Lateral adjustment


Switch on the headlamps (dipped) and check that the headlamp is correctly aligned laterally. The zone with the brightest light should be as close to the centre as possible.

For optimum alignment, the tolerance band for the light/dark boundary can be used.

Align both headlamps in the same way.

Check the spread of the main beam if there are problems with headlamp adjustment. Also check the bulb fittings.

Vertical adjustment


Switch on the headlamps (dipped) and check that the headlamp is correctly aligned vertically. Adjust the height of the beam to the left-hand (LHD cars) or right-hand (RHD cars) horizontal line.

Adjust vertically only to that part of the light/dark boundary that is 0-30 mm to the left (LHD) alternatively the right (RHD) of the centre line.

Align both headlamps in the same way.

Check the spread of the main beam if there are problems with headlamp adjustment.

Check the following points before carrying out adjustment.


• Check that the tyre pressures are correct.

• Check that the car is weighted with a normal load.

• Check that the bulbs are correctly fitted.

Position the car at right angles to the headlamp aligning equipment.
