'Vehicle type with regard to the installation of lighting and light-signalling devices`means  vehicles which do not differ in the essential respects mentioned in items 1.1.1 to 1.1.4. The following are likewise considered not to be 'vehicles of a different type`: vehicles which  differ within the meaning of items 1.1.1 to 1.1.4, but not in such a way as to entail a change in  the kind, number, positioning and geometric visibility of the lamps and the inclination of the  dipped beam prescribed for the vehicle type in question, and vehicles on which optional lamps are  fitted or are absent; 1.1.1. the dimensions and the external shape of the vehicle; 1.1.2. the number and positioning of the devices; 1.1.3. the headlamp-levelling system; 1.1.4. the suspension system. 1.2. 'Transverse plane`means a vertical plane perpendicular to the median longitudinal plane of the  vehicle. 1.3. 'Unladen vehicle`means the vehicle in running order, as defined in item 2.6 of Annex I, model  information document, to Directive 70/156/EEC, but without driver. 1.4. 'Laden vehicle`means the vehicle loaded to its technically permissible maximum mass, as stated by  the manufacturer, who shall also fix the distribution of this mass between the axles in accordance  with the method described in Appendix 1. 1.5. 'Device`means an element or an assembly of elements used to perform one or more functions. 1.6. 'Light source with regard to filament lamps`means the filament itself. (Where a lamp has several  filaments, each one shall constitute a light source). 1.7. 'Lamp`means a device designed to illuminate the road or to emit a light signal. Rear registration  plate lamps and retro reflectors are likewise regarded as lamps. 1.7.1. 'Equivalent lamps`means lamps having the same function and authorized in the country in which the  vehicle is registered; such lamps may have different characteristics from those installed on the  vehicle when it is approved on condition that they satisfy the requirements of this Annex. 1.7.2. 'Single-function lamp`means a part of a device which performs a single lighting or  light-signalling function. 1.7.3. 'Independent lamps` (1)means devices having separate illuminating surfaces, separate light sources  and separate lamp bodies. (;) In the case of lighting devices for the rear number plate and the direction indicators  (category 5), replace 'illuminating surface` by 'light-emitting surface` in the absence of an  illuminating surface. 1.7.4. 'Grouped lamps` (¹)means devices having separate illuminating surfaces and separate light sources,  but a common lamp body. 1.7.5. 'Combined lamps` (¹)means devices having separate illuminating surfaces, but a common light source  and a common lamp body. 1.7.6. 'Reciprocally incorporated lamps` (¹)Means devices having separate light sources or a single light  source operating under different conditions (e.g. optical, mechanical or electrical differences),  totally or partially common illuminating surfaces and a common lamp body. 1.7.7. 'Concealable lamp`means a lamp capable of being partly or completely hidden when not in use. This  result may be achieved by means of a movable cover, by displacement of the lamp or by any other  suitable means. The term 'retractable` is used more particularly to describe a concealable lamp,  the displacement of which enables it to be inserted within the bodywork. 1.7.8. 'Main-beam headlamp`means the lamp used to illuminate the road over a long distance ahead of the  vehicle. 1.7.9. 'Dipped-beam headlamp`means the lamp used to illuminate the road ahead of the vehicle without  causing undue dazzle or discomfort to oncoming drivers and other road-users. 1.7.10. 'Front fog lamp`means the lamp used to improve the illumination of the road in case of fog,  snowfall, rainstorms or dust clouds. 1.7.11. 'Reversing lamp`means the lamp used to illuminate the road to the rear of the vehicle and to warn  other road-users that the vehicle is reversing or about to reverse. 1.7.12. 'Direction indicator lamp`means the lamp used to indicate to other road-users that the driver  intends to change direction to the right or to the left. 1.7.13. 'Hazard warning signal`means the simultaneous operation of all of a vehicle's direction indicator  lamps to draw attention to the fact that the vehicle temporarily constitutes a special danger to  other road-users. 1.7.14. 'Stop lamp`means the lamp used to indicate to other road-users to the rear of the vehicle that the  latter's driver is applying the service brake. 1.7.15.

