GRE will be informed about the progress of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR).

GRE will address IWG SLR proposals for amendments to UN Regulation No. 48 that corrects a reference to UN Regulation No. 148.

GRE is also invited to consider IWG SLR proposals that clarify and correct the text of various series of amendments to UN Regulation Nos. 148, 149 and 150.

At its previous session, GRE reviewed UN Regulations under its purview for the purposes of the Unique Identifier (UI) (GRE-88-26) and classified them as follows:

1. Obsolete device UN Regulations that had been frozen in the course of two freezing exercises;
2. New simplified device UN Regulations Nos. 148, 149 and 150;
3. Installation UN Regulations Nos. 48, 53, 74 and 86;
4. Light sources UN Regulations Nos. 37, 99 and 128; and
5. Standalone UN Regulations Nos. 10, 45 and 65.

GRE agreed that UI could be used for the group (b) above, but definitely not for (a) and probably not for (c) and (d). GRE decided to revert to this topic at this session, including the issue of additional markings.
