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 in paragraph 2 of Annex 4 shall be within the limits of the coordinates prescribed in Annex 5 to this Regulation. Outside this field, no sharp variation 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. 8.1. The side-marker lamp must emit amber light; however it can emit red, if the rearmost side-marker lamp is grouped or combined or reciprocally incorporated with the rear position lamp, the rear end-outline marker lamp, the rear fog lamp, the stop lamp, or is grouped with or has part of the light emitting surface in common with the rear retro-reflector.
8.2. The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 4 must be within the limits of the trichromatic 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.
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. 8.1. The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 3 shall be within the limits of the coordinates prescribed in Annex 4 to this Regulation. It shall be measured under the conditions as prescribed in paragraph 7. Outside this field, no sharp variations of colour shall be observed. 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, from the lamp body but supplied by the lamp manufacturer as part of the lamp system.
Colour of light emitted. Stop lamps and rear position lamps shall emit red light, front position lamps shall emit white light, direction indicators shall emit amber light. The colour of the light emitted inside the field of the light distribution grid defined at paragraph 2. of Annex 4, shall be measured using a light source having a colour temperature of 2,856 K, 3/ in accordance with 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, the colorimetric characteristics should be verified with the light sources present in the lamps at a voltage of 6.75 V, 13.5 V or 28.0 V.
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)).
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.
