Headlamp Beam Adjustment

Headlamp Beam Adjustment
Some models for certain markets are equipped with a headlamp beam adjustment system. The driver can adjust the setting of the headlamps using the switch on the dashboard. This avoids dazzling the drivers of other vehicles when the car is heavily loaded.

With the ignition switch in the Drive position, current is supplied to terminal 9 on light switch 282 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 280 and 281 are supplied with current and rotate a number of turns (stepping motors). These motors actuate the setting screws and the setting of the headlamps is lowered. When the switch is turned to positions 2 and 3, the setting is lowered a further two steps.

The beam setting is raised in steps in the same way, 3-2-1-0.
