Proposal to update document GRE/2016/34. At the 73rd GRE session, France proposed to delete a design restrictive requirement (GRE/2015/22 and GRE-73-26). This proposal received comments from Germany and the Netherlands. Poland suggested a different approach on this issue (GRE-73-21). The Chair invited France, Germany, Netherlands, Poland, CLEPA and IEC to prepare a revised proposal for the next session. Based upon the approach proposed in GRE/2015/22 and GRE-73-26, GTB has investigated the specification of minimum levels of flux projected in critical zones of the passing beam distribution. This approach offers a technology-neutral performance based requirement. The result of the GTB study is to propose minimum projected flux requirements in two zones:
a) 15°D-1°U/30°L-30°R to ensure overall adequate illumination of the road and
b) 3.5°D-1°U/30°L-30°R to ensure sufficient range.

Editorial improvements to the proposal for Supplement 8 to the 01 series of amendments to UN R123.

Revised proposal (removing the section on UN R48 and incorporating corrections noted in document GRE-76-07) to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required. This collective amendment addresses Regulations Nos. 7, 23, 38, 77, 91 and 119. The proposals concerning UN R48 will be resubmitted for consideration during the 77th GRE session.
