GRE adopted this proposal and requested the secretariat to submit it to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments to Regulation No. 48. The expert from France corrected the French text of the adopted amendment (Annex IX).

24. The expert from OICA introduced a revised proposal which defined and described the operation of the external status indicator for vehicle alarm systems, alarm systems and immobilizers, as contained in Regulations Nos. 97 and 116 (GRE-77-25-Rev.2). Following an in-depth discussion, GRE adopted this proposal, as contained in Annex X, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments and a draft Supplement 12 to the 05 series of amendments to Regulation No. 48.

25. The expert from GTB proposed correcting errors and discrepancies in the text of the 05 and 06 series of amendments to Regulation No. 48 (GRE-78-05). GRE adopted the proposals, as contained in Annex XI, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments and a draft Supplement 12 to the 05 series of amendments to Regulation No. 48. GRE also requested GTB to verify whether or not these amendments are relevant for the 03 and 04 series of amendments to Regulation No. 48 and to report back to GRE at its next session in October 2018.

26. The experts from the Task Force on Headlamp Switching (TF HS) and from SAE introduced alternative proposals which corrected and clarified the requirements for Daytime Running Lamps (DRL) (ECE/TRANS/WP.29/GRE/2018/20, ECE/TRANS/WP.29/GRE/2018/22 and GRE-79-26). The expert from Japan commented on the proposals (GRE-79-03-Rev.1). Following a brief exchange of views, GRE invited the Co-Chairs of TF HS to prepare a consolidated proposal for consideration at the next session.

28. The experts of Germany and Italy proposed a new series of amendments to Regulation No. 48 to clarify the DRL switching-off conditions and/or light intensity reduction when DRL and front direction indicators were totally or partially reciprocally incorporated and when the distance between them was equal or less than 40 mm (GRE-79-25). The expert from OICA submitted a counter-proposal (GRE-79-30). GRE invited the proponents to prepare a consolidated document for the next session.
