2.1. ‘Vehicle type’ means a category of vehicles which do not differ from each other in such essential respects as:

2.1.1. The dimensions and external shape of the vehicle;

2.1.2. The number and position of the devices;

2.1.3. The following shall likewise not be deemed to be ‘vehicles of a different type’:

2.1.3.1. Vehicles which differ within the meaning of paragraphs 2.1.1 and 2.1.2 above but not in such a way as to entail a change in the kind, number, position and geometric visibility of the lamps prescribed for the vehicle type in question; and

2.1.3.2. Vehicles on which lamps approved under one of the Regulations annexed to the 1958 Agreement, or lamps allowed in the country in which the vehicles are registered, are fitted, or are absent where their fitting is optional;

2.2. ‘Unladen vehicle’ means a vehicle without a driver, or passenger, and unladen, but with its fuel tank full and its normal complement of tools;

2.3. ‘Lamp’ means a device designed to illuminate the road or to emit a light signal to other road users. Rear registration plate lamp and retro-reflectors are likewise to be regarded as lamps;

2.3.1. ‘Equivalent lamps’ means lamps having the same function and authorised in the country in which the vehicle is registered; such lamps may have different characteristics from those of the lamps with which the vehicle is equipped at the time of approval, on condition that they satisfy the requirements of this Regulation;

2.3.2. ‘Independent lamp’ means devices having separate apparent surfaces, separate light sources and separate lamp bodies;

2.3.3. ‘Grouped lamps’ means devices having separate apparent surfaces and separate light sources, but a common lamp body;

2.3.4. ‘Combined lamps’ means devices having separate apparent surfaces, but a common light source and a common lamp body;

2.3.5. ‘Reciprocally incorporated’ means devices having separate light sources or a single light source operating under different conditions (for example, optical, mechanical, electrical differences), totally or partially common apparent surfaces and a common lamp body;

2.3.6. ‘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;

A direction indicator lamp or lamps may also be used according to provisions of UN Regulation No 97.

2.3.7. ‘Front position lamp’ means the lamp used to indicate the presence of the vehicle when viewed from the front;

2.3.8. ‘Rear position lamp’ means the lamp used to indicate the presence of the vehicle when viewed from the rear;

If the lighting device has no reflector, the definition of paragraph 2.5.2 below shall be applied. If the light emitting surface of the lamp extends 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-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;

To determine the lower, upper and lateral limits of the illuminating surface, only screens with horizontal or vertical edges shall be used;

2.5.3. ‘Illuminating surface of a retro-reflector’ (para. 2.3.9 above) means the orthogonal projection of a retro-reflector in a plane perpendicular to its axis of reference and delimited by planes continuous to the outermost parts of the retro-reflector’s optical system and parallel to that axis. For the purposes of determining the lower, upper and lateral edges of the device, only horizontal and vertical planes shall be considered;

2.6. The ‘apparent surface’ for a defined direction of observation means, at the request of the manufacturer or his duly accredited representative, the orthogonal projection of:

Either the boundary of the illuminating surface projected on the exterior surface of the lens (a-b),

Or the light-emitting surface (c-d),

In a plane perpendicular to the direction of observation and tangential to the most exterior point of the lens (see Annex 3 to this Regulation);

2.7. ‘Centre of reference’ means the intersection of the axis of reference with the exterior light-emitting surface; it is specified by the manufacturer of the lamp;

2.8. ‘Extreme outer edge’, on either side of the vehicle means the plane parallel to the median longitudinal plane of the vehicle and touching the lateral extremity of the vehicle, disregarding the projection or projections:

2.8.1. Of rear-view mirrors,

2.8.2. Of direction indicator lamps,

2.8.3. Of front and rear position lamps and retro-reflectors;

2.12. ‘Laden’ means so loaded as to attain the gross vehicle mass as defined in paragraph 2.11 above.

2.13. ‘Horizontal inclination’ means the angle created between the beam pattern when the motorcycle is set as specified in paragraph 5.4 of this Regulation, and the beam pattern when the motorcycle is banked (see drawing in Annex 6);

2.14. ‘Horizontal inclination adjustment system (HIAS)’ means a device that adjusts the horizontal inclination of the headlamp towards zero;

2.15. ‘Bank angle’ means the angle made with the vertical by the vertical longitudinal median plane of the motorcycle, when the motorcycle is rotated about its longitudinal axis (see drawing in Annex 6);

2.16. ‘HIAS signal’ means any control signal or, any additional control input to the system or, a control output from the system to the motorcycle;

2.17. ‘HIAS signal generator’ means a device, reproducing one or more of the HIAS signals for system test;

2.18. ‘HIAS test angle’ means the angle δ created by the headlamp cut-off line and HH line (in case of an asymmetrical beam headlamp, the horizontal part of the cut-off shall be used), (see drawing in Annex 6).

2.19. ‘Bend lighting’ means a lighting function to provide enhanced illumination in bends.

