Abstract
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.
