25. The expert from Germany presented ECE/TRANS/WP.29/GRE/2013/60 and ECE/TRANS/WP.29/GRE/2013/61, two revised proposals by France and Germany introducing provisions of direction indicators with variable apparent surface. He gave a practical demonstration supporting the proposal. The expert from OICA presented a study supporting the benefits of such systems (GRE-70-16). The expert from France proposed amendments (GRE-70-43) to ECE/TRANS/WP.29/GRE/2013/61, addressing comments received during the session. GRE noted the intention to only allow the principle of variable apparent surface for direction indicators. GRE agreed on and adopted these proposals as amended by Annex V to the session report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2014 sessions as draft Supplement 26 to the 01 series of amendments to UN Regulation No. 6, as draft Supplement 13 to the 04 series of amendments and as draft Supplement 6 to the 05 series of amendments to UN Regulation No. 48.

26. GRE agreed to revisit this item at its next session and consider the prohibition of variable apparent surface direction indicators for a hazard warning signal and may consider its adoption at its next session for the 06 series of amendments to UN Regulation No. 48.

26. GRE considered two proposals introduced by the experts of France and Germany, ECE/TRANS/WP.29/GRE/2013/13 and ECE/TRANS/WP.29/GRE/2013/14, introducing provisions for variations of the apparent surface of direction indicators. The expert from OICA introduced amendments to the proposals (GRE-69-27 and GRE-69-28). Introducing GRE-69-18 and GRE-69-19, the expert from the Netherlands expressed the concern about the lack of signal uniformity that this proposal would create. GRE requested an assessment of impact upon safety relating to direction indicators with variable apparent surface. The majority of experts from Contracting Parties opposed the proposal made by Germany and France but agreed to resume consideration on this issue on the basis of a revised proposal by the experts from France and Germany. GRE agreed to keep GRE-69-17, GRE-69-18 and GRE-69-30 on the agenda of its October 2013 session.

32. Having recalled its deliberations at the previous session (ECE/TRANS/WP.29/GRE/70, paras. 25 and 26) on direction indicators with variable apparent surface, GRE agreed not to prohibit the use of such indicators for a hazard warning signal and decided to extend the adopted proposals (ECE/TRANS/WP.29/GRE/2013/60 as amended at the seventieth GRE session) to the 06 series of amendments to UN Regulation No. 48. The secretariat was mandated to submit them to WP.29 and AC.1 for consideration at their November 2014 sessions as a new Supplement to the 06 series of amendments to UN Regulation No. 48.
