Headlight Leveling

General Description

The circuit consists of the headlight leveling SW and
headlight leveling actuators. The actuator is made
up of a motor, two relays and disk-type sensor. The
sensor rotates in accordance with the rotation of the
motor and stops the rotation of the motor at each
position corresponding to the levels 0 to 3.
