In the case of a dipped-beam headlamp, the illuminating surface is limited by the apparent trace of the cut-off on to the lens.
a single independent passing-beam headlamp may be fitted above, below or to one side of another front lamp.
The result expressed in milliradians (mrad) shall be considered as acceptable for a passing-beam headlamp when the absolute value Δ r1
In the case of a passing-beam headlamp, the illuminating surface is limited by the apparent trace of the cut-off on to the lens.
a single independent passing-beam headlamp which is reciprocally incorporated with another front lamp shall be fitted in such a way that its reference centre lies within the longitudinal median plane of the vehicle.
No point on the illuminating surface shall be higher than the highest point on the illuminating surface of the passing-beam headlamp.

The driving beam filament is correctly positioned relative to the passing beam filament.
is diameter of the passing beam filament and d2 that of the driving beam filament.
low beam headlamp (including adaptative front lighting system)
In order to improve the light beam range when using the driving light, the range of the light beam projected as driving light by the low beam headlamp (12) is extended as compared with the range of said low beam headlamp when the latter functions as such.
The light source of the low beam headlamp is a discharge lamp (18), and that of the high beam headlamp is an incandescent-filament lamp (24).
Category 11a for use at a distance not less than 40 mm from the passing beam headlamp
Category 11b for use at a distance not less than 20 mm from the passing beam headlamp
Category 11 for use at a distance not less than 75 mm from the passing beam headlamp
Category 11c for use at a distance less than 20 mm from the passing beam headlamp.
