Abstract: This invention relates to a headlight tilting system for vehicles having pivotal frames, oscillatable via a linkage driven by an electric motor and circuitry in which a manual switch can be set to establish a circuit between the motor and a battery via contacts sliding on a first conductive portion of a rotatable member driven by the motor. Electric current flows to the motor until a second portion electrically isolated or portions reaches one of the contacts forming the circuit when the circuit is broken and a switching arrangement simultaneously short circuits the armature of the motor to stop rotation of the motor instantly thus stopping the oscillation of the frames in exactly the desired position.
