Technical requirements of Regulation No 7 of the United Nations' Economic Commission for Europe referred to in Article 3 and in Annex II, item 2.1 of Commission Directive 97/30/EC (1) adapting to technical progress Council Directive 76/758/EEC relating to the end-outline marker lamps, front position (side) lamps, rear position (side) lamps, stop lamps, daytime running lamps and side marker lamps for motor vehicles and their trailers 1. DEFINITIONS For the purposes of this Regulation,1.1. 'Front position (side) lamp` means the lamp used to indicate the presence and the width of the vehicle when viewed from the front;1.2. 'Rear position (side) lamp` means the lamp used to indicate the presence and the width of the vehicle when viewed from the rear;1.3. 'Stop-lamp` means the lamp used to indicate to other road-users to the rear of the vehicle that its driver is applying the service brake.The stop-lamps may be activated by the application of a retarder or a similar device.1.4. 'End-outline marker lamp` means a lamp fitted near to the extreme outer edges and as close as possible to the top of the vehicle and intended to indicate clearly the vehicle's overall width. In the case of certain power-driven vehicles and trailers, this lamp is intended to complement the vehicle's position (side) lamps and draw special attention to its outline;1.5. 'Definitions of terms`The definitions given in Regulation No 48 and its series of amendments in force at the time of application for type approval shall apply to this Regulation.1.6. 'Front and rear position (side) lamps, stop-lamps and end-outline marker lamps of different types` means lamps which differ in each said category in such essential respects as:- The trade name or mark,- The characteristics of the optical system, (levels of intensity, light distribution angles, type of filament lamp, etc.),- The system used to reduce illumination at night - in the case of stop-lamps with two levels of intensity.5. GENERAL SPECIFICATIONS 5.1. Each device supplied shall conform to the specifications set forth in paragraphs 6 and 8 below.5.2. The devices must be so designed and constructed that in normal conditions of use, and notwithstanding the vibrations to which they may be subjected in such use, their satisfactory operation remains assured and they retain the characteristics prescribed by this Regulation.5.3. Lamps having been approved as front or rear position (side) lamps, are deemed being also approved end-outline marker lamps.5.4. Front and rear position (side) lamps which are grouped or combined or reciprocally incorporated may also be used as end-outline marker lamps.6. INTENSITY OF LIGHT EMITTED 6.1. In the reference axis, the light emitted by each of the two devices supplied must be of not less than the minimum intensity and of not more than the maximum intensity specified below:>TABLE>6.2. Outside the reference axis and within the angular fields defined in the diagrams in annex 1 to this Regulation, the intensity of the light emitted by each of the two devices supplied must:6.2.1. In each direction corresponding to the points in the light distribution table reproduced in annex 4 to this Regulation, be not less than the product of the minimum specified in paragraph 6.1. above by the percentage specified in the said table for the direction in question;6.2.2. In no direction within the space from which the light-signalling device is visible, exceed the maximum specified in paragraph 6.1. above;6.2.3. However, a luminous intensity of 60 cd shall be permitted for rear position (side) lamps reciprocally incorporated with stop-lamps (see paragraph 6.1.3. above) below a plane forming an angle of 5° with and downward from the horizontal plane;6.2.4. Moreover,6.2.4.1. Throughout the fields defined in the diagrams in annex 1, the intensity of the light emitted must be not less than 0.05 cd for front and rear position (side) lamps and end-outline marker lamps, not less than 0.3 cd for stop-lamps with one level of intensity, and for stop-lamps with two levels of intensity 0.3 cd by day and 0.07 cd by night;6.2.4.2. If a rear position (side) lamp is reciprocally incorporated with a stop-lamp, the ratio between the luminous intensities actually measured of the two lamps when turned on simultaneously at the intensity of the rear position (side) lamp when turned on alone should be at least 5: 1 in the field delimited by the straight horizontal lines passing through ±5° V and the straight vertical lines passing through ±10° H of the light distribution table. If the stop-lamp has two levels of intensity, this requirement must be satisfied when the night condition is switched on;6.2.4.3. The provisions of paragraph 2.2. of annex 4 to this Regulation on local variations of intensity must be observed.6.3. The intensities shall be measured with the filament lamp(s) continuously alight and, in the case of devices emitting selective-yellow or red light, in coloured light.6.4. In the case of a stop-lamp providing two levels of intensity the time that elapses between electrical supply being switched on and the light output measured on the reference axis to reach 90 % of the value measured in accordance with paragraph 6.3. above shall be measured for both the day and the night conditions of use. The time measured for the night condition of use shall not exceed that measured for the day condition of use.6.5. Annex 4, to which reference is made in paragraph 6.2.1. above, gives particulars of the