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.
