A control system for modifying the angular position of the headlights of a vehicle, on both sides of a normal preset position, according to the trim of the latter. The system utilizes a fluid pressure differential control to sense vehicle load by sensing the depression of the body of the vehicle relative to the chassis. By communicating the fluid pressure to an actuator at the headlights of the vehicle, the angular relationship between the headlights and the vehicle body may be varied as a function of the vehicle trim. The actuator is provided with a movable assembly of annular nested abutments resiliently urged a fixed stop of the actuator casing, and with a piston connected to the headlights subjected on one hand to said pressure differential and on the other hand to the strength of a spring biasing said piston into engagement with said movable assembly of abutments.
