Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 4 shall be amber. Outside this field, no sharp variation of colour shall be observed. To check these colorimetric characteristics, the test procedure described in paragraph 7. of this Regulation shall be applied. These requirements shall also apply within the range of variable luminous intensity produced by direction indicators of category 2b. 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 relevant subparagraphs of paragraph 7.1. of this Regulation.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 3 shall be white. For testing see Annex 4 to this Regulation. Outside this field, no sharp variations of colour shall be observed.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined at paragraph 2. of Annex 4, measured by using a source of light with a colour temperature of 2,856 K, corresponding to illuminant A of the International Commission on Illumination (CIE), shall be within the limits of the co-ordinates prescribed for the colour in question in Annex 5 to this Regulation. Outside this field no sharp variation of colour shall be observed. 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 8.1. of this Regulation.
Colour of light emitted. In the case of reversing lamps the colour of the light emitted inside the field of the light distribution grid defined at paragraph 2. of Annex 3 shall be white. In the case of manoeuvring lamps the colour of the light emitted inside the field of the whole light distribution shall be white. To check these colorimetric characteristics, the test procedure described in paragraph 7. of this Regulation shall be applied. Outside this field no sharp variation of colour shall be observed. However, for lamps equipped with non-replaceable light sources (filament light sources and other), the colorimetric characteristics should be verified with the light sources present in the lamp, in accordance with relevant subparagraphs of paragraph 7.1. of this Regulation.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid as specified in each Regulation shall be within the limits of the coordinates prescribed in Annex 4 “COLOUR OF LIGHTS” of Part II to this Regulation (Horizontal Reference Document (HRD)). Outside this field, no sharp variation of colour shall be observed. These requirements shall also apply within the range of variable luminous intensity produced by variable intensity lamps.
Colour of light emitted. 8.1. The colour of the light emitted shall be white.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined at paragraph 3 of annex 3, which shall be measured by using a source of light at a colour temperature of 2856 K, */ must lie within the limits of the following trichromatic co-ordinates: limit towards yellow: y < 0.335 limit towards purple: y ≥ 0.980 - x 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. of this Regulation.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined at paragraph 2. of Annex 4 shall be red, white or amber. To check these colorimetric characteristics, the test procedure described in paragraph 8. of this Regulation shall be applied. Outside this field no sharp variation of colour shall be observed. 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 relevant subparagraphs of paragraph 8.1. of this Regulation. 3 For the purpose of this Regulation "being part of the lamp" means to be physically included in the lamp body or to be external, separated or not, but supplied by the lamp manufacturer as part of the lamp system. The functioning and installation conditions of these additional systems will be defined by special provisions.
Colour of light emitted. The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 2 shall be red or white. Outside this field, no sharp variation of colour shall be observed. To check these colorimetric characteristics, the test procedure described in paragraph 7. shall be applied. However, for lamps equipped with non-replaceable light sources, the colorimetric characteristics should be verified with the light sources present in the lamp, in accordance with the relevant sub-paragraph of Annex B 5 of Regulation No. 48. . The colour of the light emitted shall lie inside the chromaticity areas defined by the boundaries in Annex B4 of Regulation No. 48. In the case of a category S3 or S4 stop lamp, which is intended to be mounted inside the vehicle, the colorimetric characteristics shall be verified with the worst case combination(s) of lamp and rear window(s) or sample plate(s). These requirements shall also apply within the range of variable luminous intensity produced by:
Colour of light emitted. The colour of the light emitted for any head lamp shall be white and shall be within the limits of the coordinates prescribed in Annex 4 of Part II to this Regulation (Horizontal Reference Document (HRD)).
