| Summary | Proposal to delete footnote 18 of Table 1 regarding telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). The footnote is redundant and potentially confusing since UN R121 already refers to paragraph 5. of ISO 2575-2004 which states, "A given symbol may be shown in more than one of the colours specified in 5.1 in order to convey a change in the operating condition." | ||||||||||||||||||||||||||||

49. The expert from OICA presented ECE/TRANS/WP.29/GRSG/2017/18 to clarify footnote 18 where tell-tales Nos. 1 and 19 were combined. Some experts were of the opinion that footnote 12 already offers that possibility. Following the discussion, the expert from OICA offered an alternative proposal GRSG-113-39 that simplifies the handling of colour changes of tell-tales and to remove footnote 18 and all references to it. The expert from France preferred to keep the existing text of footnote 18 and to only insert under symbol No. 1 a reference to footnote 18, as reflected in GRSG-113-42. GRSG agreed to go forward with a two-step approach and adopted ECE/TRANS/WP.29/GRSG/2017/18 as reproduced below.
50. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft Supplement 10 to the original series of amendments and Supplement 3 to the 01 series of amendments to UN Regulation No. 121 for consideration at their March 2018 sessions, subject to the endorsement of the Working Party on Lighting and Light Signalling (GRE) at its October 2017 session. (Note by the secretariat: At its seventy-eighth session, GRE endorsed the principles for amending UN Regulation No. 121 as proposed by GRSG.) 51. As a second step, GRSG requested the secretariat to distribute GRSG-113-39 with an official symbol, for consideration at the next GRSG session and to also circulate it all WP.29 Working Parties concerned. |
