This Regulation applies to the approval of headlamps using filament lamps, producing one single passing beam, which are provided for the equipment of mopeds[1/] and vehicles treated as such.
2. DEFINITION OF "TYPE"
Headlamps of different "types" means headlamps which differ in such essential respects as:
2.1. the trade name or mark;
2.2. the characteristics of the optical system;
2.3. the inclusion or the suppression of components capable of altering the optical effects by reflection, refraction or absorption. A change in the colour of the beams emitted by headlamps whose other characteristics are not changed does not constitute a change of headlamp type: The same approval number shall accordingly be assigned to such headlamps.
3. APPLICATION FOR APPROVAL
The application for approval shall be submitted by the holder of the trade name or mark or by his duly accredited representative. Any application shall be accompanied by:
3.1. Drawings in triplicate, sufficiently detailed to permit identification of the type. The drawings must show the provided position for the approval mark and indicate the headlamp in front and in cross lateral elevation, with schematic indication of the optical grooves and prisms of the lens;
3.2. A brief technical description stating, in particular, the class of the filament lamp provided;
3.4. The competent authority shall verify the existence of satisfactory arrangements for ensuring effective control of the conformity of production before type approval is granted.
MARKINGS
4.1. Headlamps submitted for approval shall clearly, legibly and indelibly bear the following inscriptions:
4.1.1. the trade name or mark of the applicant;
4.1.2. the identification of the category of the provided filament lamp;
4.2. Moreover, they shall include on the lens and on the main body (the reflector being considered as main body) [3/] a space of sufficient size to accommodate the approval marking; these spaces must be shown on the drawings referred to in paragraph 3.1. above.
APPROVAL
5.1. If the devices submitted in accordance with paragraph 3. above meet the requirements of this Regulation, approval shall be granted.
5.2. An approval number shall be assigned to each type approved. Its first two digits (at present 00 for the Regulation in its original form) shall indicate the series of amendments incorporating the most recent major technical amendment made to the Regulation at the time of issue of the approval. The same Contracting Party may not assign the same number to another type of headlamp.
5.3. Notice of approval or of extension or refusal of approval of a type of headlamp pursuant to this Regulation shall be communicated to the Parties to the 1958 Agreement which apply this Regulation, by means of a form conforming to the model in annex l to this Regulation.
5.4. Every headlamp conforming to a type approved under this Regulation shall bear in the spaces referred to in paragraph 4.2. above, in addition to the marking prescribed in paragraph 4.1.
5.4.1. an international approval mark [4/] consisting of:
5.4.1.1. a circle surrounding the letter "E" followed by the distinguishing number of the country which has granted approval;[5/].
5.4.1.2. an approval number.
5.5. The markings according to paragraph 5.4. shall be clearly legible and indelible.
5.6. Annex 2 to this Regulation gives an example of the arrangement of the approval mark.
GENERAL SPECIFICATIONS
6.1. Each device shall conform to the specifications of paragraph 7. of this Regulation.
6.2. Headlamps shall be so designed and constructed that, in normal use, despite the vibrations to which they may be subjected, their satisfactory operation continues to be ensured and they retain the characteristics prescribed by this Regulation.
6.3. The parts intended for holding the filament lamp in the reflector shall be so made that, even in darkness, the filament lamp can be mounted in no other position than the correct one.
SPECIAL SPECIFICATIONS
7.1. The correct position of the lens in relation to the optical system shall be unequivocally marked and be locked against rotation in service.
7.2. For the measurement of the illumination produced by the headlamp, a measuring screen as described in annex 3 of this Regulation and a standard filament lamp with a smooth and colourless bulb according to the category S3 of Regulation No. 37 shall be used.
The standard filament lamp shall be adjusted to the applicable reference luminous flux according to values prescribed for these lamps in Regulation No. 37.