2.20. ‘H plane’ means the horizontal plane containing the centre of reference of the lamp.

2.21. ‘Sequential activation’ means an electrical connection where the individual light sources of a lamp are wired such that they are activated in a predetermined sequence.

2.22. ‘Emergency stop signal’ means a signal to indicate to other road users to the rear of the vehicle that a high retardation force has been applied to the vehicle relative to the prevailing road conditions.

5.6.1. Lamps may be grouped, combined or reciprocally incorporated with one another provided that all requirements regarding colour, position, orientation, geometric visibility, electrical connections and other requirements, if any, are fulfilled.

5.6.1.1. The photometric and colorimetric requirements of a lamp shall be fulfilled when all other functions with which this lamp is grouped, combined or reciprocally incorporated are switched OFF.

However, when a front or rear position lamp is reciprocally incorporated with one or more other function(s) which can be activated together with them, the requirements regarding colour of each of these other functions shall be fulfilled when the reciprocally incorporated function(s) and the front or rear position lamps are switched ON.

5.6.1.2. Stop lamps and direction indicator lamps are not permitted to be reciprocally incorporated.

5.6.1.3. However, where stop lamps and direction indicator lamps are grouped, any horizontal or vertical straight line passing through the projections of the apparent surfaces of these functions on a plane perpendicular to the reference axis, shall not intersect more than two borderlines separating adjacent areas of different colour.

5.6.2. Single lamps

5.6.2.1. Single lamps as defined in paragraph 2.16.1 of UN Regulation No 48, subparagraph (a), composed of two or more distinct parts, shall be installed in such a way that:

(a) Either the total area of the projection of the distinct parts on a plane tangent to the exterior surface of the outer lens and perpendicular to the reference axis shall occupy not less than 60 per cent of the smallest quadrilateral circumscribing the said projection; or

(b) The minimum distance between the facing edges of two adjacent/tangential distinct parts shall not exceed 75 mm when measured perpendicularly to the reference axis.

These requirements shall not apply to a single retro-reflector.

5.6.2.3. Single lamps as defined in paragraph 2.16.1 of UN Regulation No 48, subparagraph (d), shall fulfil the requirements of paragraph 5.6.2.1.

Where two or more lamps and/or two or more separate apparent surfaces are included into the same lamp body and/or have a common outer lens, these shall not be considered as an interdependent lamp system.

However, a lamp in the shape of a band or strip may be part of an interdependent lamp system.

5.7. The maximum height above ground shall be measured from the highest point and the minimum height from the lowest point of the apparent surface in the direction of the reference axis. For passing-beam headlamps, the minimum height from the ground shall be measured from the lowest point of the effective outlet of the optical system (e.g. reflector, lens, projection lens) independent of its utilisation.

Where the (maximum and minimum) height above the ground clearly meets the 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.

For the purposes of reducing the geometric visibility angles, the position of a lamp with regard to height above the ground, shall be measured from the H plane.

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

5.8.1. The photometric characteristics of a direction indicator lamp except for categories 5 and 6 specified in UN Regulation No 6 or UN Regulation No 148, and of a direction indicator lamp specified in UN Regulation No 50 or UN Regulation No 148 may be varied during a flash by sequential activation of light sources as specified in paragraph 5.6 of UN Regulation No 6 or paragraph 5.6.11 of UN Regulation No 148 or in paragraph 6.8 of UN Regulation No 50.

This provision shall not apply when direction indicator lamps of categories 2a and 2b of UN Regulation No 6 or UN Regulation No 148 or category 12 of UN Regulation No 50 or UN Regulation No 148 are operated as emergency stop signal according to paragraph 6.14 of this Regulation.

No red light which could give rise to confusion shall be emitted from a lamp as defined in paragraph 2.5 in a forward direction and no white light which could give rise to confusion, shall be emitted from a lamp as defined in paragraph 2.5 in a rearward direction. No account shall be taken of lighting devices fitted for the interior lighting of the vehicle. In case of doubt, this requirement shall be verified as follows (see drawing in Annex 4):

5.9.1. Visibility of red light towards the front: a red lamp shall 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 shall 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° 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, unless otherwise specified.

5.10.1. In the case of an interdependent lamp system, all light sources shall be switched on and off 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 alternately at short intervals.

5.11.1. If installed, the daytime running lamp shall automatically be ON when the engine is running. If the headlamp is switched on, the daytime running lamp shall not come on when the engine is running.

5.20.1. There shall 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. However, no account is taken of obstacles, if they were already present when the lamp was type-approved.

5.20.2. If measurements are taken closer to the lamp, the direction of observation shall be shifted parallel to achieve the same accuracy.

5.20.3. 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.

5.20.4. When the vertical angle of geometric visibility below the horizontal may be reduced to 5 degrees (lamp at less than 750 mm above the ground, measured according to the provisions of paragraph 5.7) the photometric field of measurements of the installed optical unit may be reduced to 5 degrees below the horizontal.
