21. The World Forum recalled the oral report of the Chair of GRE, given during the 151st session (ECE/TRANS/WP.29/1085, paras. 24 to 27), and approved the report.

24. The Chair of GRE reported on the results of the sixty-third session of GRE (for details, see the report of the session ECE/TRANS/WP.29/GRE/63).

25. Regarding the 1998 Agreement, he reported that although many lighting and light-signalling devices were designed to be installed on vehicles around the world, GRE had not received any proposals for the development of a gtr in the area of lighting and light-signalling.

26. With regard to the 1958 Agreement, he informed that GRE had agreed to establish an informal group to work on the proposal of a new Horizontal Regulation for light-signalling devices that would contain all common administrative, testing and possibly certain performance provisions existing in individual Regulations. The World Forum endorsed the establishment of such an informal group.

27. Moreover, he reported that GRE had also agreed to set up an informal group to identify conflicting provisions between UNECE Regulations and the 1968 Vienna Convention. He added that the group would focus on recent amendments introducing new innovative safety related technologies in lighting and light-signalling and their relation to the Vienna 1968 Convention, specifically article 32 and Annex 5. The World Forum endorsed the setting up of such an informal group.
