Abstract
Abstract A motor vehicle headlight having a casing containing a pivotally mounted reflector which is pivoted in response to movement of a piston rod of a hydraulic piston and cylinder unit at an end of a hydraulic remote control system. The casing has an opening so positioned that when the unit is fitted therein the piston rod can easily engage a force transmission arrangement acting on a periphery of the reflector to pivot it when the rod is moved.
