31. The expert from Canada recalled ECE/TRANS/WP.29/GRSG/2010/20 proposing the addition of more symbols in Regulation No. 121. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2011/6 and GRSG-100-10 commenting on ECE/TRANS/WP.29/GRSG/2010/20. Noting that the input from other Working Parties on this proposal was needed, GRSG invited the expert from Canada to present this proposal to the Working Party on Brakes and Running Gear (GRRF) and Working Party on Lighting and Light-Signalling (GRE). GRSG agreed to consider the matter at its October 2011 session together with the feedback from GRE and GRRF. GRSG requested the secretariat to merge ECE/TRANS/WP.29/GRSG/2011/6 and GRSG-100-10 for consideration at its October 2011 session.

32. GRSG considered ECE/TRANS/WP.29/GRSG/2011/7 by OICA on the parking brake tell-tale. GRSG agreed to reconsider again this item at its October 2011 following the detailed consideration of ECE/TRANS/WP.29/GRSG/2011/7 by GRRF at its September 2011 session.

33. The expert from Canada presented ECE/TRANS/WP.29/GRSG/2011/8 and GRSG-100-14 clarifying the text of Regulation No. 121 and aligning the terminology used for passing and driving beams in lighting Regulations. The expert from OICA pointed out that the terminology used throughout Regulation No. 48 should also be made more consistent. GRSG adopted ECE/TRANS/WP.29/GRSG/2011/8, as amended by GRSG-100-14 reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2011 session, as draft Supplement 6 to Regulation No. 121.

Paragraph 2.5., amend to read:

• “2.5. ”Tell-tale" means an optical signal that, when alight, indicates the actuation or deactivation of a device, a correct or defective functioning or condition, or a failure to function."
