GRE | Session 73 | 13-17 Apr 2015

47. At the GRRF request, the secretariat presented the idea of introducing a warning lamp into Regulations Nos. 79 and 13 to light up at any brake application and to indicate the proper functioning of the trailer electrical braking system on some trailers (GRE-73-09). GRE agreed that such lamps do not fall under the scope of Regulation No. 48 and, if required, such an exemption could be introduced explicitly into the definitions of Regulation No. 48.