7.3. The beam shall have a cut-off sufficiently sharp in order that satisfactory aiming can practically be achieved with its aid. The cut-off shall be substantially horizontal and as straight as possible over a horizontal length of at least +/- 900 mm measured at a distance of 10 m.
When aimed according to annex 3, the headlamps shall meet the requirements specified in it.
7.4. The beam pattern shall not present any lateral variations detrimental to good visibility.
7.5. The illumination on the screen mentioned in paragraph 7.2. above shall be measured by means of a photo-receptor having a useful area comprised within a square of 65 mm side.
PROVISIONS CONCERNING COLOURED LENSES AND FILTERS
8.1. Approval may be obtained for headlamps emitting either colourless or selective-yellow lights with an uncoloured lamp. Expressed in CIE trichromatic co-ordinates, the corresponding colorimetric characteristics for yellow glasses or filters are as follows:
Selective-yellow filter (screen or lens)
Limit towards red y ≥ 0.138 + 0.58 x
Limit towards green y ≤ 1.29 x -0.1
Limit towards white y ≤ - x + 0.966
Limit towards spectral value y ≤- x + 0.992
which can also be expressed as follows:
dominant wave-length 575 - 585 n m

The transmission factor must be ≥ 0.78
The transmission factor shall be determined by using a light source with a colour temperature of 2,854 degrees K. (Corresponding to illuminant A of the International
Commission on Illumination (CIE)) .
8.2. The filter must be part of the headlamp, and must be attached to it in such a way that the user cannot remove it either inadvertently or intentionally, with ordinary tools.
8.3. Observation concerning colour
Since any approval under this Regulation is granted, pursuant to paragraph 8.l. above, for a type of headlamp emitting either colourless light or selective-yellow light; article 3 of the Agreement to which the Regulation is annexed shall not prevent the Contracting Parties from prohibiting headlamps emitting a beam of uncoloured or selective-yellow light on vehicles registered by them.

MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES
GENERAL
1.1. The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation.
1.2. With respect to photometric performances, the conformity of mass-produced headlamps shall not be contested if, when testing photometric performances of any headlamp chosen at random and equipped with a standard filament lamp, no measured value deviates unfavourably by more than 20 % from the values prescribed in this Regulation.
1.3. If the results of the tests described above do not meet the requirements, tests on the headlamp shall be repeated, using another standard filament lamp.
1.4. Headlamps with apparent defects are disregarded.
1.5. The chromaticity coordinates shall be complied with when the headlamp is equipped with a filament lamp set to Standard A colour temperature.
The photometric performance of a headlamp emitting selective yellow light when equipped with a colourless filament lamp shall be the values contained in this Regulation multiplied by 0.84.
MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER
For each type of headlamp the holder of the approval mark shall carry out at least the following tests, at appropriate intervals. The tests shall be carried out in accordance with the provisions of this Regulation. If any sampling shows non-conformity with regard to the type of test concerned, further samples shall be taken and tested. The manufacturer shall take steps to ensure the conformity of the production concerned.
2.1. Nature of tests
Tests of conformity in this Regulation shall cover the photometric characteristics.
2.2. Methods used in tests
2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation.
2.2.2. In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation.
2.2.3. The application of paragraphs 2.2.1. and 2.2.2. requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.
2.2.4. In all cases, the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling.
2.3. Nature of sampling
Samples of headlamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of headlamps of the same type, defined according to the production methods of the manufacturer. The assessment shall in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management.
2.4. Measured and recorded photometric characteristics
The sampled headlamp shall be subjected to photometric measurements at the points provided for in the Regulation, the readings being limited to points HV, LH, RH, L 600 and R 600.
2.5. Criteria governing acceptability
The manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the competent authority, criteria governing the acceptability of his products, in order to meet the specifications laid down for the verification of conformity of products in paragraph 9.1. of this Regulation. The criteria governing the acceptability shall be such that, with a confidence level of 95 %, the minimum probability of passing a spot check in accordance with Annex 5 (first sampling) would be 0.95.
