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 that is reciprocally incorporated with another front lamp must be installed 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 driving lamp alongside the passing lamp their reference centres must be symmetrical in relation to the median longitudinal plan of the vehicle.

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

       6.2.3.2.  Height: a minimum of 500mm and a maximum of 1,200mm above the ground.

       6.2.3.3.  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 of the vehicle.

       6.2.3.4.  In the case of two passing lamps the distance separating the illuminating surfaces must not exceed 200 mm."

       6.2.4.  Geometric visibility

        Defined by angles alpha and beta as specified in paragraph 2.11

        alpha = 15 degrees upwards and 10 degrees downwards;

        beta = 45 degrees to the left and to the right for a single lamp;

        beta = 45 degrees outwards and 10 degrees inwards for each pair of lamps.

        The presence of partitions or other items of equipment near the head-lamp shall not give rise to secondary effects causing discomfort to other road users.

       6.2.5.  Orientation

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

       6.2.5.2.  The vertical orientation of the passing beam shall remain between - 0.5 % and - 2.5 % of downward inclination for the conditions of loading "vehicle plus driver"[2/] and "manufacturer's maximum permitted load", the load being distributed in accordance with the manufacturer's specification for loading and for the adjustment of the suspension (if any) for these conditions of loading.

       6.2.5.3. The reference orientation corresponding to the "vehicle plus driver" shall be set between - 1 % and - 1.5 %. This pre-determined reference value shall be indicated on a plate on each vehicle.

       6.2.5.4.  If necessary, the vehicle shall be equipped with a device by means of which the orientation of the passing beam can be easily aligned for the load states mentioned in paragraph 6.2.5.2. above, without the need of tools.

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

       6.2.7.  Electrical connections