'Front position lamp`means the lamp used to indicate the presence and the width of the vehicle  when viewed from the front. 1.7.17. 'Rear position lamp`means the lamp used to indicate the presence and the width of the vehicle when  viewed from the rear. 1.7.18. 'Rear fog lamp`means the lamp used to render the vehicle more readily visible from the rear in  dense fog. (;) In the case of lighting devices for the rear number plate and the direction indicators  (category 5), replace 'illuminating surface` by 'light-emitting surface` in the absence of an  illuminating surface. 1.7.19. 'Parking lamp`means the lamp used to draw attention to the presence of a stationary vehicle in a  built-up area. In such circumstances it replaces the front and rear position lamps. 1.7.20. 'End-outline marker lamp`means the lamp fitted to the extreme outer edge as close as possible to  the top of the vehicle and intended clearly to indicate the vehicle's overall width. This lamp is  intended, for certain vehicles and trailers, to complement the vehicle's front and rear position  lamps by drawing particular attention to its bulk. 1.7.21. 'Side-marker lamp`means a lamp used to indicate the presence of the vehicle when viewed from the  side. 1.7.22. 'Retro reflector`means a device used to indicate the presence of a vehicle by the reflection of  light emanating from a light source not connected to the vehicle, the observer being situated near  the source. For the purposes of this Directive the following are not considered as retro reflectors: - retro-reflecting number plates, - the retro-reflecting signals mentioned in the ADR (European Agreement concerning the  international carriage of dangerous goods by road), - other retro-reflecting plates and signals which must be used to comply with a Member State's  specifications for use as regards certain categories of vehicles or certain modes of operation. 1.8. 'Light-emitting surface`means all or part of the exterior surface of the translucent material  which helps to confer on the light its particular photometric and colorimetric properties. When  only part of the exterior surface emits light, the light-emitting surface shall, in case of doubt,  be specified by the competent authority after consultation with the vehicle and/or component  manufacturer. 1.9. Illuminating surfaces1.9.1. 'Illuminating surface of a lighting device` (Item 1.7.8 to 1.7.11)means the orthogonal projection  of the full aperture of the reflector in a transverse plane. If the lighting device has no  reflector, the definition of item 1.9.2 shall be applied. If the light-emitting surface of the lamp  extends over a 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 dipped-beam headlamp, the illuminating surface is limited by the apparent trace of  the cut-off on to the lens. If the reflector and lens are adjustable relative to one another, the  mean adjustment should be used. 1.9.2. 'Illuminating surface of a signalling lamp other than a retro reflector` (Items 1.7.12 to  1.7.21)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 the 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. 1.9.3. 'Illuminating surface of a retro reflector` (Items 1.7.22)means the illuminating surface of a  retro reflector in a plane perpendicular to the 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. 1.10. '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 drawing in  Appendix 2) and tangential to the most exterior point of the lens. 1.11. 'Axis of reference`means the characteristic axis of the light signal, determined by the  manufacturer for use as the direction of reference (H = 0o, V = 0o) for angles of field for  photometric measurements and when fitting the lamp on the vehicle. 1.12. 'Centre of reference`means the intersection of the axis of reference with the light-emitting  surface. This centre of reference is to be specified by the manufacturer of the lamp. 1.13. '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 â correspond to the longitude and the vertical  angles á 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, there must be a parallel shift in the direction of  observation to achieve the same accuracy. N° account shall be taken of obstacles on the inside of the angles of geometric visibility, if they  were already present 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 figure below). 1.14. 'Extreme outer edge`on either side of the vehicle means the plane parallel to the median  longitudinal plane of the vehicle and touching its lateral outer edge, disregarding the  projection: 1.14.1. of tyres near their point of contact with the ground and connections for tyre pressure gauges; 1.14.2. of anti-skid devices which may be mounted on the wheels; 1.14.3. of rear-view mirrors; 1.14.4. of side direction indicator lamps, end-outline marker lamps, front and rear position lamps, parking  lamps, retro reflectors and side-marker lamps; 1.14.5. of customs seals affixed to the vehicle and devices for securing and protecting such seals. 1.15. 'Overall width`means the distance between the two vertical planes defined in item 1.14. 1.16. A 'single lamp`means a device or part of a device, having one function and one illuminating  surface and one or more light sources. For the purpose of installation on a vehicle, a 'single  lamp` also means any assembly of two independent or grouped lamps, whether identical or not, having  the same function, if they are installed such that the projections of the illuminating surfaces of  the lamps on a given transverse plane occupy not less than 60 % of the smallest rectangle  circumscribing the projections of the said illuminating surfaces. In such a case, each of these lamps shall, where approval is required, be approved as a type 'D`  lamp. This possible combination does not apply to main-beam headlamps, dipped-beam headlamps and  front fog lamps. 