♦ The horizontal light-dark border should coincide with the set‐
ting line -1- of the test surface.
♦ The break-away point -2- between the horizontal section of the
light-dark border on the left and the rising section on the right
should coincide with the vertical line running through the cen‐
tral point -3-. The bright spot in the centre of the beam should
be to the right of the vertical line.
Note
♦ To make it easier to find the break-away point -2-, cover and
uncover the left half of the headlight (as seen in direction of
travel) a few times. Then check the dipped beam again.
♦ If dipped beams have been adjusted correctly the centre point
of the main beam should lie on central point -3-.
♦ If using an old test screen with a 15 ° setting line, the adjust‐
ment procedure is the same as for the new screen. Disregard
the 15° setting line to avoid incorrect settings.
– If headlight setting is not OK, adjust headlights ⇒ page 182 .
