Headlamp Beam Setter / Inspection Station
Abbreviations used:
A = Horizontal distance between headlamp centres
B = Central marking
C = Test surface
C = Test surface
D = Road surface
E = Break point (kink of cut-off line)
e = Aiming dimension in cm, e = H - h (aiming dimension, low beam headlamps usually at 1.0 percent, e = 10 cm (4 in), front fog lamps 2.0 percent, e = 20 cm (8 in), high beam headlamps (if separately amiable) at 0 percent, e = 0 cm (0 in).
H = Height of centre of headlamp over road surface
h = Height of light/dark boundary line (cut-off line) of low beam above road surface
The headlamp aiming is performed according to the specifications, as shown in the illustrations, using an adjuster. When using a headlamp adjuster, set up the height and position of the adjuster according to the instructions in the operation manual. Ensure that the vehicle tire surface that is in contact with the road and the surface for setting up the adjuster are at the same level and parallel with each another.
X = Center of adjuster lens (see arrow mark on adjuster housing) must be aligned on the same level as the low beam headlamp and must be parallel to the ground.
1 = Use marking of the control mirror (1) to align the adjuster system in the correct angle to the vehicle, based on the information shown in the owner operating instructions.
The distance between the adjuster lens and the headlamp must be max. 0, 9 meters (refer to operation instructions of the adjuster system)
The surface on which the measuring instrument (adjuster system) and the vehicle stand must be flat. See follow table.
| I difference utility space from vehicle | |
|---|---|
| longitudinal direction | lateral direction |
| ± 3 mm / m | ± 0 mm / 1 m |
| ± 5 mm / 2m | ± 0 mm / 2 m |
| ± 7 mm /3 m | ± 0 mm / 3 m |
| ± 9 mm / 4 m | ± 0 mm / 4 m |

| longitudinal direction | lateral direction |
| ± 1 mm / 1 m | ± 1 mm / 1 m |
Vehicle tires must have specified air pressure. Blackened bulbs must be replaced before adjusting.
The adjustment is performed at vehicle curb weight plus one person or 75 kg (165 lb) on the driver's seat. (Curb weight = weight of vehicle ready for use with 90% filled fuel tank plus the weight of all equipment carried during use, e.g. spare wheel, tools, jack, first aid kit, emergency warning triangle, etc.).