1.17. 'Two lamps or an even number of lamps`means a single light-emitting surface in the shape of a band  if placed symmetrically in relation to the median longitudinal plane of the vehicle and extending  on both sides to within not less than 400 mm of the extreme outer edge of the vehicle, and being  not less than 800 mm long. The illumination of such a surface shall be provided by not less than  two light sources placed as close as possible to its ends. The light-emitting surface may be  constituted by a number of juxtaposed elements on condition that the projections of the several  individual light-emitting surfaces on the same transverse plane occupy not less than 60 % of the  area of the smallest rectangle circumscribing the projections of those individual light-emitting  surfaces. 1.18. 'Distance between two lamps`which face in the same direction means the shortest distance between  the orthogonal projections in a plane perpendicular to the axes of reference of the outlines of the  two illuminating surfaces as defined according to the case mentioned in item 1.9. The distance  between two lamps may, however, be measured without determining the outlines of the illuminating  surfaces exactly, where the distance is clearly in excess of the minimum requirements of the  Directive. 1.19. 'Optional lamp`means a lamp the presence of which is left to the discretion of the vehicle  manufacturer. 1.20. 'Operational tell-tale`means a light or auditory device showing whether a device that has been  actuated is operating correctly or not. 1.21. 'Circuit-closed tell-tale`means a light showing that a device has been switched on but not showing  whether it is operating correctly or not. 1.22. 'Ground`means the surface on which the vehicle stands, which should be substantially horizontal. 1.23. 'Movable components`of the vehicle means those body panels or other vehicle parts, the position of  which can be changed by tilting, rotating or sliding without the use of tools. They do not include  tiltable driver cabs. 1.24. 'Normal position of use of a movable component`means the position(s) of a movable component  specified by the vehicle manufacturer for the normal condition of use and the park condition of the  vehicle. 1.25. 'Normal condition of use of a vehicle`means: 1.25.1. for a motor vehicle, when the vehicle is ready to move with its propulsion engine running and its  movable components in the normal position(s) as defined in item 1.24; 1.25.2. and for a trailer, when the trailer is connected to a drawing vehicle in the condition as described  in item 1.25.1 and its movable components are in the normal position(s) as defined in item 1.24. 1.26. 'Park condition of a vehicle`means: 1.26.1. for a motor vehicle, when the vehicle is at a standstill and its propulsion engine is not running  and its movable components are in the normal position(s) as defined in item 1.24; 1.26.2. and for a trailer, when the trailer is connected to a drawing vehicle in the condition as described  in item 1.26.1 and its movable components are in the normal position(s) as defined in item 1.24. 2. APPLICATION FOR EC TYPE-APPROVAL2.1. The application for EC approval of a vehicle type with regard to the installation of its lighting  and light-signalling devices shall be submitted by the vehicle manufacturer or his representative. 2.2. It shall be accompanied by the following documents in triplicate, and by the following  particulars: 2.2.1. a description of the vehicle type in accordance with the points listed in 1.1, together with the  restrictions on loading, particularly the maximum permissible load in the boot; 2.2.2. a list of devices prescribed by the manufacturer for the lighting and light-signalling assembly.  The list may include several types of device for each operation. Each type must be duly identified  (component type-approval mark, name of manufacturer, etc.); 2.2.3. layout drawing of the lighting and light-signalling equipment as a whole, showing the position of  the various lamps on the vehicle; 2.2.4. if necessary, in order to verify conformity to the requirements of the present Directive, layout  drawing(s) for each individual lamp showing the illuminating surface as defined in items 1.9.1,  1.9.2 and 1.9.3, the light-emitting surface as defined in item 1.8, the axis of reference as  defined in item 1.11 and the centre of reference as defined in item 1.12. This information is not  necessary in the case of the rear registration plate lamp (item 1.7.15). 2.3. An unladen vehicle fitted with lighting and light-signalling equipment as described in item 2.2.2  and representative of the vehicle type to be approved, must be submitted to the technical authority  conducting approval tests. 2.4. The document provided for in Annex II shall be attached to the type-approval document. 3. GENERAL SPECIFICATIONS3.1. Without prejudice to the provisions of this Annex, solely the installation of the lighting and  light-signalling devices defined in items 1.7.8 to 1.7.22 shall be permitted. The installation of  any other lighting or light-signalling device is consequently prohibited. 