1.	SCOPE

This Regulation applies to the approval of two-wheeled power-driven vehicles without side-car, having a maximum design speed not exceeding 50 km/h and/or a cylinder capacity not exceeding 50 cm3 or equivalent performance. 1/ 2/

2.	DEFINITIONS

For the purpose of this Regulation,

2.1.	"Approval of a vehicle" means the approval of a vehicle type with regard to the number and mode of installation of the lighting and light-signalling devices;

2.2.	"Vehicle type" means a category of power-driven vehicles which do not differ from each other in such essential respects as:

2.2.1.	the dimensions and external shape of the vehicle;

2.2.2.	the number and position of the devices;

2.2.3.	the following shall likewise not be deemed to be "vehicles of a different type":

2.2.3.1.	vehicles which differ within the meaning of paragraphs 2.2.1. and 2.2.2. 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;

2.2.3.2.	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;

2.3.	"transverse plane" means a vertical plane perpendicular to the median longitudinal plane of the vehicle;

2.4.	"unladen vehicle" means a vehicle without a driver, or passenger, and unladen, but with its fuel tank full and its normal complement of tools;

2.5.	"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;

2.5.1.	"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;

2.5.2.	"Independent lamps" means devices having separate illuminating surfaces, separate light sources and separate lamp bodies;

2.5.3.	"Grouped lamps" means devices having separate illuminating surfaces and separate light sources, but a common lamp body;

2.5.4.	"Combined" means devices having separate illuminating surfaces, but a common light source and a common lamp body;

2.5.5.	"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 illuminating surfaces and a common lamp body;

2.5.6.	"Driving beam (main-beam) headlamp" means the lamp used to illuminate the road over a long distance ahead of the vehicle;

2.5.7.	"Passing beam (dipped-beam) headlamp" means the lamp used to illuminate the road ahead of the vehicle without dazzling of causing undue discomfort to oncoming drivers and other road users;

2.5.8.	"Front position lamp" means the lamp used to indicate the presence of the vehicle when viewed from the front;

2.5.9.	"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 purpose of this Regulation, retro-reflecting number plates are not considered as retro-reflectors:

2.5.10.	"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 Regulation No. 97.

2.5.11.	"Stop lamp" means the lamp used to indicate to other road-users to the rear of the vehicle that its driver is applying the service brake;

2.5.12.	"Rear position lamp" means the lamp used to indicate the presence of the vehicle when viewed from the rear;

2.5.13.	"Rear-registration-plate illuminating device" means the device used to illuminate the space reserved for the rear registration plate; such a device may consist of several optical component.

2.6.	"Light-emitting surface" of a "lighting device", "light-signalling device" or a retro-reflector means all or part of the exterior surface of the transparent material as declared in the request for approval by the manufacturer of the device on the drawing, see annex 3;

2.7.	"Illuminating surface" (see annex 3);

2.7.1.	"Illuminating surface of a lighting device" (paragraphs 2.5.6. and 2.5.7.) means the orthogonal projection of the full aperture of the reflector, or in the case of headlamps with an ellipsoidal reflector of the "projection lens", on a transverse plane. If the lighting device has no reflector, the definition of paragraph 2.7.2. 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;

2.7.2.	"Illuminating surface of a light-signalling device other than a retro-reflector" (paragraphs 2.5.8., 2.5.10., 2.5.11. and 2.5.12.) 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 per cent 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;

2.7.3.	"Illuminating surface of a retro-reflector" (para. 2.5.9.) 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;

2.8.	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);

2.9.	"Axis of reference" (or "reference axis") means the characteristic axis of the lamp determined by the manufacturer (of the lamp) for use as the direction of reference (H = 0°, V = 0°) for angles of field for photometric measurements and for installing the lamp on the vehicle;

2.10.	"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;

2.11.	"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 , correspond to the longitude and the vertical angles 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 annex 3 of this Regulation). Nevertheless, when the vertical angle of geometric visibility below the horizontal may be reduced to 5° (lamp at less than 750 mm above the ground) the photometric field of measurements of the installed optical unit may be reduced to 5° below the horizontal.

2.12.	"Extreme outer edge", on either side of the vehicle means the plane parallel to the median longitudinal plane of the vehicle and tangent to the latter's lateral outer edge, disregarding rear-view mirrors, direction indicators, position lamps and retro-reflectors;

2.13.	"Over-all width" means the distance between the two vertical planes defined in paragraph 2.12. above;

2.14.	"A single lamp" means a device or part of a device, having one function and one apparent surface in the direction of the reference axis (see paragraph 2.8. of this Regulation) 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 so that the projection of their apparent surfaces in the direction of the reference axis occupies not less than 60 per cent of the smallest rectangle circumscribing the projections of the said apparent surfaces in the direction of the reference axis. 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 driving beam headlamps and passing beam headlamps.

2.15.	"Distance between two lamps" which face in the same direction means the shortest distance between the two apparent surfaces in the direction of the reference axis. Where the distance between the lamps clearly meets the requirements of the Regulation, the exact edges of apparent surfaces need not be determined;

2.16.	"Operating tell-tale" means a visual or auditory signal (or any equivalent signal) indicating that a device has been switched on and whether or not it is operating correctly;

2.17.	"Circuit-closed tell-tale" means a visual (or any equivalent signal) indicating that a device has been switched on, but not indicating whether or not it is operating correctly;

2.18.	"Optional lamp" means a lamp, the installation of which is left to the discretion of the manufacturer;

2.19.	"Ground" means the surface on which the vehicle stands which should be substantially horizontal;

2.20.	"Device" means a component or combination of components used in order to perform one or several functions.

3.	APPLICATION FOR APPROVAL

A tolerance of ± 3° shall be allowed in each direction.

In addition, if specifications for fitting are provided by the manufacturer they shall be complied with.

5.4.	In the absence of specific instructions, the height and orientation of the lamps shall be verified with the vehicle unladen and placed on a flat horizontal surface, its median longitudinal plane being vertical and the handlebars being in the position corresponding to the straight ahead movement.

5.5.	In the absence of specific instructions:

5.5.1.	single lamps or reflectors shall be mounted such that their centre of reference lies in the median longitunal plane of the vehicle;

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.

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):

5.10.	The electrical connections shall be such that the front position lamp, or the passing beam headlamp, if there is no front position lamp, and the rear position lamp and any 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 and the passing beam headlamp 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 passing beam headlamp and driving beam headlamp alternately at short intervals.

5.12.	Tell-tale lamps
