12. GRE endorsed ECE/TRANS/WP.29/2012/114, introducing the definition of “manufacturer” into UN Regulation No. 48. and withdrew ECE/TRANS/WP.29/2012/115 proposing a similar definition for the Special Resolution (S.R.1), not suitable for self-certification.

13. The expert from the European Commission confirmed his reservations on ECE/TRANS/WP.29/2012/73 and its corr.1 and did not provide further comments to the document.

14. The expert from Germany introduced GRE-68-04 proposing new provisions for the use of light source control gear in the case of halogen incandescent light sources (introduction of a minimum operating voltage). The expert from OICA argued that the proposal could be in contradiction to UN Regulation No. 123 (GRE-68-21). GRE did not support either proposal and agreed to resume consideration of this subject on the basis of a revised proposal, if available.source control gear in the case of halogen incandescent light sources

15. Moreover, GRE resumed discussion on the interpretation of para. 5.9. The expert from GTB made a presentation (GRE-68-36) to introduce a practical demonstration of the variable direction indicator (Variable D.I.) with a variable apparent surface using Light Emitting Diodes (LED). The expert from the Netherlands raised the issue of prioritizing with lighting signals. GTB made a presentation on a research on this issue (GRE-68-37). GRE experts agreed in principle that LED technology has a faster response and flexibility of use that could lead manufactures to puzzling solutions. The expert from GTB informed GRE that work is underway in its Photometry and Signal Lamp task force and gave a verbal progress report. The expert from Spain expressed concerns on the lack of provisions in UN Regulations (i.e. Nos. 6 and 7) dealing with the type approval of components that do not prevent the use of unsafe solutions (concerning variable apparent surface). GRE confirmed the agreement reached on this subject at its March 2012 session (ECE/TRANS/WP.29/GRE/67 para. 58) that according to paragraph 5.9. of UN Regulation No. 48, the installation of a lamp with an intentional variation of the apparent surface would not be allowed and that the same interpretation should be carried over in the type approval of components and technical units (e.g. UN Regulations Nos. 6 and 7.) GRE agreed to resume consideration of this subject at its April 2013 session awaiting outcomes of studies, research and proposals from the expert of GTB.
