requirements of the Regulation, the exact edges of any surface need not be determined. When referring to the distance between lamps, the position, as regards width, shall be determined from the inner edges of the apparent surface in the direction of the reference axis. Where the position, as regards width, clearly meets the requirements of the Regulation, the exact edges of any surface need not be determined.

       5.8.  In the absence of specific instructions, no lamps other than direction-indicator lamps and the vehicle-hazard warning signal shall be flashing lamps.

       5.9.  No red light shall be visible towards the front and no white light shall be visible towards the rear. Compliance with this requirement shall be verified as shown hereunder (see drawing in annex 4):

       5.9.1.  visibility of red light towards the front; a red lamp must not be directly visible to an observer moving in zone 1 of a transverse plane situated 25 m forward of the foremost point on the vehicle;

       5.9.2.  visibility of white light towards the rear: a white lamp must not be directly visible to an observer moving in zone 2 of a transverse plane situated 25 m rearward of the rearmost point on the vehicle;

       5.9.3.  in their respective planes, the zones 1 and 2 explored by the eye of the observer are bound:

       5.9.3.1.  in height, by two horizontal planes 1 m and 2.2 m respectively above the ground;

       5.9.3.2.  in width, by two vertical planes which, forming to the front and the rear respectively an angle of 15 degrees outwards from the vehicle's median longitudinal plane, pass through the point or points of contact of vertical planes parallel to the vehicle's median longitudinal plane and delimiting the vehicle's over-all width; if there are several points of contact, the foremost shall correspond to the forward plane and the rearmost to the rearward plane.

       5.10.  The electrical connections shall be such that the front position lamp or the passing beam headlamp, if there is no front position lamp, the rear position lamp and the rear registration-plate illuminating device cannot be switched on or off otherwise than simultaneously.

       5.11.  In the absence of specific instructions, the electrical connection shall be such that the driving beam headlamp, the passing beam headlamp and the fog lamp cannot be switched on unless the lamps referred to in paragraph 5.10. above are likewise switched on. This requirement need not, however, be satisfied in the case of the driving beam headlamp and passing beam headlamp where their luminous warnings consist in switching on the passing beam headlamp intermittently, at short intervals, or in switching on the driving beam headlamp intermittently, or in switching on the passing beam headlamp and driving-beam headlamp