3.2. The lighting and light-signalling devices must be so fitted that under normal conditions of use as  defined in items 1.25, 1.25.1 and 1.25.2, and notwithstanding any vibration to which they may be  subjected, they retain the characteristics laid down in this Annex and enable the vehicle to comply  with the requirements of this Annex. In particular, it shall not be possible for the adjustment of  the lamps to be inadvertently disturbed. 3.3. The illuminating lamps described in items 1.7.8, 1.7.9 and 1.7.10 must be so fitted that a correct  setting of their alignment can easily be performed. 3.4. For all light-signalling devices, including those mounted on the side panels, the reference axis of  the lamp when fitted to the vehicle must be parallel to the bearing plane of the vehicle on the  road; in addition it must be perpendicular to the median longitudinal plane of the vehicle in the  case of side retro reflectors and of side-marker lamps and parallel to that plane in the case of  all other signalling devices. In each direction a tolerance of p 3o shall be allowed. In addition,  any specific instructions as regards fitting laid down by the manufacturer must be complied with. 3.5. In the absence of specific requirements, the height and alignment of the lamps shall be checked  with the unladen vehicle placed on a flat, horizontal surface under the conditions defined in items  1.25, 1.25.1 and 1.25.2. 3.6. In the absence of specific requirements, lamps constituting a pair shall: 3.6.1. be fitted to the vehicle symmetrically in relation to the median longitudinal plane (this estimate  to be based on the exterior geometrical form of the lamp and not on the edge of its illuminating  surface referred to in items 1.9.1, 1.9.2 and 1.9.3); 3.6.2. be symmetrical to one another in relation to the median longitudinal plane; this requirement is not  valid with regard to the interior structure of the lamp; 3.6.3. satisfy the same colorimetric characteristics; 3.6.4. have substantially identical photometric characteristics. 3.7. On vehicles whose external shape is asymmetrical, the above requirements shall be satisfied as far  as possible. 3.8. 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. 3.9. 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 dipped headlamps, the minimum height in relation to the ground is measured from the  lowest edge of the reflector. 3.9.1. The position, as regards width, shall be determined from the edge of the illuminating surface which  is the furthest from the median longitudinal plane of the vehicle when referred to the overall  width, and from the inner edges of the illuminating surfaces when referred to the distance between  the lamps. 3.10. In the absence of specific requirements no lamps other than direction indicator lamps and the  hazard warning signal may emit a flashing light. 3.11. N° red light which could give rise to confusion shall be emitted from a lamp as defined in item 1.7  in a forward direction and no white light which could give rise to confusion, other than from the  reversing lamp, shall be emitted from a lamp as defined in item 1.7 in a rearward direction. N°  account shall be taken of lighting devices fitted in the interior of the vehicle. In case of doubt,  this requirement shall be verified as follows: 3.11.1. for the visibility of red light towards the front: there must be no direct visibility of the  light-emitting surface of a red lamp if viewed by an observer moving within Zone 1 in a transverse  plane situated 25 m in front of the vehicle (see Appendix 3, Figure 1); 3.11.2. for the visibility of white light towards the rear: there must be no direct visibility of the  light-emitting surface of a white lamp if viewed by an observer moving within Zone 2 in a  transverse plane situated 25 m behind the vehicle (see Appendix 3, Figure 2). 3.11.3. Zones 1 and 2, as seen by the observer, are limited in their respective planes as follows: 3.11.3.1. as regards height, by two horizontal planes which are 1 and 2.2 m respectively above the ground; 3.11.3.2. as regards width, by two vertical planes which make an angle of 15o towards the front and rear  respectively, and outside the vehicle by reference to the median plane of the vehicle, passing  through the point (or points) of contacts of vertical planes which are parallel to the median  longitudinal plane of the vehicle, and limiting the overall width of the vehicle. If there are several points of contact, the one which is furthest forward shall correspond to the  front plane and the one furthest rearward shall correspond to the rear plane. 3.12. The electrical connections must be such that the front and rear position lamps, the end-outline  marker lamps, where fitted, the side-marker lamps, where fitted, and the rear registration plate  lamp can only be switched on and off simultaneously. This requirement shall not apply when using front and rear position lamps, as well as side-marker  lamps combined or reciprocally incorporated with said lamps, as parking lamps. 3.13. The electrical connections must be such that the main-beam and dipped-beam headlamps and the front  fog lamps cannot be switched on unless the lamps referred to in item 3.12 are also switched on.  This requirement shall not apply, however, to main-beam or dipped-beam headlamps when their  luminous warnings consist of the intermittent lighting up at short intervals of the main-beam  headlamp or the intermittent lighting up at short intervals of the dipped-beam headlamp or the  alternate lighting up at short intervals of the main-beam and dipped-beam headlamps.  