14. The expert from GTB briefed GRE on activities of the GTB Task Force Conformity of Production (GRE-75-15) and its intention to submit a formal document to the next session of GRE with a view to harmonizing the conformity of production provisions of Regulation No. 123 with those of other headlamp Regulations (e.g. No. 112), for the sake of simplification. The experts from France and UK requested GTB to include a solid justification in their future submission.

59. GRE noted that the status reports of the GTB Working Groups were presented under agenda item 4 (paras. 13 and 14 above).

32. The expert from GTB proposed to align the conformity of production procedures in Regulation No. 123 with the other headlamp Regulations and to simplify the AFS test methods and requirements relating to conformity of production (ECE/TRANS/WP.29/GRE/2016/28 and GRE-75-15). Given the significant volume of the proposed amendment, the experts from UK and EC requested more time to study it. GRE invited experts to send their comments to GTB and agreed to revert to the proposal at the next session upon understanding that, if adopted, it would become part of the new front-lighting Regulation.
