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

dominant wave-length
575 - 585 n m
purity factor 0,90 - 0,98
The transmission factor must be ≥ 0,78
The transmission factor shall be determined by using a light source with a colour
temperature of 2854 °K. (Corresponding to illuminant A of the International Commission of
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 8.1 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.
9.1. Headlamps approved under this Regulation shall be so manufactured as to conform to the
type-approved by meeting the requirements set forth in Paragraphs 7 and 8.
9.2. In order to verify that the requirements of Paragraphs 9.1. are met, suitable controls of the
production shall be carried out.
9.3. The holder of the approval shall in particular:
9.3.1. Ensure the existence of procedures for the effective control of the quality of products,
9.3.2. Have access to the control equipment necessary for checking the conformity to each
approved type,
9.3.3. Ensure that data of test results are recorded and that related documents shall remain
available for a period to be determined in accordance with the administrative service,
9.3.4. Analyse the results of each type of test in order to verify and ensure the stability of the
product characteristics, making allowance for variation of an industrial production,
9.3.5. Ensure that for each type of product at least the tests prescribed in Annex 4 to this
Regulation are carried out,
9.3.6. Ensure that any collecting of samples giving evidence of non-conformity with the type of test
considered shall give rise to another sampling and another test. All the necessary steps
shall be taken to re-establish the conformity of the corresponding production.
9.4. The competent authority which has granted type-approval may at any time verify the
conformity control methods applicable to each production unit.
9.4.1. In every inspection, the test books and production survey records shall be presented to the
visiting inspector.

If a holder of an approval completely ceases to manufacture a headlamp approved in
accordance with this Regulation, he shall so inform the authority which granted the
approval. Upon receiving the relevant communication that authority shall inform thereof the
other Parties to the 1958 Agreement applying this Regulation by means of a communication
form conforming to the model in Annex 1 to this Regulation.
The Parties to the 1958 Agreement which apply this Regulation shall communicate to the
United Nations Secretariat the names and addresses of the technical services responsible
for conducting approval tests and of the administrative departments which grant approval
and to which forms certifying approval or refusal or withdrawal of approval, issued in other
countries, are to be sent.

on the basis of the 01 series of amendments or the original version of this Regulation,
provided that the headlamps are intended as replacements for fitting to vehicles in use.

14. The attached drawing No. bearing the approval number shows the headlamp ........................

1. For measurements, the measuring screen shall be located at a distance of 10 m in front of
the headlamp and perpendicular to a line joining the filament of the lamp and the point HV;
the line H–H shall be horizontal. For lamps with transverse filament, the filament shall be as
horizontal as possible during the measurements.
2. Laterally, the headlamps shall be so aimed that the beam is as symmetrical as possible with
reference to the line V–V.
3. Vertically, the headlamp shall be so aimed that the illumination in point HV is 2 lx. Under
those conditions, the cut–off shall be situated between the line H–H and the line H–100 mm.
4. When aimed according to Paragraphs 2 and 3 above, the illumination shall meet the
following values:
4.1. on the line H–H and above: 2 lx max :
4.2. on a line situated 300 mm below H–H and over a width of 900 mm in both sides of the
vertical line V–V: not less than 8 lx;
4.3. on a line situated 600 mm below the line H–H and over a width of 900 mm on both sides of
the vertical line V–V: not less than 4 lx.
Measuring Screen
(dimensions in mm for 10 m distance)

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
purposes 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 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.

one headlamp not more than
20 per cent

procedure in Figure 1 of this Annex, the deviations of the measured values of the
headlamps are:
one headlamp not more than
20 per cent
one headlamp more than
30 per cent
A5: both headlamps more than 20 per cent
B4: in the case of A2
one headlamp more than
but not more than

In the cases of A3, B2, B3 a repeated sampling, third sample C of two headlamps and fourth
sample D of two headlamps, selected from stock manufactured after alignment, is
necessary within two months time after the notification.
