UNECE R6 establishes technical and administrative criteria for the approval of driver-operated devices that signal a driver’s intention to change the direction in which his or her vehicle is proceeding.
The regulation applies solely to “fixed-position flashing light devices whose flashing is obtained by the intermittent supply of electric current to the lamp”.
This regulation will be superseded by a new UN Regulation on Light-Signalling Devices (LSD) under the Simplification of Lighting Regulations development program.
