GRSG-110-06
Draft proposal for Supplement 1 to the 01 series of amendments to UN Regulation No. 121

Proposal to enable the use of alternate colors (per footnote 18 of Table 1 and in line with ISO Standard 2575) for certain lighting tell-tales in order to indicate light source failures in response to the proposals for light failure indicators under UN Regulations Nos. 7, 48 and 87 (GRE/2016/7, GRE/2016/12 and GRE/2016/17) as adopted by GRE. This proposal anticipates use of the same approach in response to plans for additional failure indication requirements for other lighting regulations.

GRE | Session 75 | 5-8 Apr 2016

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.

26. GRE recalled that ECE/TRANS/WP.29/GRE/2016/12 had been discussed and adopted together with ECE/TRANS/WP.29/GRE/2016/7 (see para. 16 above).

43. GRE noted that ECE/TRANS/WP.29/GRE/2016/17 was discussed and adopted together with ECE/TRANS/WP.29/GRE/2016/7 (see para. 16 above).

GRSG | Session 110 | 25-29 Apr 2016

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.

GRSG | Session 117 | 8-11 Oct 2019

55. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2019/17 to use more colours to convey information via existing tell-tales. Upon request by experts from different contracting parties, she explained the principle colour coding, namely “green” for function running, “yellow” for information warning, “red” for danger warning, “white” for information and “blue” for information of high beam.

56. GRSG adopted ECE/TRANS/WP.29/GRSG/2019/17 and requested the secretariat to submit it to WP.29 and AC.1 as draft supplement 04 to the 01 series of amendments to UN Regulation No. 121 for consideration at their March 2020 sessions.
