To facilitate aiming of a motor vehicle headlamp, e.g. as specified in U.S. Lighting Standard SAE J602, a motor vehicle headlamp having a housing with a light-transmitting front cover and a lamp reflector body mounted completely within the housing has an abutment carried by a rod at the top of the headlamp. The rod is slidable in bearings and connected with an adjusting screw for the lamp reflector body so that adjustment of the screw also moves the rod. A conventional mechanical headlamp aimer in mounted on the light-transmitting front cover of the housing in known manner and engages against the abutment.