3.14. The colours of the light emitted by the lamps are the following: - main-beam headlamp: white- dipped-beam headlamp: white- front fog lamp: white or yellow- reversing lamp: white- direction indicator lamp: amber- hazard warning signal: amber- stop lamp: red- rear registration plate lamp: white- front position lamp: white- rear position lamp: red- rear fog lamp: red- parking lamp: white in front, red at the rear, amber if incorporated in the side direction indicator lamps or in  the side-marker lamps- side-marker lamp: amber; however, it may be red if the rearmost side-marker lamp is grouped or combined or  reciprocally incorporated with the rear position lamp, the rear end-outline marker lamp, the rear  fog lamp, the stop lamp or is grouped or has part of the light-emitting surface in common with the  rear retro reflector- end-outline marker lamp: white in front, red at the rear- rear retro reflector, non-triangular: red- rear retro reflector, triangular: red- front retro reflector, non-triangular (1): identical to incident light- side retro reflector, non-triangularamber; however, it may be red if  the rearmost side retro reflector is grouped or has part of the light-emitting surface in common  with the rear position lamp, the rear end-outline marker lamp, the rear fog lamp, the stop lamp or  the red rearmost side-marker lamp. 3.15. The function of the circuit-closed tell-tales may be fulfilled by operational tell-tales. 3.16. Concealable lamps3.16.1. The concealment of lamps shall be prohibited, with the exception of the main-beam headlamp, the  dipped-beam headlamp and the front fog lamp, which may be concealed when not in use. 3.16.2. In the event of any failure affecting the operations of the concealment device(s) the lamps shall  remain in the position of use, if already in use, or shall be capable of being moved into the  position of use without the aid of tools. 3.16.3. It must be possible to move the lamps into the position of use and to switch them 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 main-beam and dipped-beam headlamps, the control referred to above  is required only to activate the dipped-beam headlamps. 3.16.4. It must not be possible deliberately, from the driver's seat, to stop the movement of switched-on  lamps before they reach the position of use. If there is a danger of dazzling other road users by  the movement of the lamps, they may light up only when they have reached their position of use. 3.16.5. At temperatures of  30 to +50 oC a lamp must be capable of reaching the position of use within  three seconds of initial operation of the control. 3.17. Number of lampsThe number of lamps mounted on the vehicle shall be equal to the number(s)  specified in subitem 2 of items 4.1 to 4.18. 3.18. Except as provided by items 3.19, 3.20 and 3.22, lamps may be installed on movable components. 3.19. Rear position lamps, rear direction indicator lamps and rear retro reflectors, triangular as well  as non-triangular, must not be installed on movable components. Should the above functions be  obtained by an assembly of two lamps marked 'D` (see item 1.16), only one of these lamps need be  installed on the non-movable part of the vehicle. 3.20. There must not be any movable component, with or without a light signalling device installed on it,  which in any fixed position hides more than 50 % of the apparent surface of front and rear position  lamps, front and rear direction indicator lamps and retro reflectors when viewed in a direction  parallel to the longitudinal axis of the vehicle. If this is not practicable: 3.20.1. a remark in item 16 of the document in Annex II shall inform other administrations that more than  50 % of the apparent surface can be hidden by the movable components; 3.20.2. in the case of item 3.20.1 a notice in the vehicle shall inform the user that in certain  position(s) of the movable components other road users shall be warned of the presence of the  vehicle on the road; for example by means of a warning triangle or other devices according to  national requirements for use on the road. 3.21. When the movable components are in a position other than a 'normal position` as defined in item  1.24 the devices installed on them shall not cause indue discomfort to road users. 3.22. When a lamp is installed on a movable component and the movable component is in the normal  position(s) of use (see item 1.24), the lamp must always return to the position(s) specified by the  manufacturer in accordance with this Annex. In the case of dipped-beam headlamps and front fog  lamps, this requirement shall be considered satisfied if, when the movable components are moved and  returned to the normal position 10 times, no value of the angle inclination of these lamps,  relative to its support, measured after each operation of the movable component, differs by more  than 0,15 % from the average of the 10 measured values. 3.23. Lamps may be grouped, combined or reciprocally incorporated with one another provided that all  requirements regarding colour, position, alignment, geometric visibility, electrical connections  and 'other requirements`, if any, for each lamp, are fulfilled. 3.24. With the exception of retro reflectors, a lamp even bearing an approval mark shall be deemed not to  be present when it cannot be made to operate by the sole installation of a filament lamp. 4. INDIVIDUAL SPECIFICATIONS4.1. Main-beam headlamps4.1.1. PresenceMandatory on motor vehicles. Prohibited on trailers. 4.1.2. NumberTwo or four.

