                                       retro-reflecting number plates;
                                    
                                 
                                        
                                    
                                    
                                       other plates and retro-reflecting signals which must be used to comply with a Contracting Party’s specifications for use as regards certain categories of vehicles or certain methods of operation.

                           ‘Illuminating surface of a lighting device’ (paragraphs 2.5.8 to 2.5.11) means the orthogonal projection of the full aperture of the reflector in a transverse plane. If the lamp glass (or glasses) extend(s) over part only of the full aperture of the reflector, then the projection of that part only is taken into account. In the case of a passing lamp, the illuminating surface is limited on the side of the cut-off by the apparent projection of the line of the cut-off on to the lens. If the reflector and glass are adjustable, the mean adjustment should be used;
                        
                     
                           2.6.2.
                        
                        
                           ‘Illuminating surface of a signalling lamp other than a retro reflector’ (paragraphs 2.5.12 to 2.5.20) means the orthogonal projection of the lamp in a plane perpendicular to its axis of reference and in contact with the exterior light-emitting surface of the lamp, this projection being bounded by the edges of screens situated in this plane, each allowing only 98 % of the total luminous intensity of the light to persist in the direction of the axis of reference. To determine the lower, upper and lateral limits of the illuminating surface, only screens with horizontal or vertical edges shall be used;
                        
                     
                           2.6.3.
                        
                        
                           ‘Illuminating surface of a reflex reflector’ (paragraph 2.5.22) means the orthogonal projection of the reflecting surface of the retro reflector in a plane perpendicular to its axis of reference and bounded by planes touching the outer edges of the light projection surface of the retro reflector and parallel to this axis. To determine the lower, upper and lateral limits of the illuminating surface, only vertical and horizontal planes shall be used;
                        
                     
                           2.6.4.
                        
                        
                           ‘Light-emitting surface’ means that part of the exterior surface of the transparent lens that encloses the lighting or light-signalling device and allows it to emit light.
                        
                     
         
               2.7.
            
            
               ‘Apparent surface’ for a defined direction of observation, means the orthogonal projection of the light-emitting surface in a plane perpendicular to the direction of observation (see Annex 3).
            
         
               2.8.
            
            
               ‘Axis of reference’ means the characteristic axis of the light signal determined by the manufacturer of the lamp for use as the direction of reference (H = 0°, V = 0°) for photometric measurements and when fitting the lamp on the tractor.
            
         
               2.9.
            
            
               ‘Centre of reference’ means the intersection of the axis of reference with the exterior light-emitting surface, specified by the manufacturer of the lamp.
            
         
               2.10.
            
            
               ‘Angles of geometric visibility’ means the angles which determine the field of the minimum solid angle in which the apparent surface of the lamp must be visible. That field of the solid angle is determined by the segments of the sphere of which the centre coincides with the centre of reference of the lamp and the equator is parallel with the ground. These segments are determined in relation to the axis of reference. The horizontal angles ß correspond to the longitude and the vertical angles α to the latitude. There must be no obstacle on the inside of the angles of geometric visibility to the propagation of light from any part of the apparent surface of the lamp observed from infinity. If measurements are taken closer to the lamp, the direction of observation must be shifted parallel to achieve the same accuracy.
               On the inside of the angles of geometric visibility no account is taken of obstacles, if they were already presented when the lamp was type-approved.
               If, when the lamp is installed, any part of the apparent surface of the lamp is hidden by any further parts of the vehicle, proof shall be furnished that the part of the lamp not hidden by obstacles still conforms to the photometric values prescribed for the approval of the device as an optical unit (see explanatory figure below).

               have substantially identical photometric characteristics.
            
         5.6.   On tractors whose external shape is asymmetrical, the requirements of paragraphs 5.5.1 and 5.5.2 shall be satisfied as far as possible. These requirements shall be regarded as having been met if the distance of the two lamps from the median longitudinal plane and from the bearing plane on the ground is the same.
   5.7.   Lamps having different functions may be independent or be grouped, combined or reciprocally incorporated in one device, provided that each such lamp complies with the requirements applicable to it.
   5.8.   The maximum height above ground shall be measured from the highest point and the minimum height from the lowest point of the illuminating surface. In the case of passing lamps, the minimum height in relation to the ground is measured from the lowest edge of the reflector.
   5.9.   In the absence of specific instructions, no lamps other than direction-indicator lamps and the hazard warning signal shall be flashing lamps.
   5.10.   No red light shall be visible towards the front and no white light other than that from the reversing lamp or work lamps shall be visible towards the rear.
   This requirement is considered to have been met if:
   
               5.10.1.
            
