Abstract
The invention is concerned with a headlight for automobiles the interior cavity of which is ventilated with a tube filled with a desiccative. The tube is guided into an opening at the rear of the reflector and is fixed into place by means of a screw lock. A socket-like cover, exhibiting a ventilation hole, is locked into place and pushed onto the end section of the tube which protrudes out of the opening on the rear of the reflector. The socket like cover serves to protect the tube filled with the desiccative against contamination and flooding.
