10. Regulation No. 121 (Identification of controls, tell-tales and indicators)

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.

No.	Column 1	Column 2	Column 3	Column 4	Column 5
No.	Item	Symbol ²	Function	Illumination	Colour
1.	Master lighting switch Tell-tale may not act as the tell-tale for the position (side) lamps	^{1, 18}	Control	No
1.		^{1, 18}	Tell-tale ¹²	Yes	Green

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.
