5.2.1. Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicles as
to comply with the rules applicable to them. Such a device may or may not provide
horizontal adjustment, provided that the headlamps are so designed that they can maintain
a proper horizontal aiming even after the vertical aiming adjustment. Such a device need not
be fitted on units in which the reflector and the diffusing lens cannot be separated, provided
the use of such units is confined to vehicles on which the headlamp setting can be adjusted
by other means.
Where a headlamp providing a passing beam and a headlamp providing a driving beam,
each equipped with its own filament lamp(s), gas-discharge light source or LED module(s),
are assembled to form a composite unit the adjusting device shall enable each optical
system individually to be duly adjusted.
5.2.2. However, these provisions shall not apply to headlamp assemblies whose reflectors are

apply.
5.3. Class A, B, C or D
5.3.1. Headlamps shall be equipped with filament lamp(s) approved according to Regulation
No. 37 and/or with (an) LED module(s).
In the case of the use of additional light source(s) and/or additional lighting unit(s) to provide
bend lighting, only categories of filament lamps covered by Regulation No. 37, provided that
no restriction on the use for bending light is made in Regulation No. 37 and its series of
amendments in force at the time of application for type approval, and/or LED modules(s)
shall be used.

5.4. Class E Headlamps
5.4.1. The headlamp shall be equipped with (a) gas-discharge light source(s) approved according
to Regulation No. 99 and/or (an) LED module(s).
In the case of the use of additional light source(s) and/or additional lighting unit(s) to provide
bend lighting, only categories of filament lamps covered by Regulation No. 37, provided that
no restriction on the use for bending light is made in Regulation No. 37 and its series of
amendments in force at the time of application for type, and/or LED modules(s) shall be
used.
5.4.2. In the case of replaceable gas-discharge light sources the lamp holder shall conform to the
dimensional characteristics as given on the data sheet of IEC Publication 60061-2, relevant
to the category of gas-discharge light source used. The gas-discharge light source shall fit
easily into the headlamp.
5.4.3. In the case of (an) LED module(s) the following requirements apply:
5.4.3.1. The electronic light source control gear(s), if applicable, shall be considered as being part of
the headlamp; they may also be part of the LED module(s);
5.4.3.2. The headlamp and the LED module(s) themselves shall comply with the relevant
requirements specified in Annex 12 to this Regulation. The compliance with the
requirements shall be tested.
5.4.3.3. The total objective luminous flux of all LED modules producing the principal passing beam
shall be measured as described in Paragraph 5. of Annex 12. The following minimum limit
shall apply:
Principal passing beam
minimum
Headlamps Class E
2,000lm
5.5. In addition, Class B or C or D or E headlamps shall be complementary tested according to
the requirements of Annex 4 to ensure that in use there is not excessive change in
photometric performance.
5.6. If the lens of a Class B or C or D or E headlamp is of plastic material, tests shall be done
according to the requirements of Annex 6.

6. ILLUMINATION
6.1. General Provisions
6.1.1. Headlamps shall be so made that they give adequate illumination without dazzle when
emitting the passing beam, and good illumination when emitting a driving beam.
6.1.2. The luminous intensity produced by the headlamp shall be measured at 25m distance by
means of a photoelectric cell having a useful area comprised within a square of 65mm side.
The Point HV is the centre-point of the coordinate system with a vertical polar axis. Line H is
the horizontal through HV (see Annex 3 of this Regulation).
6.1.3. For Class A or B or C or D
6.1.3.1. Apart from (an) LED module(s), the headlamps shall be checked by means of an
uncoloured standard (étalon) filament lamp designed for a rated voltage of 12V. During the
checking of the headlamp, the voltage at the terminals of the filament lamp shall be
regulated so as to obtain the reference luminous flux at 13.2V as indicated at the relevant
data sheet of Regulation No. 37.
In order to protect the standard (étalon) filament lamp during the process of photometric
measurement it is permissible to carry out the measurements at a luminous flux that differs
from the reference luminous flux at 13.2V. If the test laboratory chooses to carry out
measurements in such a manner the luminous intensity shall be corrected by multiplying the
measured value by the individual factor F of the standard (étalon) filament lamp in order
to verify the compliance with the photometric requirements where:
F = Φ / Φ
Φ is the reference luminous flux at 13,2V as specified in the relevant data sheet of
Regulation No. 37
Φ
is the actual luminous flux used for the measurement.
6.1.3.2. Depending on the number of filament lamps for which the headlamp is designed, it shall be
considered acceptable if it meets the requirements of Paragraph 6 with the same number of
standard (étalon) filament lamp(s), which may be submitted with the headlamp.
6.1.3.3. LED module(s) shall be measured at 6.3V or 13.2V respectively, if not otherwise specified
within this Regulation. LED module(s) operated by an electronic light source control gear,
shall be measured as specified by the applicant.

