Title: Pneumatic control installation for headlights

Abstract: A pneumatically operated control system for the automatic alignment of motor vehicle headlights in which a measuring transmitter at each axle of the motor vehicle determines the change in distance of the axle to the vehicle body and, cooperating with a pressure modulator, causes the alignment of the headlights to a constant light distance by way of a differential control element and a control shifting device; the control shifting device thereby includes a control rod engaging at the pivotal headlight which in case of pressure failure is clamped fast either directly or indirectly by a servo-adjusting motor which is operatively connected with the pressure line.
