37. The representative of GTB introduced ECE/TRANS/WP.29/2012/119 reflecting the new approach for to the UN Regulations on lighting and light-signalling. Taking advantage of the introduction of the Horizontal Reference Document (HRD) under discussion in GRE and the Database for the Exchange of Type Approvals (DETA) being developed by the DETA informal working group, GTB was studying the possibility of reducing the workload of GRE and WP.29. By consolidating several UN Regulations, GRE may be able to focus its work on only 11 UN Regulations instead of 41 to date. WP.29 endorsed the principles proposed by GTB. Following the discussion, WP.29 mandated GRE to move forward and focus on performance-oriented requirements. WP.29 asked GRE to develop a road map, taking into consideration the resources of GRE.
