Proposal to explicitly allow direction indicators to be activated when the motorcycle engine is stopped in order to signal the vehicle status. Some motorcycles currently offer this feature; however, it is not clear whether the scope of Regulation No. 53 covers and allows this function.

Proposal to remove the prohibition against lamps “reciprocally incorporated” with any other lamp. This proposal would align UN R53 with UN R48 and correct an oversight from a previous amendment process.

Proposal to update the definition of “stop lamp” (in line with similar definitions in UN R7 and UN R48) so that it would allow the use of different stop lamp activation methods for powered two-wheelers (e.g. by the application of a retarder or a similar device). A corresponding proposal for amendments to Regulation No. 78 (GRRF/2017/14) has been submitted to the September 2017 session of the Working Party on Braking and Running Gear.

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.
