20. The expert from GTB proposed to clarify the requirements for tell-tales indicating a failure of different lamps (GRE-77-16). The expert from OICA introduced a proposal to update paragraph 6.9.8. with the common current technologies, where the instrument panel remains permanently illuminated whenever the engine is running (GRE-77-20). The experts from Italy, Netherlands and UK indicated their support to GRE-77-16, but were of the view that the wording in GRE-77-20 would need improvement. The experts of Germany and SAE pointed out that both proposals had a link to Regulation No. 121 and that the Working Party on General Safety (GRSG), dealing with this Regulation, should be informed. Finally, GRE invited GTB and OICA to take account of the above comments and to submit an official document to the next session.

45. GRSG noted the outcome of the recent session of GRE (GRSG-110-04) and the request to align UN Regulation No. 121. In this respect, the expert from Italy presented GRSG-110-06 aimed at clarifying the provisions of UN Regulation No. 121 with respect to the indication of the failure of a light source.

46. GRSG adopted the proposal as reproduced in Annex IV to this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplement 9 to the original version of UN Regulation No. 121 and as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 121.

16. The expert from the Netherlands, in his capacity of Chair of the Task Force on Tell-Tales (TF TT), introduced revised proposals for amendments to Regulations Nos. 48, 7 and 87 on tell-tales which indicate a failure (ECE/TRANS/WP.29/GRE/2016/7, ECE/TRANS/WP.29/GRE/2016/12 and ECE/TRANS/WP.29/GRE/2016/17). GRE adopted the proposals and decided to submit them to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 17 to the 04 series of amendments, draft Supplement 10 to the 05 series of amendments and draft Supplement 8 to the 06 series of amendments to Regulation No. 48, draft Supplement 25 to the 02 series of amendments to Regulation No. 7 and draft Supplement 18 to Regulation No. 87.

17. Several experts pointed out that the adopted amendments might also require an amendment to paragraph 5.4. of Regulation No. 121 (Identification of controls, tell-tales and indicators), but no consensus was reached on this issue. GRE invited the Working Party on General Safety Provisions (GRSG), which deals with Regulation No. 121, to address this matter.

50. On behalf of the Task Force on Tell-Tales, the expert from the Netherlands proposed amendments to Regulations Nos. 7, 87 and 48 regarding tell-tales indicating a failure (GRE-73-11). To prepare an official document for the next session, he invited GRE experts to send their comments by email.
