ECE/TRANS/WP.29/2018/157
PROPOSAL FOR A NEW UN REGULATION ON
LIGHT-SIGNALLING DEVICES (LSD)
(ECE 148-00)
ADOPTED AT THE 177 SESSION – MARCH 2019
PROVISIONAL DATE OF ENTRY INTO FORCE: NOVEMBER 15, 2019

INTRODUCTION
This Regulation combines the provisions of individual UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87
and 91 into a single Regulation, and is the outcome of the World Forum for Harmonization of Vehicle
Regulations (WP.29) decision to simplify the lighting and light-signalling Regulations based on the initial
proposal by the European Union and Japan.
The objective of this Regulation is to increase the clarity, to consolidate and streamline the complexity of
requirements in UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87 and 91 and to prepare for the future
transition to performance based requirements, by reducing the number of Regulations through an
editorial exercise without changing any of the detailed technical requirements already in force up to the
date of entry into force of this Regulation.
Although this Regulation departs from the traditional approach of having a separate Regulation for each
lamp, by combining all light signalling lamps into a single Regulation, this simplified Regulation contains
all provisions and operates according to the existing structure of series of amendments, their transitional
provisions and supplements. The transitional provisions associated with a new series of amendments to
this Regulation will be identified for each device as applicable, this also includes a list of devices and
their applicable change indexes relating to the series of amendments.
It is expected that all Contracting Parties to the 1958 Agreement will adopt this Regulation and will
provide detailed explanation in case they are not in a position to adopt particular lamps. These decisions
will be registered in ECE/TRANS/WP.29/343 that records the status of the annexed Regulations and of
the amendments.
Regarding the requirements for approval markings, this Regulation includes the requirements for the use
of the "Unique Identifier" and is conditional upon access to a secure internet database established by
UNECE (in accordance with Schedule 5 of the 1958 Agreement) where all type approval documentation
is held. When the "Unique Identifier" is used there is no requirement for the lamps to carry the
conventional type approval markings (E-mark). If it is technically not possible to use the "Unique
Identifier" (e.g. if the access to the UNECE internet database cannot be secured or the database is not
operational), the use of conventional type approval markings is required until the use of the "Unique
Identifier" is enabled.

Nevertheless, direction indicators capable of being activated in different modes (sequential
or not) without any modification of the optical characteristics of the lamp do not constitute
"Direction indicators of different types".
A change of the colour of the light source or the colour of any filter does not constitute a
change of type.
3. ADMINISTRATIVE PROVISIONS

(c) A stop lamp Category S2 emitting more than the maximum value of Category S1;
(d) A stop lamp Category S4 emitting more than the maximum value of Category S3;
(e)
A direction indicator of Category 2b emitting more than the maximum value of
Category 2a;
(f) A rear fog lamp of Category F2 emitting more than the maximum value of Category F1.
Requirements of steady luminous intensity of the respective category shall be fulfilled
automatically.
4.7. Test Conditions
4.7.1. All measurements, photometric and colorimetric, shall be made:
4.7.1.1. In case of a lamp with replaceable light source, if not supplied by an electronic light source
control gear or a variable intensity control, with an uncoloured or coloured standard light
source of the category prescribed for the device, supplied with the voltage:
(a)
(b)
In the case of filament light source(s), that is necessary to produce the reference
luminous flux required for that Category of filament light source;
In the case of LED light source(s) of 6.75V, 13.5V or 28.0V; the luminous flux value
produced shall be corrected. The correction factor is the ratio between the objective
luminous flux and the value of the luminous flux found at the voltage applied.
4.7.1.2. In the case of a light source, which is operated independently from vehicle supply voltage
and fully controlled by the system, or in the case of a light source supplied by a special
power supply, the test voltage as specified by the applicant shall be applied to the input
terminals of the light source or 6.75V, 13.5V or 28.0V shall be applied to the input terminals
of that system/power supply. The test laboratory may require from the manufacturer this
special power supply needed to supply the light sources.

