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, and to make editorial corrections.
This proposal (WP.29/2019/86) was adopted by the World Forum. Thirty-five Contracting Parties out of the 46 applying UN R53 were present for the vote by AC.1. Thirty-five voted in favor with zero against and zero abstaining.
