UN R53: Proposal for Supplement 3 to the 02 series of amendments
Download in .pdf format Download in .docx format

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.