6.2.2. The principal passing-beam shall be aimed so that:
6.2.2.1. For horizontal adjustment: The beam is as symmetrical as possible with reference to Line V-
V;
6.2.2.2. For vertical adjustment: The horizontal part of the "cut-off" line is adjusted to its nominal
position (0.57°) below the H-H Line.
If, however, vertical adjustment cannot be performed repeatedly to the required position
within the allowed tolerances, the instrumental method of Annex 9, Paragraphs 4 and 5 shall
be applied to test compliance with the required minimum quality of the "cut-off" line and to
perform the beam vertical adjustment.
6.2.3. When so aimed, the headlamp must, if its approval is sought solely for provision of a
passing beam, to comply with the requirements set out in Paragraphs 6.2.5. to 6.2.6.
below; if it is intended to provide both a passing beam and a driving beam, it shall comply
with the requirements set out in Paragraphs 6.2.5., 6.2.6. and 6.3.
6.2.4. Where a headlamp so aimed does not meet the requirements set out in Paragraphs 6.2.5.,
6.2.6. and 6.3., its alignment may be changed, except for headlamps that have no
mechanism to adjust horizontal aim, on condition that the axis of the beam is not displaced
laterally by more than 0.5° to the right or left and vertically by not more than 0.25° up or
down. To facilitate alignment by means of the “cut-off”, the headlamp may be partially
occulted in order to sharpen the "cut-off". However, the "cut-off" should not extend beyond
the Line H-H.
6.2.5. The passing beam shall meet the requirements as shown in the applicable table below and
the applicable figure as shown in Annex 3:
Notes:
For Class E headlamps the voltage applied to the terminals of the ballast(s) is either 13.2V ±
0.1V for 12V systems or as otherwise specified (see Annex 11).
"D" means under the H-H Line.
"U" means above the H-H Line.
"R" means right of the V-V Line.
"L" means left of the V-V Line.

producing a passing beam, only when the absolute value ∆r = │ r – r │ recorded on the
headlamp is not more than 1.0mrad (∆r ≤ 1.0mrad).
2.2.2. However, if this value is more than 1.0mrad but not more than 1.5mrad
(1.0mrad < ∆r ≤ 1.5mrad) a second headlamp shall be tested as described in
Paragraph 2.1. after being subjected three consecutive times to the cycle as described

ADHESIVE TAPE ADHERENCE TEST
1. PURPOSE
This method allows to determine under standard conditions the linear force of adhesion of an
adhesive tape to a glass plate.
2. PRINCIPLE
Measurement of the force necessary to unstick an adhesive tape from a glass plate at an
angle of 90°.
3. SPECIFIED ATMOSPHERIC CONDITIONS
The ambient conditions shall be at 23°C ± 5°C and 65 ± 15% RH.
4. TEST PIECES
Before the test, the sample roll of adhesive tape shall be conditioned for 24h in the specified
atmosphere (see Paragraph 3 above).
Five test pieces each 400mm long shall be tested from each roll. These test pieces shall be
taken from the roll after the first three turns were discarded.
5. PROCEDURE
The test shall be under the ambient conditions specified in Paragraph 3.
Take the five test pieces while unrolling the tape radially at a speed of approximately
300mm/s, then apply them within 15 seconds in the following manner:
Apply the tape to the glass plate progressively with a slight length-wise rubbing movement of
the finger, without excessive pressure, in such a manner as to leave no air bubble between
the tape and the glass plate.
Leave the assembly in the specified atmospheric conditions for 10min
Unstick about 25mm of the test piece from the plate in a plane perpendicular to the axis of the
test piece. Fix the plate and fold back the free end of the tape at 90°. Apply force in such a
manner that the separation line between the tape and the plate is perpendicular to this force
and perpendicular to the plate.
6. RESULTS
Pull to unstick at a speed of 300mm/s ± 30mm/s and record the force required.
The five values obtained shall be arranged in order and the median value taken as a result of
the measurement. This value shall be expressed in Newtons per centimetre of width of the
tape.

