Proposal from the Task Force on Tell-Tales for Supplement 17 to the 04 series of amendments, for Supplement 10 to the 05 series of amendments and Supplement 8 to the 06 series of amendments to Regulation No. 48.

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.

The current requirements on light source failure in lamps equipped with multiple light sources differ across UN Regulations. GTB submitted and then withdrew a proposal to align these requirements (GRE/2016/13). This updated proposal improves upon the text of the previous proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

14. The expert of GTB proposed to update the requirements on light source failure in lamps equipped with multiple light sources in Regulations Nos. 7, 23, 38, 48, 77, 91 and 119 (ECE/TRANS/WP.29/GRE/2016/31, GRE-76-07 and GRE-76-22-Rev.1). The proposal received comments from the experts of Italy, UK and OICA. GRE agreed to take out the amendment proposal to Regulation No. 48 and to consider it separately at the next GRE session. GRE adopted the remaining proposals, as amended by Annex II to the report, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2017 sessions as part of the consolidated amendment proposals (see para. 10 above).