4.8. Photometric Measurements
4.8.1. Measurement Provisions
4.8.1.1. During photometric measurements, stray reflections shall be avoided by appropriate
masking.
4.8.1.2. In case the results of measurements should be challenged, measurements shall be carried
out in such a way as to meet the following requirements:
4.8.1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the
distance is applicable;
4.8.1.2.2. The measuring equipment shall be such that the angular aperture of the receiver viewed
from the reference centre of the light is comprised between 10' and 1°;
4.8.1.2.3. The intensity requirement for a particular direction of observation shall be deemed to be
satisfied if that requirement is met in a direction deviating by not more than one-quarter of a
degree from the direction of observation.
4.8.1.3. In the case where the lamp may be installed on the vehicle in more than one or in a field of
different positions the photometric measurements shall be repeated for each position or for
the extreme positions of the field of the reference axis specified by the manufacturer.
4.8.2. Measurement Methods
4.8.2.1. The photometric performance shall be checked in accordance with the relevant
sub-paragraph of Paragraph 4.7.
4.8.2.2. For multiple replaceable light sources:
When equipped with light source(s) at 6.75V, 13.5V or 28.0V, the luminous intensity values
produced shall be corrected. For these replaceable filament light sources the correction
factor is the ratio between the reference luminous flux and the mean value of the luminous
flux found at the voltage applied (6.75V, 13.5V or 28.0V).
For LED light sources the correction factor is the ratio between the objective luminous flux and
the mean value of the luminous flux found at the voltage applied (6.75V, 13.5V or 28.0V).
The actual luminous fluxes of light source used shall not deviate more than 5% from the
mean value. Alternatively, and in case of filament light sources only, a standard filament
light source may be used in turn, in each of the individual positions, operated at its reference
flux, the individual measurements in each position being added together.

4.8.5. An interdependent lamp system shall meet the requirements when all its interdependent
lamps are operated together.
However:
(a)
(b)
If the interdependent lamp system providing the rear position lamp is partly mounted
on the fixed component and partly mounted on a movable component, the
interdependent lamp(s) specified by the applicant shall meet the outboard geometric
visibility colorimetric and photometric requirement, at all fixed positions of the
movable component(s). In this case, the inboard geometric visibility requirement is
deemed to be satisfied if this (these) interdependent lamp(s) still conform to the
photometric values prescribed in the field of light distribution for the approval of the
device, at all fixed positions of the moveable component(s);
If the interdependent lamp system providing the rear direction indicator function is
partly mounted on the fixed component and partly mounted on a movable component,
the interdependent lamp(s) specified by the applicant shall meet the geometric
visibility, colorimetric and photometric requirement, at all fixed positions of the
movable component(s). This does not apply to interdependent direction indicator
lamp(s) intended for fitting on vehicle(s) where, to fulfil or complete the geometric
visibility angle, additional lamps are activated when the movable component is in any
fixed open position, provided that these additional lamps satisfy all the position,
photometric and colorimetric requirements applicable to the direction indicator lamps
installed on the movable component.
4.8.6. The provisions of the relevant paragraphs of Annex 3 on local variations of intensity must be
observed.
4.8.7. If not otherwise specified, the intensities shall be measured with the light source
continuously alight and, in the case of lamps emitting red light, in coloured light.
4.8.8. In the case of lamps of Categories R2, RM2, S2, S4, F2 and 2b, the time that elapses
between energising the light source(s) and the light output measured on the reference axis
to reach 90% of the value measured in accordance with Paragraph 5 shall be measured for
the extreme levels of luminous intensity produced by the lamp. The time measured to obtain
the lowest luminous intensity shall not exceed the time measured to obtain the highest
luminous intensity.
4.8.9. The variable intensity control shall not generate signals which cause luminous intensities:
4.8.9.1. Outside the range specified in Paragraph 5; and
4.8.9.2. Exceeding the respective steady luminous intensity maximum specified in Paragraph 5 for
the specific lamp:
(a)
For systems depending only on daytime and night time conditions: under night time
conditions;
(b) For other systems: under standard conditions .
4.8.10. Particulars of the methods of measurement to be used are given in Annex 3.

5.1.2. Outside the reference axis and within the angular fields defined in the diagrams in Part A of
Annex 2, the intensity of the light emitted by each lamp must in each direction
corresponding to the points in the table of standard light distribution reproduced in

multiplied by the percentage specified in the said table of the direction in question.
5.1.3. Throughout the fields defined in the diagrams in Part A of Annex 2, the luminous intensity of
the light emitted must be not less than 0.05cd for front position lamps and front end-outline
marker lamps;
5.1.4. The colour of the light emitted shall be white, however the lamp identified by Symbol 'MA'
may be amber.

Be not less than the minimum specified in Paragraph 5.6.1., multiplied by the percentage
specified in the said table of the direction in question.

