23. The Chair of GRE reported on the results of the seventy-third session of GRE (for details, see ECE/TRANS/WP.29/GRE/73).

50. The representative of France proposed to delete a design restrictive requirement in Regulation No. 48 for auto-levelling of headlamps equipped with any Light Emitting Diodes (LED) light sources (ECE/TRANS/WP.29/GRE/2015/21, ECE/TRANS/WP.29/GRE/73 and WP.29-166-23). The representative explained that, if LED were treated the same way as other lights sources, more LED headlamps would be fitted on new vehicles, and thus improving road safety and reducing CO2 emissions. WP.29 noted that recent studies indicate that the type of light source does not seem to be a major factor of headlamp glare, and that GRE had established an IWG to review all levelling requirements in Regulation No. 48 (para. 25 above). The EU representative stressed that also for this subject OLA should be involved to provide their analysis and preferred option.

19. The World Forum recalled the oral report of the Chair of GRE given during the 166th session (ECE/TRANS/WP.29/1116, paras. 23-25) and approved the report.

34. GRE addressed this issue in conjunction with agenda item 4 (para. 10 above).