methods of measurement to be used.7. TEST PROCEDURE 7.1. All measurements shall be made with a white standard filament lamp of the category prescribed for the device, the supply voltage being so regulated as to produce the normal luminous flux prescribed for that category of lamp.7.1.1. All measurements on lamps equipped with non-replaceable light sources (filament lamps and other) shall be made at 6.75 V, 13.5 V or 28.0 V respectively.In the case of light sources supplied by a special power supply, the above test voltages shall be applied to the input terminals of that power supply. The test laboratory may require from the manufacturer the special power supply needed to supply the light sources.7.2. However, in the case of a stop-lamp for which an additional system is used to obtain the night-time intensity, the voltage applied to the system for measuring the night-time intensity shall be that which was applied to the filament lamp for measuring the day-time intensity.(2)7.3. Where a rear position (side) lamp is reciprocally incorporated with a dual-intensity stop-lamp and is designed to operate permanently with an additional system to regulate the intensity of the light emitted, measurement of the light emitted shall be performed with the same voltage applied to the system as would, if applied to the filament lamp, enable the lamp to produce the prescribed normal luminous flux.7.4. The vertical and horizontal outlines of the illuminating surface of a light-signalling device (paragraph 1.6.2.) shall be determined and measured in relation to the centre of reference (paragraph 1.6.5.).Note:8. COLOUR OF LIGHT EMITTED The colour of the light emitted shall be within the limits of the co-ordinates prescribed for the colour in question in annex 5 to this Regulation.(1) The functioning and installation conditions of these additional systems will be defined by special provisions.(2) OJ No L 171, 30. 6. 1997, p. 25.ANNEX 1 Front and rear position (side) lamps, end-outline marker lamps and stop-lamps: minimum angles required for light distribution in space of these lamps (1) The minimum vertical angles of light distribution in space are 15° above and 15° below the horizontal for all categories of devices included in this Regulation except for category S3 stop lamp for which they are 10° above and 5° below the horizontal.Minimum horizontal angles of light distribution in space >REFERENCE TO A GRAPHIC>>START OF GRAPHIC>Front position (side) lamps end-outline marker lamps>END OF GRAPHIC>>REFERENCE TO A GRAPHIC>>START OF GRAPHIC>Rear position lamps end-outline marker lamps>END OF GRAPHIC>>REFERENCE TO A GRAPHIC>>START OF GRAPHIC>Stop-lamps (S1 and S2)>END OF GRAPHIC>>REFERENCE TO A GRAPHIC>>START OF GRAPHIC>Stop-lamps (S3)>END OF GRAPHIC>Note:(1) The angles shown in these diagrams are correct for devices to be mounted on the right side of the vehicle. The arrows point to the front of the vehicles.ANNEX 4 Photometric measurements 1. MEASUREMENT METHODS 1.1. During photometric measurements, stray reflections shall be avoided by appropriate masking.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:1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable;1.2.2. The measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the lamp is comprised between 10 angular minutes and one degree;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.2. TABLE OF STANDARD LIGHT DISTRIBUTION >REFERENCE TO A GRAPHIC>>TABLE>2.1. The direction H = 0° and V = 0° corresponds to the reference axis. (On the vehicle it is horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility). It passes through the centre of reference. The values shown in the table give, for the various directions of measurement, the minimum intensities as a percentage of the minimum required in the axis for each lamp (in the direction H = 0° and V = 0°).2.2. Within the field of light distribution of paragraph 2, schematically shown as a grid, the light pattern should be substantially uniform, i.e. the light intensity in each direction of a part of the field formed by the grid lines shall meet at least the lowest minimum value being shown on the grid lines surrounding the questioned direction as a percentage.3. PHOTOMETRIC MEASUREMENT OF LAMPS EQUIPPED WITH SEVERAL LIGHT SOURCES The photometric performance shall be checked:3.1. For non-replaceable light sources (filament lamps and other):with the light sources present in the lamp, in accordance with paragraph 7.1.1. of this Regulation.3.2. For replaceable filament lamps:when equipped with mass production filament lamps at 6.75 V, 13.5 V or 28.0 V the luminous intensity values produced shall lie between the maximum limit given in this Regulation and the minimum limit of this Regulation increased according to the permissible deviation of the luminous flux permitted for the type of filament lamp chosen, as stated in Regulation No. 37 for production filament lamps; alternatively a standard filament lamp 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.ANNEX 5 Colours of lights >TABLE>For checking these colorimetric characteristics, a source of light at a colour temperature of 2,856K corresponding to illuminant A of the International Commission on Illumination (CIE) shall be used. However, for lamps equipped with non-replaceable light sources (filament lamps and other), the colorimetric characteristics should be verified with the light sources present in the lamp, in accordance with paragraph 7.1.1. of this Regulation.