3.3. When the vertical adjustments of three different individuals differs by more than 0.2° for
Class B and 0.3° for Classes A, C, D and E headlamps, the horizontal part of the "cut-off" line
is assumed not to provide sufficient linearity or sharpness for performing visual adjustment. In
this case the quality of "cut-off" shall be tested instrumentally for compliance with
requirements as follows.
4. MEASUREMENT OF THE QUALITY OF "CUT-OFF"
4.1. Measurements shall be performed by vertically scanning through the horizontal part of the
"cut-off" line in angular steps not exceeding 0.05°
(a)
(b)
at either a measurement distance of 10m and a detector with a diameter of
approximately 10mm.
or at a measurement distance of 25m and a detector with a diameter of approximately
30mm.
The measurement of the "cut-off" quality shall be considered acceptable if the requirements of
the Paragraph 4.1.2 of this Annex shall comply with at least one measurement at 10m or
25m.
The measuring distance at which the test was determined shall be noted down in
Paragraph 9, Annex 1 "Communication form" of this Regulation.
The scanning is performed from its lower position upwards through the "cut-off" line along the
vertical lines at -3° to -1.5° and +1.5° to +3° from the V-V Line. When so measured, the
quality of the "cut-off" line shall meet the following requirements:
4.1.1. Not more than one "cut-off" line shall be visible.
4.1.2. Sharpness of "cut-off": if scanned vertically through the horizontal part of the "cut-off" line
along the ± 2.5 - lines, the maximum value measured for:
G = (log E - log E )
is called the sharpness factor G of the "cut-off" line. The value of G shall not be less than
0.13 for Class B and 0.08 for Classes A, C, D and E.
4.1.3. Linearity: the part of the "cut-off" line which serves for vertical adjustment shall be horizontal
from 3° L to 3° R of the V-V Line. This requirement is deemed to be met if the vertical
positions of the inflection points according to Paragraph 3.2 above at 3° left and right of the
V-V Line do not differ by more than 0.2° for Class B and 0.3° for Classes A, C, D and E
headlamps from the nominal position at the V-V Line.
5. INSTRUMENTAL VERTICAL ADJUSTMENT
if the "cut-off" line complies with the above quality requirements, the vertical beam
adjustment can be performed instrumentally. For this purpose the inflection point where
d (log E) / dv = 0 is positioned on the V-V Line in its nominal position below the H-H Line.
The movement for measuring and adjusting the "cut-off" line shall be upwards from below the
nominal position.

ANNEX 11
VOLTAGE MARKINGS
This marking must be placed on the main
body of each headlamp containing only
gas-discharge light sources and ballast, and on
each external part of the ballast.
The ballast(s) is(are) designed for a ** Volts
network system.
This marking must be placed on the
main body of each headlamp containing at
least one gas-discharge light source and
ballast.
The ballast(s) is(are) designed for a **
Volts network system.
None of the filament lamps which the
headlamp contains is designed for a 24V
network system.

3.3. Ageing
Upon the request of the applicant the LED module shall be operated for 48 h and cooled
down to ambient temperature before starting the tests as specified in this Regulation.
4. SPECIFIC SPECIFICATIONS AND TESTS
4.1. Colour Rendering
4.1.1. Red Content
In addition to measurements as described in Paragraph 7. of this Regulation, the minimum
red content of the light of a LED module or headlamp incorporating LED module(s) tested at
50V shall be such that:
k
=


E
E
( λ) V ( λ)
( λ) V ( λ)


≥ 0.05
where:
E (λ) (unit: W)
V(λ) (unit: 1)
is the spectral distribution of the irradiance;
is the spectral luminous efficiency;
(λ)
(unit: nm) is the wavelength.
This value shall be calculated using intervals of one nanometre.

4.3. Temperature Stability
4.3.1. Illuminance
4.3.1.1. A photometric measurement of the headlamp shall be made after 1min of operation for the
specific function at the test point specified below. For these measurements, the aim can be
approximate but must be maintained for before and after ratio measurements.
Test points to be measured:
Principal passing beam 50V
(For the measurement of bend lighting, the test point shall be specified by the manufacture.)
Driving beam H − V
4.3.1.2. The lamp shall continue operation until photometric stability has occurred. The moment at
which the photometry is stable is defined as the point in time at which the variation of the
photometric value is less than 3% within any 15min period. After stability has occurred, aim
for complete photometry shall be performed in accordance with requirements of specific
device. Photometer the lamp at all test points required for the specific device.
4.3.1.3. Calculate the ratio between the photometric test point value determined in
Paragraph 4.3.1.1. and the point value determined in Paragraph 4.3.1.2.
4.3.1.4. Once stability of photometry has been achieved, apply the ratio calculated above to each of
the remainder of the test points to create a new photometric table that describes the
complete photometry based on 1min of operation.
4.3.1.5. The luminous intensity values, measured after 1min and after photometric stability has
occurred, shall comply with the minimum and maximum requirements.
4.3.2. Colour
The colour of the light emitted measured after 1min and measured after photometric stability
has been obtained, as described in Paragraph 4.3.1.2. of this Annex, shall both be within
the required colour boundaries.

Headlamps - Symmetrical Passing/Driving Beam - Filament, Gas-discharge Light Sources or LED Modules.
