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.

During April 2016, Japan presented a study to GRE-75 on the disturbance due to the use of motorcycle daytime running lamps (DRL) at night (see GRE-75-09). A proposal (GRE/2016/35 supported by GRE-76-03) for automatic switching between DRL and headlamps was then presented during October 2016 at GRE-76. Italy, among others, raised a reservation. This document details Italy’s concerns with the proposal by Japan.

Proposal from the special interest group of experts for DRL-L to introduce requirements for automatic switching from daytime running lamps (“DRL”) to headlamp(s) if maximum luminous intensity of DRL is above 700 cd.

Two part proposal to a) make the fitting of front position lamps optional and b) allow for its separate control under certain conditions and for rear positions lamps and registration plate lamps to be lit during the period between the activation of the master switch and the engine start.

Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 02 series of Regulation No. 53.

Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 01 series of Regulation No. 53.

Proposal from the informal working group on the Simplification of Lighting Regulations to introduce the definition and general requirements for use of the “change index” established via the three new simplified Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD).

Proposal to require automatic switching from DRL to normal headlamp lighting as conditions warrant, amending the current UN R53 as well as the proposed new UN Regulation on light-signalling devices.

Proposal to clarify the text with regard to the activation of the direction indicators when the motorcycle engine in order to signal the vehicle status. The proposal would specify the purposes for which indicators may be activated:

1. To show the vehicle status (e.g. locking system) when the vehicle is parked;
2. To allow the driver to recognize the presence of his/her own vehicle from a certain distance by remote control;
3. In case of keyless entry system and of the driver having lost the key fob while riding – to inform the driver that he/she no longer has the key fob and that the vehicle will soon become unable to restart.

Proposal to allow installation of exterior courtesy lamps on motorcycles by aligning the text with provisions on courtesy lamps in UN R48.

Proposal to align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps.

Proposal to update the definition of “stop lamp” in order 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.

Proposal prepared by the SLR informal group in cooperation with IMMA to delete definitions in UN R53.02 made redundant because identical definitions already exist in UN R48. The aim of this submission is to confirm UN R48 as the repository for common definitions used across all lighting regulations.

Proposal from the SLR informal group to improve the general requirements proposed in documents GRE/2018/16 and GRE/2018/18.

Because the new lighting device regulations (LSD, RRD, and RID) each cover multiple lighting functions (e.g. direction indicators, marker lamps, DRL in the LSD regulation), the potential exists for a change in stringency to impact some, but not all functions within the scope of each regulation. The change index is proposed in order to track the impact on each function and so restrict the need for new type approvals only to those functions impacted by a change in stringency.

Proposal from the SLR informal group to improve and correct the official documents to introduce references to the three new simplified UN Regulations on LSD, RID and RRD.

Proposal for changes to document GRE/2018/19 proposing to require automatic switching from DRL to normal headlamp lighting as conditions warrant under UN R53 and the proposed new UN Regulation on light-signalling devices.
