Abstract: A headlight for a vehicle has a reflector, a holder on which the reflector is adjustably supported, an adjusting device for adjustment of the reflector, the adjusting device including an adjusting screw which is rotatable about its longitudinal axis and which is non-displaceable in direction of the longitudinal axis, an indicating device which indicates a deviation of an adjustment of the reflector from a prescribed position, the indicating device having an indicating element which is screwable in a threaded shaft of the adjusting screw, the indicating element being non-rotatable but displaceable in direction of the longitudinal axis of the adjusting screw, the indicating element having a springy, expandable threaded shell which is open over a part of its periphery and provided with an inner thread, the indicating element being pre-mounted on a part of the holder in a position which is separate from the adjusting screw and so that a threaded connection of the indicating element with the adjusting screw is per

Abstract: In a bulb assembly of a vehicle headlight the bulb has a socket formed with an outer annular groove which conically converges towards a filament positioned in a lower portion of the bulb. An O-ring inserted into the groove seals the bulb against a headlight reflector in assembly. The width of the groove in the axial direction of the bulb is selected so that upon pulling the bulb out from the reflector the O-ring performs a rolling motion so that a required pulling force is substantially reduced and a danger for a user injury is prevented.

Abstract: In a vehicle headlight a lamp holder for holding a bulb in an apex opening of a reflector is formed with three axially extended locking arms having hooks insertable into the slots provided in the reflector. Each slot defines on the surface of the reflector a bearing surface having an insertion portion and an arresting portion. Each hook, upon pivoting of the lamp holder is inserted into the assigned slot and is engaged behind the arresting portion to arrest the lamp holder on the backside of the reflector.
