Headlamp Beam Adjustment

Some models for certain markets are equipped with a headlamp beam adjustment system.

By means of a switch on the dashboard the driver can change the vertical alignment of the headlamps. This avoids dazzling the drivers of oncoming vehicles when the car is heavily loaded.

With the ignition switch in the Drive position, terminal 9 of lights switch 282 is supplied with current via fuse 12.

With the switch in position 0 the headlamps are at their normal setting. When the switch is turned to position 1, electric motors 280FL and 280FR are supplied with current and rotate a certain number of revolutions (stepping motors). These motors act on the headlamp setting screws, lowering the setting of the headlamps by a certain amount. When the switch is turned to positions 2 and 3, the setting of the headlamps is lowered a further step or two.

In a similar manner, headlamp beam setting can be raised in steps through positions 3-2-1-0.