ArrangementN° individual specifications. 4.1.4. Position4.1.4.1. Width: the outer edges of the illuminating surface must in no case be closer to the extreme outer edge of  the vehicle than the outer edges of the illuminating surface of the dipped-beam headlamps. 4.1.4.2. Height: no individual specifications. 4.1.4.3. Length: at the front of the vehicle and fitted in such a way that the light emitted does not cause  discomfort to the driver either directly or indirectly through the rear-view mirrors and/or other  reflecting surfaces of the vehicles. 4.1.5. Geometric visibilityThe visibility of the illuminating surface, including its visibility in areas  which do not appear to be illuminated in the direction of observation considered, must 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 5o with the axis of reference of the headlamp. The  origin of the angles of geometric visibility is the perimeter of the projection of the illuminating  surface on a transverse plane tangent to the foremost part of the lens of the headlamp. 4.1.6. AlignmentTowards the front. Apart from the devices necessary to maintain correct adjustment, and when there are two pairs of  headlamps, one pair, consisting of headlamps functioning as main-beam headlamps only may swivel,  according to the angle of lock of the steering, about an axis very near the vertical. 4.1.7. Electrical connections4.1.7.1. The main-beam headlamps may be switched on either simultaneously or in pairs. For changing over  from the dipped to the main beam at least one pair of main beams must be switched on. For changing  over from the main to the dipped beam all main-beam headlamps must be switched off simultaneously. 4.1.7.2. The dipped beams may remain switched on at the same time as the main beams. 4.1.7.3. Where four concealable main-beam headlamps are fitted their raised position must prevent the  simultaneous operation of any additional main-beam headlamps fitted, if these are intended to  provide light signals (as defined in item 3.13) in daylight. 4.1.8.

Height: above the ground: not less than 500 mm and not more than 1 200 mm. 4.2.4.3. Length: at the front of the vehicle; this requirement shall be regarded as satisfied if the light emitted  does not cause discomfort to the driver either directly, or indirectly through the rear-view  mirrors and/or other reflecting surfaces of the vehicle. 4.2.5. Geometric visibilityDefined by angles á and â as specified in item 1.13. á = 15o upwards and 10o downwards, â = 45o outwards and 10o inwards. Since the photometric values required for dipped-beam headlamps do not cover the full geometric  field of vision, a minimum value of 1 cd in the space remaining is required for type-approval  purposes. The presence of panels or other items of equipment near the light must not give rise to  secondary effects causing discomfort to other road users. 4.2.6. Alignment4.2.6.1. After adjustment of the initial inclination, the vertical inclination of the dipped beam, expressed  in percent, shall be measured in static conditions under all the loading conditions defined in  Appendix 1.The initial downward inclination of the cut-off of the dipped beam to be set in the unladen vehicle  state with one person in the driver's seat shall be specified to within 0,1 % by the vehicle  manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to  either headlamps or the manufacturer's plate by the symbol shown in Appendix 6. The value of this indicated downward inclination is defined in item 4.2.6.1.1. 4.2.6.1.1. Depending on the mounting height in meters (h) of the lower edge of the illuminating surface of the  dipped-beam headlamp, measured on the unladen vehicle, the vertical inclination of the cut-off of  the dipped beam shall, under all the static conditions of Appendix 1, remain between the following  limits and the initial aiming shall have the following values: h <  0,80limits: between  0,5 % and  2,5 %initial aiming: between  1,0 % and  1,5 %; 0,80 § h § 0,90limits: between  0,5 % and  2,5 %initial aiming: between  1,0 % and  1,5 %,or, at the discretion of the vehicle manufacturerlimits: between  1,0 % and  3,0 %initial aiming: between  1,5 % and  2,0 %; the application for EC vehicle type-approval shall, in this case, contain information as to which  of the two alternatives is to be used; h > 0,90limits: between  1,0 % and  3,0 %initial aiming: between  1,5 % and  2,0 %. The above limits and the initial aiming values are summarized in the diagram below. 4.2.6.2. The preceding condition may be satisfied by means of a device acting on the relative position of  the headlamp and the vehicle. In the case of this device failing the beam must not return to a  position less inclined downwards than its position at the time of failure of the device. 4.2.6.2.1. The device mentioned in item 4.2.6.2 must be automatic. 4.2.6.2.2. Devices which are adjusted manually, either continuously or non-continuously, shall nevertheless be  permitted, provided they have a stop position at which the lamps can be returned to the initial  inclination defined in item 4.2.6.1 by means of the usual adjusting screws. These manually  adjustable devices must be operable from the driving seat. Continually adjustable devices must have  reference marks indicating the loading conditions that require adjustment of the dipped beam. The number of positions on devices which are not continuously adjustable must be such as to ensure  compliance with the range of values specified in item 4.2.6.1.1 in all the loading conditions  defined in Appendix 1. For these devices also, the loading conditions of Appendix 1 that require adjustment of the dipped  beam shall be clearly marked near the control of the device (see Appendix 7). 4.2.6.2.3. The measurement of the variation of dipped-beam inclination as a function of load must be carried  out in accordance with the test procedure set out in Appendix 5. 4.2.7.

