Working Party on Lighting and Light-signalling | Session 74 | 20-23 Oct 2015

30. The expert from IMMA introduced a proposal allowing for the use of different brake lamp activation methods and aligning the brake lamp provision with those applicable for four-wheelers (ECE/TRANS/WP.29/GRE/2015/42). The experts of France, Germany, Italy and Japan delivered remarks. GRE noted that this proposal might need to be accompanied by a modification of Regulation No. 78 under the responsibility of the Working Party on Braking and Running Gear (GRRF). IMMA was invited to contact GRRF and to present an updated document for the next session.

21. The expert from IMMA introduced ECE/TRANS/WP.29/GRRF/2017/14 as amended GRRF-84-13 with provisions allowing additional conditions for the activation of the stop lamp. The expert from Canada recommended addressing this question within GTR No. 3. The Chair noted that ETRTO would not be allowed to propose amendments to GTR No. 3 and asked whether a Contracting Party to the 1998 Agreement could sponsor this amendment. GRRF raised the question why the author of the proposal selected provisions from Regulation No. 13 and not from Regulation No. 13-H. The expert from IMMA agreed to submit a revised proposal for the February 2018 session of GRRF.
