This Regulation applies to the approval of headlamps using filament lamps, producing one single passing beam, which are provided for the equipment of mopeds 1/ and vehicles treated as such.
For measurements, the measuring screen shall be located at a distance of 10 m in front of the headlamp and perpendicular to a line joining the filament of the lamp and the point HV; the line H-H shall be horizontal.
For lamps with transverse filament, the filament shall be as horizontal as possible during the measurements.

Laterally, the headlamps shall be so aimed that the beam is as symmetrical as possible with reference to the line V-V.

Vertically, the headlamp shall be so aimed that the illumination in point HV is 2 1x. Under those conditions, the cut-off shall be situated between the line H-H and the line H-100 mm.

When aimed according to paragraphs 2 and 3 above, the illumination shall meet the following values:

on the line H-H and above: 2 1x max.;

on a line situated 300 mm below H-H and over a width of 900 mm in both sides of the vertical line V-V: not less than 8 1x;

on a line situated 600 mm below the line H-H and over a width of 900 mm on both sides of the vertical line V-V: not less than 4 1x.