SCOPEThis Appendix specifies a method for measuring variations in motor vehicle dipped beam  inclination, in relation to its initial inclination, caused by changes in vehicle attitude due to  loading. 2. DEFINITIONS2.1. Initial inclination2.1.1. Stated initial inclination: the value of the dipped beam initial inclination specified by the motor vehicle manufacturer  serving as a reference value for the calculation of permissible variations. 2.1.2. Measured initial inclination: the mean value of dipped beam inclination or vehicle inclination measured with the vehicle in  condition N° 1, as defined in Appendix 1, for the category of vehicle under test. It serves as a  reference value for the assessment of variations in beam inclination as the load varies. 2.2. Dipped-beam inclinationIt may be defined as follows: - either as the angle, expressed in milliradians, between the direction of the beam towards a  characteristic point on the horizontal part of the cut-off in the luminous distribution of the  headlamp and the horizontal plane, - or by the tangent of that angle, expressed in percentage inclination, since the angles are small  (for these small angles, 1 % is equal to 10 mrad). If the inclination is expressed in percentage inclination, it can be calculated by means of the  following formula:   h1 h2  × 100  h1 h2l× 100where: h1 is the height above the ground, in millimetres, of the abovementioned characteristic point,  measured on a vertical screen perpendicular to the vehicle longitudinal median plane, placed at a  horizontal distance I; h2 is the height above the ground, in millimetres, of the centre of reference (which is taken to be  the nominal origin of the characteristic point chosen in h1); lis the distance, in millimetres, from the screen to the centre of reference. Negative values denote downward inclination (see Figure 1). Positive values denote upward inclination. >START OF GRAPHIC><?aa8H>Figure 1>END OF GRAPHIC>Notes: 1.  This drawing represents a category M1 vehicle, but the principle shown applies equally to  vehicles of other categories. 2.  Where the vehicle does not incorporate a headlamp levelling system, the variation in dipped  beam inclination is identical with the variation in the inclination of the vehicle itself. 3. MEASUREMENT CONDITIONS3.1. If a visual inspection of the dipped beam pattern on the screen or a photometric method is used,  measurement shall be carried out in a dark environment (for example, a dark room) of sufficient  area to allow the vehicle and the screen to be placed as shown in Figure 1. Headlamp centres of  reference shall be at a distance I from the screen of at least 10 m. 3.2. The ground on which measurements are made shall be as flat and horizontal as possible, so that the  reproducibility of measurement of dipped beam inclination can be assured with an accuracy of p 0,5  mrad (p 0,05 % inclination). 3.3. If a screen is used, its marking, position and orientation in relation to the ground and to the  median longitudinal plane of the vehicle, shall be such that the reproducibility of the measurement  of the dipped beam inclination can be assured with an accuracy of p 0,5 mrad (p 0,05 %  inclination). 3.4. During measurements, the ambient temperature shall be between 10 and 30o C. 4. VEHICLE PREPARATION4.1.Measurements shall be carried out on a vehicle which has travelled a distance of between 1 000 and  10 000 km, preferably 5 000 km. 4.2. Tyres shall be inflated to the full-load pressure specified by the vehicle manufacturer. The  vehicle shall be fully replenished (fuel, water, oil) and equipped with all the accessories and  tools specified by the manufacturer. Full fuel replenishment means that the fuel tank must be  filled to not less than 90 % of its capacity as indicated in the information document, a model of  which appears in Annex I to Directive 70/156/EEC. 4.3. The vehicle shall have the parking brake released and the gearbox in neutral. 4.4. The vehicle shall be conditioned for at least eight hours at the temperature specified in item  3.4. 4.5. If a photometric or visual method is used, headlamps with a well-defined dipped beam cut-off should  preferably be installed on the vehicle under test in order to facilitate the measurements. Other means are allowed to obtain a more precise reading (for example, removal of the headlamp  lens). 5. TEST PROCEDURE5.1. GeneralThe variations in either dipped beam or vehicle inclination, depending on the method  chosen, shall be measured separately for each side of the vehicle. The results obtained from both  left and right headlamps under all the load conditions specified in Appendix 1, shall be within the  limits set out in item 5.5. The load shall be applied gradually without subjecting the vehicle to  excessive shocks. 5.2. Determination of the measured initial inclinationThe vehicle shall be prepared as specified in  item 4 and laden as specified in Appendix 1 (first loading condition of the respective vehicle  category). Before each measurement, the vehicle shall be rocked as specified in item 5.4. Measurement shall be made three times. 5.2.1. If none of the three measured results differs by more than 2 mrad (0,2 % inclination) from the  arithmetic mean of the results, that mean shall constitute the final result. 5.2.2. If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 %  inclination), a further series of 10 measurements shall be made, the arithmetic mean of which shall  constitute the final result. 