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.