            
               for the visibility of a red light towards the front; there is no direct visibility of a red lamp if its light-emitting surface is viewed by an observer moving within zone 1 in a transverse plane situated 25 m in front of the tractor (see Annex 4, figure 1);
            
         
               5.10.2.
            
            
               for the visibility of a white light towards the rear; there is no direct visibility of a white lamp if its light-emitting surface is viewed by an observer moving within zone 2 in a transverse plane situated 25 m behind the tractor (see Annex 4, figure 2);
            
         
               5.10.3.
            
            
               Zones 1 and 2, as seen by the observer, are limited in their respective planes as follows:
               
                           5.10.3.1.
                        
                        
                           as regards height, by two horizontal planes which are 1 m and 2,2 m respectively above the ground;
                        
                     
                           5.10.3.2.
                        
                        
                           as regards width, by two vertical planes which make an angle of 15° towards the front and rear respectively, and towards the outside by reference to the median plane of the tractor, passing through the point (or points) of contact of vertical planes which are parallel with the median longitudinal plane of the tractor, and limiting the overall width of the tractor when on wide track.
                           If there are several points of contact, the one furthest towards the front shall be selected for zone 1 and the one furthest towards the rear shall be selected for zone 2.
                        
                     
         5.11.   The electrical connections must be such that the front and rear position (side) lamps, the end-outline marker lamps if they exist, and the rear registration plate lamp can only be switched on and off simultaneously.
   This is not valid when using front and rear position (side) lamps as parking lamps.
   5.12.   The electrical connections must be such that the driving lamps and passing lamps, and the front and rear fog lamps cannot be switched on unless the lamps referred to in paragraph 5.11 are also switched on. This requirement shall not apply, however, to driving lamps or passing lamps when their luminous warnings consist of the intermittent lighting up at short intervals of the passing lamps or the intermittent lighting up of the driving lamps or the alternate lighting up at short intervals of the passing lamps and driving lamps.
   The function of the circuit-closed tell-tales may be fulfilled by operational tell-tales.
   5.13.   Concealable lamps.
   
               5.13.1.

               5.13.2.2.
            
            
               Accidental opening of the supply circuit, earth leakage, defect in solenoids, defects in the hydraulic or compressed air lines, Bowden cables, flexible leads or other components controlling or transmitting the energy intended to actuate the concealment device;
            
         
               5.13.3.
            
            
               In the event of a defect in the concealment control, or other defects referred to in paragraphs 5.13.2.1 and 5.13.2.2 above, a concealed lighting device shall be capable of being moved into the positions of use without the aid of tools;
            
         
               5.13.4.
            
            
               Illuminating devices which are manipulated by power shall be brought into the position of use and switched on by means of a single control, without excluding the possibility of moving them into the position of use without switching them on. However, in the case of grouped-driving lamps and passing lamps, the control referred to above is required only to activate the passing lamps;
            
         
               5.13.5.
            
            
               It must not be possible deliberately, from the driver’s seat, to stop the movement of switched-on headlamps before they reach the position of use. If there is a danger of dazzling other road users by the movement of headlamps, they may light up only when they have reached their final position;
            
         
               5.13.6.
            
            
               At temperatures of – 30 °C to + 50 °C an illuminating device which is manipulated by power must be capable of reaching the position of use within three seconds of initial operation of the control.

               Mandatory for all direction-indicator lamps not directly visible to the driver. It may be optical or auditory or both.
               If it is optical, it shall be a flashing light which, in the event of the malfunction of any of the direction-indicator lamps other than the repeating side direction-indicator lamps, is either extinguished, or remains alight without flashing, or shows a marked change of frequency. If it is entirely auditory, it shall be clearly audible and shall show a marked change of frequency in the event of any malfunction.
               If a tractor is equipped to tow a trailer, it must be equipped with a special optical operational tell-tale for the direction indicator lamps on the trailer unless the tell-tale of the drawing vehicle allows the failure of any one of the direction-indicator lamps on the tractor combination thus formed to be detected.

               If a tractor is authorised to tow a trailer, the control of the direction-indicators on the tractor shall also operate the indicators of the trailer.
               In the event of failure, other than a short circuit, of one direction-indicator, the others must continue to flash but the frequency under this condition may be different from that specified.
