6. GRE took note of the progress report of the Informal Working Group Simplification of the Lighting and Light-Signalling Regulations" (IWG SLR) (GRE-83-47). GRE agreed that IWG SLR would be chaired by Mr. Derwin Rovers (Netherlands).

7. GRE provided the following guidance to IWG SLR:

• GRE supported the proposed scientific notation for numbers (GRE-83-08);
• For the use of the Unique Identifier (UI), GRE agreed with the IWG SLR proposal to include new information in the electronic Database for the Exchange of Type Approval documentation (DETA) and to provide access to this information to new categories of stakeholders. GRE mandated IWG SLR to bring the proposal to IWG DETA for consideration by means of a presentation;
• GRE supported the IWG SLR view on the use of type approval numbers and approval markings for the frozen UN Regulations, i.e. either apply an old number/old marking combination or a new number/new marking combination.
