Abstract

In the headlight of a motor vehicle, a holder of the objective is secured against rotation but is axially displaceable in the housing of the headlight. In order to adjust a width of cut of the objective a rotatable spacer ring, provided with projections cooperating with respective projections of the housing, is positioned between the holder and the end wall of the housing so as to adjust the position of the objective on an optical axis of the headlight.
