4. APPROVAL
4.1. General
4.1.1. If all the samples of a type of headlamp submitted pursuant to Paragraph 2 above satisfy the
provisions of this Regulation, approval shall be granted.
4.1.2. Where grouped, combined or reciprocally incorporated lamps satisfy the requirements of
more than one Regulation, a single international approval mark may be affixed provided that
each lamp of the grouped, combined or reciprocally incorporated lamps satisfies the
provisions applicable to it. This requirement shall not apply to headlamps fitted with a
two-filament bulb when a single beam is approved.
4.1.3. An approval number shall be assigned to each type approved. The same Contracting Party
may not assign the same number to another type of headlamp covered by this Regulation
except in the case of an extension of the approval to a device differing only in the colour of
the light emitted.
4.1.4. Notice of approval or of extension or refusal or withdrawal of approval or production definitely
discontinued of a type of headlamp pursuant to this Regulation shall be communicated to the
Parties to the 1958 Agreement applying this Regulation, by means of a form conforming to
the model shown in Annex 1 to this Regulation with the indications according to
Paragraph 2.2.1. and if the headlamp is equipped with an adjustable reflector and if the
headlamp is to be used only in mounting positions according to the indications in
Paragraph 2.2.1., the applicant shall be obliged by the approval to inform the user in a proper
way about the correct mounting position(s)..
4.1.5. In addition to the mark prescribed in Paragraph 3.1, an approval mark as described in
Paragraphs 4.2 and 4.3 below shall be affixed in the spaces referred to in Paragraph 3.2
above to every headlamp conforming to a type approved under this Regulation.

4.2.2.7. In every case the relevant operating mode used during the test procedure according to
Paragraph 1.1.1.1 of Annex 4 and the permitted voltage(s) according to Paragraph 1.1.1.2 of
Annex 4 shall be stipulated on the approval certificate and on the communication form
transmitted to the countries which are Contracting Parties to the Agreement and which apply
this Regulation.
In the corresponding cases the device shall be marked as follows:
On headlamps meeting the requirements of this Regulation which are so designed that the
filament of the passing beam shall not be lit simultaneously with that of any other lighting
function with which it may be reciprocally incorporated: an oblique stroke (/) shall be placed
behind the passing lamp symbol in the approval mark.
On headlamps meeting the requirements of Annex 4 to this Regulation only when supplied
with a voltage of 6 V or 12 V, a symbol consisting of the number 24 crossed out by an oblique
cross (X), shall be placed near the filament lamp holder.
4.2.2.8. The two digits of the approval number which indicate the series of amendments in force at the
time of issue of the approval and, if necessary, the required arrow may be marked close to
the above additional symbols.
4.2.2.9. The marks and symbols referred to in Paragraphs 4.2.1 and 4.2.2 above shall be clearly
legible and be indelible even when the device is fitted in the vehicle.
4.3. Arrangement of the Approval Mark
4.3.1. Independent Lamps
Annex 5, Figures 1 to 9, to this Regulation gives examples of arrangements of the approval
marks with the above-mentioned additional symbols.
4.3.2. Grouped, Combined or Reciprocally Incorporated Lamps
4.3.2.1. Where grouped, combined or reciprocally incorporated lamps have been found to comply with
the requirements of several Regulations, a single international approval mark may be affixed,
consisting of a circle surrounding the Letter "E" followed by the distinguishing number of the
country which has granted the approval, and an approval number. This approval mark may
be located anywhere on the grouped, combined or reciprocally incorporated lamps, provided
that:
4.3.2.1.1. It is visible after their installation;
4.3.2.1.2. No part of the grouped, combined or reciprocally incorporated lamps that transmits light can
be removed without at the same time removing the approval mark.
4.3.2.2. The identification symbol for each lamp appropriate to each Regulation under which approval
has been granted, together with the corresponding series of amendments incorporating the
most recent major technical amendments to the Regulation at the time of issue of the
approval and, if necessary, the required arrow shall be marked:
4.3.2.2.1. Either on the appropriate light-emitting surface,
4.3.2.2.2. Or in a group, in such a way that each of the grouped, combined or reciprocally incorporated
lamps may be clearly identified (see four possible examples in Annex 5).

