Description
IThe vertical direction of the headlamp projection can be adjusted from inside the vehicle to prevent the
headlamp beam axis from facing upward due to a change in the number of occupants and load conditions
in the vehicle.
I A little Electronic Control Unit (ECU) is incorporated in each actuator (one for each headlamp), which
compares a signal voltage (V
signal), coming from the headlamp aiming switch, with battery voltage (12V).
The signal voltage varies with the position of the switch.
Related to the difference in voltage the actuator rod will move more or less and adjust the headlamp beam
angle accordingly.
