Correct use of the lighting and signalling system --> Road Traffic Code - The technical condition of the vehicles and the lighting and luminous signalling system

ECE-UN Regulation no. 6 - Uniform provisions concerning the approval of direction indicator lamps for motor vehicles and their trailers

Art.8. "The colour of the light emitted inside the field of the light distribution grid defined in point 2 of Annex 4 is auto-yellow. For testing, see Annex 5 to this regulation. Outside this field, no pronounced colour variation is observed. These provisions also apply within the interval of variable luminous intensity produced by the direction indicator lamps in category 2b."

This legal article is addressed strictly to the manufacturers and producers of these devices.
