Document Title	UN R53: Proposal for Supplement 3 to the 02 series of amendments
Reference Number	WP.29/2019/85
Date	27 Aug 2019
Summary	Proposal to align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps; to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device. restore the definition of “device” (because the definition under UN R53 differs from that under UN R48) delete the definitions of “bend lighting”, “H plane”, “sequential activation” and “emergency stop signal” (because they are identical to the definitions in UN R48), and introduce requirements for light emitting diode (LED) substitute light sources.
