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.

The collective amendment presented in GRE/2016/34 extends the usage of LED light sources of UN R128 to front lighting Regulations Nos. 19, 98, 112, 113 and 123. The introduction of LED light source categories under UN R128 for forward lighting applications (front fog, low beam, high beam,
AFS) is planned for 2017. This presentation explains the plans, timeline, and dependencies GTB proposes to address through the collective amendment, especially within the context of the simplification of lighting regulations program.

Analysis raising concerns regarding the proposal to establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) without reference to design specifications such as the luminous flux of light source.
