Extreme outer edge  "Extreme outer edge" on either side of the tractor means the plane parallel with the median longitudinal plane of the tractor and coinciding with its lateral outer edge, disregarding the projection:        1.10.1. of tyres near their point of contact with the ground and connections for tyre-pressure gauges;               1.10.2. of any anti-skid devices which may be mounted on the wheels;               1.10.3. of rear-view mirrors;               1.10.4. of side direction indicator lamps, end-outline marker lamps, front and rear position (side) lamps and parking lamps,               1.10.5. of customs seals affixed to the tractor and devices for securing and protecting such seals.                          1.11. Overall width  "Overall width" means the distance between the two vertical planes defined in 1.10 above.           1.12. A single lamp  "A single lamp" means any combination of two or more lamps, whether identical or not, having the same function and colour, if it comprises devices, the projection of whose aggregate light-emitting surfaces in a given transverse plane occupies 60 % or more of the area of the smallest rectangle circumscribing the projections of the light-emitting surfaces of the aforementioned lamps, provided that such combination is, where approval is required, approved as a single lamp.  This possible combination does not apply to main-beam headlamps, dipped-beam headlamps and front fog lamps.           1.13. Two lamps or an even number of lamps  "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 tractor and extending on both sides to within not less than 400 mm of the extreme outer edge of the tractor, 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 in 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.           1.14. Distance between two lamps  "Distance between two lamps" which face in the same direction, means the distance between the orthogonal projections in a plane perpendicular to the direction in question of the outlines of the two illuminating surfaces as defined according to the case mentioned in 1.6.           1.15. Optional lamp  "Optional lamp" means a lamp the presence of which is left to the discretion of the manufacturer.           1.16.

The document provided for in Annex II shall be attached to the type-approval document.                  3. GENERAL SPECIFICATIONS      3.1. The lighting and light-signalling devices must be so fitted that under normal conditions of use, and notwithstanding any vibration to which they may be subjected, they retain the characteristics laid down in this Annex and enable the tractor 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.        3.1.1. Tractors must be equipped with electrical connectors to enable a detachable light-signalling system to be used. In particular tractors must be fitted with the permanently connected socket outlet recommended in standard ISO R 1724 (Electrical connections for vehicles with 6 or 12 volt electrical systems applying more specifically to private motor cars and light-weight trailers or caravans) (first edition, April 1970) or ISO R 1185 (Electrical connections between towing and towed vehicles having 24 volt electrical systems used for international commercial transport purposes) (first edition, March 1970). In the case of standard ISO R 1185, the function of contact 2 shall be restricted to the rear position (side) lamp and to the end-outline marker lamp on the left-hand side.                          3.2. The illuminating lamps described in 1.5.7, 1.5.8 and 1.5.9 must be so fitted that a correct setting of their alignment can easily be performed.           3.3. For all light-signalling devices, the reference axis of the lamp when fitted to the tractor must be parallel with the bearing plane of the tractor on the road and with the longitudinal plane of the tractor. In each direction a tolerance of ± 3º shall be allowed. In addition, any specific instructions as regards fitting laid down by the manufacturer must be complied with.           3.4. In the absence of specific instructions, the height and alignment of the lamps shall be checked with the unladen tractor placed on a flat, horizontal surface.           3.5. In the absence of specific requirements, lamps constituting a pair shall:        3.5.1. be fitted to the tractor symmetrically in relation to the median longitudinal plane;               3.5.2. be symmetrical to one another in relation to the median longitudinal plane;               3.5.3. satisfy the same colorimetric characteristics;               3.5.4. have substantially identical photometric characteristics.                          3.6. On tractors whose external shape is asymmetrical, the requirements of 3.5.1 and 3.5.2 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           3.7. 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.           3.8. The maximum height above ground shall be measured from the highest point and the minimum height from the lowest point of the illuminating surface.            3.9. In the absence of specific requirements no lamps other than direction indicator lamps and the hazard warning signal may emit a flashing light.           3.10. 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:        3.10.1. for the visibility of a red light towards the front : there is no direct visibility of a red light if viewed by an observer moving within zone 1 in a transverse plane situated 25 m in front of the tractor (see Appendix 2, Figure 1);               3.10.2. for the visibility of a white light towards the rear : there is no direct visibility of a white light if viewed by an observer moving within zone 2 in a transverse plane situated 25 m behind the tractor (see Appendix 2, Figure 2).               3.10.3. Zones 1 and 2, as seen by the observer, are limited in their respective planes as follows:          3.10.3.1. as regards height, by two horizontal planes which are 1 m and 2 72 m respectively above the ground;                   3.10.3.2. as regards width, by two vertical planes which make an angle of 15º 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.                                             3.11. 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.           3.12. The electrical connections must be such that the main-beam and dipped-beam headlamps, and the front and rear fog lamps cannot be switched on unless the lamps referred to in 3.11 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 dipped-beam headlamps or the intermittent lighting up of the main-beam headlamps or the alternate lighting up at short intervals of the dipped-beam and main-beam headlamps.           3.13. The colours of the light emitted by the lamps or reflectors are as follows:        - main-beam headlamp : white or selective yellow,               - dipped-beam headlamp : white or selective yellow,               - 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 (side) lamp : white ; selective yellow is permitted if the front position (side) lamp is a selective yellow headlamp,               - rear position (side) lamp : red,               - rear fog-lamp : red,               - parking lamp : white in front, red at the rear, amber if incorporated in the side direction indicator lamps,               - work lamp : no specifications,               - end-outline marker lamp : white in front, red at the rear,               - rear reflex reflector, non-triangular : red.                 However, as long as all the requirements necessary for obtaining EEC vehicle type-approval do not apply, the choice of the colour of the light emitted by main-beam and dipped-beam headlamps and front fog-lamps shall be left to the Member States           3.14. The function of the circuit-closed tell-tales may be fulfilled by operational tell-tales.           3.15. Concealable lamps        3.15.1. The concealment of lamps shall be prohibited, with the exception of main-beam headlamps, dipped-beam headlamps and front fog-lamps, which may be concealed when not in use.                3.15.2. An illuminating device in the position of use shall remain in that position if the malfunction referred to in 3.15.2.1 occurs alone or in conjunction with one of the malfunctions described in 3.15.2.2.          3.15.2.1. The absence of power for manipulating the lamp.                   3.15.2.2. A break, impedance, or short-circuit to earth in the electrical circuit, defects in the hydraulic or pneumatic leads, Bowden cables, solenoids or other components controlling or transmitting the energy intended to activate the concealment device.                                  3.15.3. In the event of a defect in the concealment control, a concealed lighting device shall be capable of being moved into the position of use without the aid of tools.               3.15.4. It must be possible to move illuminating devices 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.               3.15.5. 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.               3.15.6.
