Proposal prepared by the SLR informal group in cooperation with IMMA in order to delete definitions in UN R74.01 made redundant because they already exist in UN R48. The aim of this proposal is to confirm UN R48 as the sole 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.
