11. The expert from GTB proposed to introduce a new category ‘D9S’ of light sources with dual-level operation into Regulation No. 99 (ECE/TRANS/WP.29/GRE/2015/2) as well as to amend the testing and approval provisions in Regulation No. 98 to take into account the multi-level aspects of D9S (ECE/TRANS/WP.29/GRE/2015/15).

12. Several experts pointed out that the lower level of operation of D9S provide for the objective luminous flux of 2000  300 lm, thus avoiding the need for headlamps with such light sources to be equipped with cleaning devices and automatic levelling. GRE recalled that, according to paragraph 6.2.9. of Regulation No. 48, these additional requirements only apply to headlamps with lights sources whose objective luminous flux exceeds 2,000 lm without taking into account the tolerances specified on the relevant data sheet. GRE agreed that, in the future, headlamps with any new light sources could only be exempted from these additional requirements if their objective luminous flux, together with any tolerance, is below 2,000 lm. GTB was requested to prepare a respective proposal for amendments to Regulation No. 48.

13. Upon this understanding, GRE adopted the above proposals and requested the secretariat to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2015 sessions as draft Supplement 11 to the original series of Regulation No. 99 and draft Supplement 7 to the 01 series of amendments to Regulation No. 98, respectively.
