... Introduction a0c0
... 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. a0c0
... 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. a0c0
... 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. a0c0
... 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. a0c0
... 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. a0c0
1. Scope a0c0
... This Regulation applies to the following lamps: a0c0
... Rear-registration plate illuminating lamps a0c0
... Direction indicator lamps a0c0
... Position lamps a0c0
... Stop lamps a0c0
... End-outline marker lamps a0c0
... Reversing lamps a0c0
... Manoeuvring lamps a0c0
... Rear fog lamps a0c0
... Parking lamps a0c0
... Daytime running lamps a0c0
... Side marker lamps a0c0
2. Definitions a0c0

2.1. All the definitions given in the latest series of amendments to UN Regulation No. 48 in force at the time of application for type approval shall apply, unless otherwise specified in this Regulation or in the pertinent installation UN Regulations Nos. 53, 74 and 86. a1c0
2.2. "Lamps of different types" means lamps, which differ in such essential respects as: a0c0
... (a) The trade name or mark: a0c0
... (i) Lamps bearing the same trade name or mark but produced by different manufacturers are considered as being of different types; a0c0
... (ii) Lamps produced by the same manufacturer differing only by the trade name or mark are considered as being of the same type. a0c0

A5  A second repeated sampling according to paragraph 4 shall be carried out within two months' time after the notification. The samples C and D shall be retained by the Technical Service until the entire COP process is finished. a0c0
A5 3.2.2. One specimen of samples C or D is more than 30 per cent. In this case the approval shall be withdrawn and paragraph 5 shall be applied. a0c0
A5 4. Second repeated sampling a0c0
A5  A sample of four lamps is selected at random from stock manufactured after alignment. The first sample of two is marked E, the second sample of two is marked F. a0c0
A5 4.1. The conformity of mass-produced lamps shall not be contested if the deviation of any specimen of samples E and F (all four lamps) is not more than 20 per cent. In the case, that the deviation of both lamps of sample E is not more than 0 per cent the measurement can be terminated. a0c0
A5 4.2. The conformity of mass-produced lamps shall be contested if the deviation of at least one specimen of samples E or F is more than 20 per cent. In this case the approval shall be withdrawn and paragraph 5 shall be applied. a0c0
A5 5. Approval withdrawn a0c0
A5  As required according to paragraphs 4.1. and 4.2., approval shall be withdrawn according to paragraph 3.6. of this Regulation. a0c0
A6  Annex 6 a0c0
A6  Heat resistance test for rear fog lamps and daytime running lamps a0c0
A6 1. The lamp shall be subjected to a one-hour test of continuous operation following a warm-up period of 20 minutes. 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. a0c0
A6 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 per cent 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 24 V 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. a0c0
A6 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 per cent of the higher luminous intensity. a0c0
A6 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 per cent of the values obtained before the heat resistance test on the same lamp. a0c0
A7  Annex 7 a0c0
A7  Arrangement of approval marks a0c0
A7  The following approval mark arrangements are given merely as examples and any other arrangement made in accordance with paragraph 3.3. of this Regulation is acceptable. a0c0
A7 1. Approval mark of a single light signalling lamp a0c0
A7  a0c0
A7 2. Approval mark of grouped, combined or reciprocally incorporated lamps a0c0
A7  Note: The vertical and horizontal lines schematize the shape of the light-signalling lamp. These lines are not part of the approval mark. a0c0
A7  Figure A7-III a0c0
A7  Marking example 3 a0c0
A7  a0c0
A7  These examples of approval marks represent two possible solutions for the marking of a light signalling lamp where two or more lamps are part of the same assembly of grouped, combined or reciprocally incorporated lamps a0c0
A7  They indicate that the lamp was approved in the Netherlands (E4) under approval number 3333 and comprises: a0c0
A7  (a) A retro-reflector of class 1A; a0c0
A7  (b) A rear direction indicator lamp with variable luminous intensity (category 2b). The horizontal arrow shows in what position this device, which cannot be mounted on either side of the vehicle indiscriminately, is to be mounted; a0c0
A7  (c) A rear position lamp with variable luminous intensity (R2). The horizontal arrow indicates the side on which the required photometric specifications are met up to an angle of 80° H; a0c0
A7  (d) A rear fog lamp with variable luminous intensity (F2); a0c0
A7  (e) A reversing lamp (AR); a0c0
A7  (f) A stop lamp with variable luminous intensity (S2). a0c0
A7  All these lamps (functions) are approved in accordance with the original series of amendments to this Regulation (148R) as indicated by the number (00) mentioned after 148R. a0c0
A7 3. Approval mark of a lamp where the lens is intended to be used in different types of lamps a0c0

A7  a0c0
A7  This example corresponds to the marking of a lens intended to be used in different types of light signalling lamps. The approval marks indicate that the lamp was approved in Spain (E9) under approval number 1432 and may comprise all listed different functions. a0c0
A7  The main body of the lamp shall bear the only valid approval mark. a0c0
A7 4. Identification code of light source modules a0c0
