Proposal to define specifications for the design and operation of external status indicators for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers under UN R48 pursuant to provisions of UN R97 and R116.

Japan proposals, modified pursuant to discussions during the 79th GRE session, to improve human-machine interfaces and otherwise clarify elements in the Headlamp Switching Task Force proposal for the electrical connections of headlamps, daytime running lamps, and related lighting devices (documents GRE/2018/20 and GRE-78-21/Rev.1).

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.

Discussion document from the Netherlands and Italy to serve presenting potential new requirements for headlamp levelling, in particular regarding the vertical inclination in relation to the dipped-beam headlamp mounting height. The proposal is based on the original proposal of the Informal Working Group on Visibility, Glare and Levelling (VGL) (informal documents GRE-78-23-Rev.1, GRE-78-32, GRE-78-36) and discussions during the GRE 78th session.
