7.1
Vehicles on which the upper edge of the headlamps is
more than 140 cm above the floor
NOTE
National road traffic regulations must always be heeded.
1. The vehicle is placed on a level surface, which does not have to be horizontal, and at a distance of 10 metres from
a vertical, light-coloured wall.
2. The following lines have to be drawn on the wall:
•
Line A:
Extrapolate the longitudinal axis of the vehicle to the test wall and mark it with a vertical line.
•
Lines B und C:
Measure the distance X (centre- to-centre distance between the vehicle headlamps) and mark it on the wall
symmetrically to Line A.
•
Line D:
Draw this line at a distance ‘e’ below Line H. For headlamps „e” = H/3 cm, For fog lamps „e” = H/3 + 7 cm
•
Line H:
Measure height of centre of headlamps above the surface the vehicle is standing on - draw a line at this height
on the test wall parallel to the ground.
Adjusting headlamps
1. Cover the nearside headlamp and adjust the offside one so that the horizontal part of the cut-off line touches Line D.
2. Then adjust the headlamp left to right.
The angle separating the horizontal from the sloping part of the cut-off line must lie on Line B.
3. Then adjust the nearside headlamp in the same way.
The angle in the cut-off line must lie on Line C in this case. (The wall illustrated is correct for left-hand drive -
mirror-image applies for right-hand drive.)
