21. The expert from Germany presented GRE-71-25 introducing flashing side marker lamps for vehicles of categories N2, N3, O3 and O4, aimed at informing vulnerable road users about the intention of a heavy goods vehicle to make a turn. The experts from Italy, Netherlands and CLEPA delivered a number of comments, in particular suggesting the extension of this proposal to M2 and M3 buses. The expert from Germany volunteered to submit a revised official document for the next session of GRE.

16. The secretariat proposed a correction to para. 6.2.7.6.1. of Revision 8 of UN Regulation No. 48 (GRE-71-03). The Chair also proposed the replacement in para. 6.6.7.2. of the incorrect reference to para. 6.22. by para. 6.23. GRE adopted the proposal amended by the Chair and decided to defer the submission of this proposal to WP.29 and AC.1 awaiting the adoption of further corrections that the expert from Italy volunteered to prepare (see para. 17 below).

17. The expert from Italy informed the GRE that he had found a number of errors in Regulation No. 48. GRE invited the expert from Italy to submit a document for the next session (see para. 16 above).

18. GRE noted that the Working Party on General Safety Provisions (GRSG), at its forthcoming session in May 2014, would consider ECE/TRANS/WP.29/GRSG/2014/3 by Germany proposing to insert into UN Regulation No. 107 (M 2 and M 3 buses) a new requirement to automatically activate hazard warning lights when excess temperature is detected in a rear engine and/or in a heater compartment. The Chair expressed his concern that this signal may be misused unnecessarily in case of heat excess not leading to fire. GRE noted that the right term should be “hazard warning signal”. Should this proposal be adopted by GRSG, UN Regulation No. 48 would have to be amended accordingly. Thus, GRE decided to await the outcome of discussion in GRSG and to revert to this issue at the next session on the basis of a proposal for amending UN Regulation No. 48 which the expert from Germany volunteered to submit.

19. The expert from France introduced GRE-71-18 proposing two amendments to series 04 and 05 series of amendments to UN Regulation No. 48:

1. The first amendment introduced interdependent lamp systems in para. 5.18.4. (b) and was based on ECE/TRANS/WP.29/2014/21 adopted during March 2014 session as a new supplement for 06 series of amendments to UN Regulation No. 48.
2. The second amendment suggested that the speed limit in paragraph 6.22.7.4.3 was reduced from 70 to 60 km/h and the requirements of paragraph 6.22.7.4.3(a) was amended to indicate a clear alternative to either detect the motorway conditions with sensors or only activate the E mode above a speed of 110 km/h. The objective of this amendment proposal was to improve the performance of the system by avoiding unnecessary on-off activation of the motorway light. 20. GRE adopted proposal (a) above and requested the secretariat to transmit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft supplement to the 04 and 05 series of amendments to UN Regulation No. 48. GRE decided to come back to proposal (b) at its next session.

22. The expert from OICA introduced GRE-71-29 proposing the simultaneous lightning of both cornering lamps for slow manoeuvres in forward motion, in order to increase safety. GRE requested the secretariat to distribute this proposal at the next session with an official symbol.
