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.

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.

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.