5.6.8. The variable intensity control shall not generate signals which cause luminous intensities
outside the range specified in Paragraph 5.6.1. and exceeding the Category 2a maximum
specified in Paragraph 5.6.1.:
(a)
For systems depending only on daytime and night time conditions: under night time
conditions;
(b) For other systems: under reference conditions as demonstrated by the

range of variable luminous intensity produced by rear direction indicator lamps of Category 2b.
5.6.10. For any direction indicator lamp except those equipped with filament light source(s), the
luminous intensities measured after one minute and after 30min of operation in flashing
mode (f = 1.5Hz, duty factor 50%), shall comply with the minimum and maximum
requirements. The luminous intensity distribution after one minute of operation can be
calculated by applying at each test point the ratio of luminous intensity measured in HV after
1min and after 30min of operation as above described.
5.6.11. For direction indicator lamps of Categories 1, 1a, 1b, 2a or 2b the flash may be produced by
sequential activation of their light sources if the following conditions are met:
(a)
(b)
(c)
(d)
(e)
Each light source, after its activation, shall remain lit until the end of the ON cycle;
The sequence of activation of the light sources shall produce a signal which proceeds
in a uniform progressive manner from inboard towards the outboard edge of the light
emitting surface;
It shall be one signal with no interruption and no vertical oscillations (e.g. not more
than one change of direction along the vertical axis). The distance between two
adjacent/tangential distinct parts of the light emitting surface of the sequential

reference axis, instead of the values defined in Paragraph 5.7.2. of UN Regulation 48.
These interruptions of the signal shall not create any overlap in the vertical axis
between the different parts, from inboard towards the outboard of the vehicle, and
shall not be used for any other lighting or light signalling functions;
The variation shall finish no more than 200ms after the beginning of the ON cycle;
The orthogonal projection of the light emitting surfaces of the direction indicator in the
direction of the axis of reference shall be circumscribed by a rectangle on a plane
normal to the axis of reference and having its longer sides parallel to the H-plane. The

2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER
For each type of lamp, the holder of the type approval 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 and colorimetric
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 lamps shall be selected at random from the production of a uniform batch. A
uniform batch means a set of lamps 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

ANNEX 5
MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR
1. GENERAL PROVISIONS
1.1. The conformity requirements shall be considered satisfied from a mechanical and a geometric
standpoint, in accordance with the requirements of this Regulation, if any, if the differences do
not exceed inevitable manufacturing deviations.
1.2. With respect to photometric performance, the conformity of mass-produced lamps shall not be
contested if, when testing the photometric performances set forth in Paragraph 4.7. of this
Regulation of any lamp chosen at random:
(a) No measured value deviates from the values prescribed in Paragraph 1.2.1. in Annex 4.
(b)
If, in the case of a lamp equipped with a replaceable light source and if results of the test
described above do not meet the requirements, tests on lamps shall be repeated using
another standard light source.
1.3. Lamps with apparent defects are disregarded.
1.4. The chromaticity coordinates shall be complied when tested under conditions of Paragraph 4.7.
of this Regulation.
2. FIRST SAMPLING
Four lamps are selected at random. The first sample of two is marked A, the second sample of
two is marked B.
2.1. The conformity of mass-produced lamps shall not be contested if the deviation of any specimen
of Samples A and B (all four lamps) is not more than 20%.
In the case, that the deviation of both lamps of Sample A is not more than 0% the
measurement can be terminated.
2.2. The conformity of mass-produced lamps shall be contested if the deviation of at least
one specimen of Samples A or B is more than 20%.
The manufacturer shall be requested to bring its production in line with the requirements
(alignment) and a repeated sampling according to Paragraph 3 shall be carried out within
two months' time after the notification. The Samples A and B shall be retained by the Technical
Service until the entire CoP process is finished.

ANNEX 6
HEAT RESISTANCE TEST FOR REAR FOG LAMPS AND DAYTIME RUNNING LAMPS
1. The lamp shall be subjected to a one-hour test of continuous operation following a warm-up
period of 20min. The ambient temperature shall be 23°C ± 5°C. The light source used shall be
a light source of the category specified for the lamp, and shall be supplied with a current at a
voltage such that it gives the specified average power at the corresponding test voltage.
However, for lamps equipped with non-replaceable light sources (filament light sources and
other), the test shall be made with the light sources present in the lamp, in accordance with
Paragraph 5.4.1. of this Regulation.
2. Where only the maximum power is specified, the test shall be carried out by regulating the
voltage to obtain a power equal to 90% of the specified power. The specified average or
maximum power referred to above shall in all cases be chosen from the voltage range of 6, 12
or 24V at which it reaches the highest value; for lamps equipped with non-replaceable light
sources the test conditions set in Paragraph 5.9.1. of this Regulation shall be applied.
2.1. In the case of light sources operated by an electronic control gear to obtain variable luminous
intensity, the test shall be carried out under the conditions given at minimum 90% of the higher
luminous intensity.
3. After the lamp has been stabilized at the ambient temperature, no distortion, deformation,
cracking or colour modification shall be perceptible. In case of doubt the intensity of light shall
be measured according to Paragraph 5 of this Regulation. At that measurement the values
shall reach at least 90% of the values obtained before the heat resistance test on the same
lamp.