5.3. Measurement methodsAny method may be used to measure variations of inclination provided that the  readings are accurate to within p 0,2 mrad (p 0,02 % inclination). 5.4. Treatment of vehicle in each loading conditionThe vehicle suspension and any other part likely to  affect dipped beam inclination shall be activated according to the methods described below. However, the technical authorities and manufacturers may jointly propose other methods (either  experimental or based upon calculations), especially when the test poses particular problems,  provided such calculations are clearly valid. 5.4.1. M1 category vehicles with conventional suspensionWith the vehicle standing on the measuring site  and, if necessary, with the wheels resting on floating platforms (which must be used if their  absence would lead to restriction of the suspension movement likely to affect the results of  measurements), rock the vehicle continuously for at least three complete cycles; for each cycle,  first the rear and then the front end of the vehicle is pushed down. The rocking sequence shall end with the completion of a cycle. Before making the measurements, the  vehicle shall be allowed to come to rest spontaneously. Instead of using floating platforms, the same effect can be achieved by moving the vehicle  backwards and forwards for at least a complete wheel revolution. 5.4.2. M2, M3 and N category vehicles with conventional suspension5.4.2.1. If the treatment method for cateogory M1 vehicles described in item 5.4.1 is not possible, the  method described in item 5.4.2.2 or 5.4.2.3 may be used. 5.4.2.2. With the vehicle standing on the measuring site and the wheels on the ground, rock the vehicle by  temporarily varying the load. 5.4.2.3. With the vehicle standing on the measuring site and the wheels on the ground, activate the vehicle  suspension and all other parts which may affect the dipped beam inclination by using a vibration  rig. This can be a vibrating platform on which the wheels rest. 5.4.3. Vehicles with non-conventional suspension, where the engine has to be runningBefore making any  measurement wait until the vehicle has assumed its final attitude with the engine running. 5.5. MeasurementsThe variation of the inclination of the dipped beam shall be assessed for each of the  different loading conditions in relation to the measured initial inclination determined in  accordance with item 5.2. If the vehicle is fitted with a manual headlamp-levelling system, the latter shall be adjusted to  the positions specified by the manufacturer for given loading conditions (according to Appendix  1). 5.5.1. To begin with, a single measurement shall be made in each loading condition. Requirements have been  met if, for all the loading conditions, the variation in inclination is within the calculated  limits (for example, within the difference between the stated initial inclination and the lower and  upper limits specified for approval) with a safety margin of 4 mrad (0,4 % inclination). 5.5.2. If the result(s) of any measurement(s) does (do) not lie within the safety margin indicated in item  5.5.1 or exceed(s) the limit values, a further three measurements shall be made in the loading  conditions corresponding to this (these) result(s) as specified in item 5.5.3. 5.5.3. For each of the above loading conditions: 5.5.3.1. If none of the three measured results differs by more than 2 mrad (0,2 % inclination), from the  arithmetic mean of the results, that mean shall constitute the final result. 5.5.3.2. If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 %  inclination), a further series of 10 measurements shall be made, the arithmetic mean of which shall  constitute the final result. 5.5.3.3. If a vehicle is fitted with an automatic headlamp-levelling system which has an inherent hysteresis  loop, average results at the top and bottom of the hysteresis loop shall be taken as significant  values. All these measurements shall be made in accordance with items 5.5.3.1 and 5.5.3.2. 5.5.4. Requirements have been met, if, under all loading conditions, the variation between the measured  initial inclination determined in accordance with item 5.2 and the inclination measured under each  loading condition is less than the values calculated in item 5.5.1 (without safety margin). 5.5.5. If only one of the calculated upper or lower limits of variation is exceeded, the manufacturer  shall be permitted to chose a different value for the stated initial inclination, within the limits  specified for approval.

Appendix 7 THE CONTROLS FOR THE HEADLAMP-LEVELLING DEVICES REFERRED TO IN ITEMS 4.2.6.2.2 OF ANNEX  I 1. SPECIFICATIONS1.1. Downward inclination of the dipped beam must in all cases be produced in one of the following  ways: (a)  by moving a control downwards or to the left; (b)by rotating a control in a counter-clockwise direction; (c)by depressing a button (push-pull control). If several buttons are used to adjust the beam, the button which gives the greatest downward  inclination must be installed to the left or below the button(s) for other dipped-beam positions. A rotary control which is installed edge-on, or with only the edge visible, should follow the  operating principles of controls of types (a) or (c). 1.1.1. This control must carry symbols indicating clearly the movements corresponding to the downward and  upward inclination of the dipped beam. 1.2. The '0` position corresponds to the initial inclination according to item 4.2.6.1 of Annex I. 1.3. The '0` position which, according to item 4.2.6.2.2 of Annex I, has to be a 'stop position`, need  not necessarily be at the end of the scale. 1.4.