5.4. The components by which the filament lamp is fixed to the reflector shall be so made that, even
in darkness, the filament lamp can be fixed in no position but the correct one.
The filament lamp-holder shall conform to the dimensional characteristics as given in the
following data sheets of IEC Publication 61-2:
Filament lamp Holder Data sheet
R2
HS1
P45t-41
PX43t
7005-95-1
7005-34-1
5.5. Headlamps designed to satisfy the requirements both of countries in which traffic moves on the
right and of those in which it moves on the left may be adapted for traffic on a given side of the
road either by an appropriate initial adjustment when the vehicle is fitted out or by selective
setting by the driver. Such initial adjustment or selective setting shall consist, for example, of
fixing either the optical unit at a given angle on the vehicle or the filament lamp at a given angle
in relation to the optical unit. In all cases, only two precisely differentiated setting positions, one
for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude
inadvertent shifting of the headlamp from one position to another or its setting in an
intermediate position. Where two different setting positions are provided for the filament lamp,
the components attaching the filament lamp to the reflector must be so designed and
manufactured that, in each of its two settings, the filament lamp will be held in position with the
precision required for head lamps intended for traffic on only one side of the road.
5.6. Complementary tests shall be done according to the requirements of Annex 4 to ensure that in
use there is no excessive change in photometric performance.
5.7. Conformity with the requirements of Paragraphs 5.2 to 5.5 shall be verified visually and, where
necessary, by a test fitting.
5.8. If the lens of the headlamp is of plastic material, tests shall be done according to the
requirements of Annex 7.
6. ILLUMINATION
6.1.1. Headlamps shall be so made that with suitable R2 and/or HS1 filament lamp(s) they provide
adequate illumination without dazzle in the case of passing beam and good illumination in the
case of the driving beam.
6.1.2. The illumination produced by the headlamp shall be checked on a vertical screen set at a
distance of 25 m in front of the headlamp and at right angles to its axis (see Annex 6).

Where a headlamp so adjusted does not meet the requirements referred to in Paragraphs 6.3
and 6.5, its adjustment may be changed, provided that the axis of the beam or the point of
intersection HV specified in Annex 6 to this Regulation is not laterally displaced by more
than 1° (=44 cm) to the right or left. To facilitate adjustment by means of the "cut-off", the
head lamp may be partially occulted in order to sharpen the "cut-off".
If the headlamp is designed solely to provide a driving beam, it shall be so adjusted that the
area of maximum illumination is centred on the point of intersection of the Lines hh and
vv. Such a headlamp need meet only the requirements referred to in Paragraph 6.5.
6.3. The illumination produced on the screen by the passing beam shall meet the requirements of
the following table:
Headlamps for
right-hand traffic
Point B 50 L

It is understood that, where the flux of the standard filament lamp used for measurement is
other than 450 lumens, the measurements as taken will be corrected proportionally to the rates
of the fluxes. There shall be no lateral variations detrimental to good visibility in any of the
Zones I, II, III and IV.
Headlamps designed to meet the requirements of both right-hand and left-hand traffic must, in
each of the two setting positions of the optical unit or of the filament lamp, meet the
requirements set forth above for the corresponding traffic system.

This maximum value shall not be less than 32 lux.
Starting from point of intersection HV, horizontally to the right and left, illumination shall be not
less than 16 lux up to a distance of 1.125 m and not less than 4 lux up to a distance of 2.25 m.
(Where the flux of the standard filament lamp used for measurements is other than
700 lumens, the measurements as taken must be corrected proportionally to the ratio of the
fluxes.)
6.7. The screen illumination values mentioned under Paragraphs 6.3 and 6.6 above shall be
measured by means of a photo-electric cell, the useful area of which shall be contained within a
square of 65 mm side.
7. GAUGING OF DISCOMFORT
The discomfort caused by the passing beam of headlamps shall be gauged.
8. STANDARD HEADLAMP
