sensor is connected via two separate hydraulic lines to the front axle sensor, and the front axle sensor is in turn connected via two separate hydraulic lines to the positioning elements of the headlight housings. The internal construction of the two level sensors is substantially identical and is chosen such that the system is also suitable for manual adjustment.
