A light bulb is mountable from a rear side of a bowl shaped headlight reflector by extending the light bulb through an opening in an apex of the reflector and rotating it less than 180 degrees. Radially protruding tongues of a plate shaped socket of the light bulb slide under a ring formed element during the mounting. The ring formed element is constructed of spring wire having a polygonal shape. The number of angles of the polygonal-shaped wire is the same as the number of tongues of the socket. The polygonal-shaped wire engages the reflector at its corners, or angles, and the middle of each side thereof is biased to tightly engage a tongue of the socket.

Vehicle headlight

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.

Headlight for automobiles

An automotive headlight with a bowl-shaped plastic reflector. The reflector has at its apex an opening surrounded at the rear of the reflector by a sheet-metal retaining ring. The ring accommodates an incandescent lamp. The lamp is inserted into openings in the reflector with its securing tabs bent back toward the reflector and is secured to the reflector by barbs on the securing tabs that engage the edges of the holes. To improve the headlight to the extent that the openings in the reflector that accommodate the securing tabs are large enough not to shorten the life of the tool and do not need to be produced with such a precise tolerance, while still ensuring that the retaining ring will fit the reflector reliably and snugly, the securing tabs are bent into a U and the openings in the reflector that accommodate the tabs are quadrilateral and approximately as high and as wide as the tabs.

Automotive headlight

A vehicle headlamp in which an optical unit for a sealed beam is mounted between a carrier ring fixed to the vehicle and a removable cap ring. On the carrier ring two diametrically opposed pins are supported in bearing bushes to be coaxially rotatable and axially displaceable. Both pins are fixed to a resilient clip that bears on cam faces on the outer ends of the bushes. Upon pivoting the clip, the pins are jointly rotated and, by the action of the cam faces are axially oppositely displaced. As they are extended outwards they engage recesses in the cap ring to secure it to the carrier ring. Eccentric portions on the outer ends of the pins thereupon bear on the recesses with further rotation of the pins to draw the cap ring and carrier ring together to grip firmly an interposed rim of the optical unit.
