within the medium longitudinal plane of the vehicle; if these lamps are side by side their reference centre must be symmetrical in relation to the median longitudinal plane of the vehicle.

       6.1.3.1.2.  a driving lamp that is reciprocally incorporated with another front lamp must be fitted in such a way that its reference centre lies within the median longitudinal plane of the vehicle; however, when the vehicle is also fitted with an independent passing lamp alongside the driving lamp their reference centres must be symmetrical in relation to the median longitudinal plan of the vehicle.

       6.1.3.1.3. two driving lamps of which either one or both are reciprocally incorporated with another front lamp must be fitted in such a way that their reference centres are symmetrical in relation to the median longitudinal plane of the vehicle.

       6.1.3.2. The length: at the front of the vehicle. This requirement is regarded as satisfied if the light emitted does not cause discomfort to the driver either directly or indirectly by means of the rear-view mirrors and/or reflective surfaces on the vehicle.

       6.1.3.3.  In any case, the distance between the edge of the illumination surface of any independent driving lamp and the edge of that of the passing lamp must not exceed 200 mm.

       6.1.3.4.  In the case of two driving lamps: the distance separating the illuminating surfaces of two driving lamps must not exceed 200mm."

       6.1.4.  Geometric visibility

        The visibility of the illuminating surface, including its visibility in areas which do not appear to be illuminated in the direction of observation considered, shall be ensured within a divergent space defined by generating lines based on the perimeter of the illuminating surface and forming an angle of not less than 5 degrees with the axis of reference of the headlamp.

       6.1.5.  Orientation

        Forwards. The lamp(s) may move with the steering angle.

       6.1.6.  May not be "combined" with any other lamp.

       6.1.7.  Electrical connections

        The passing beam(s) may remain illuminated with the driving beam(s).

       6.1.8.  "Circuit-closed" tell-tale

        Mandatory, non-flashing blue signal lamp.

       6.1.9.  Other requirements

        Aggregate maximum intensity of the driving beam headlamps which can be switched on simultaneously shall not exceed 225,000 cd. (The approval value).

       6.2. PASSING BEAM HEADLAMP

       6.2.1.  Number

        One or two.

       6.2.2.  Arrangement

        No special requirement.

       6.2.3.  Position

       6.2.3.1.  Width

       6.2.3.1.1.  an independent passing lamp may be installed above, below or to one side of another front lamp: if these lamps are one above the other the reference centre of the passing lamp must be located within the medium longitudinal plane of the vehicle; if these lamps are side by side their reference centre must be symmetrical in relation to the median longitudinal plane of the vehicle.

       6.2.3.1.2.  a passing lamp
