UN R149: Proposal for Supplement 2
Status: Adopted

Proposal to reintroduce the run-up provisions for high-intensity discharge (HID) headlamps that were unintentionally omitted from the original text of UN R149.

Discussions and Outcomes
85th GRE session (26-29 Oct 2021)
GRE/2021/14

12. The expert from IWG SLR introduced a proposal for a new series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2021/14, GRE-85-04 and GRE-85-14). The expert from IEC proposed updating the references to standard IEC 60809 (GRE-85-09). GRE adopted ECE/TRANS/WP.29/GRE/2021/14, as amended by GRE-85-09 and GRE-85-14, and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as draft 01 series of amendments to UN Regulation No. 149.

13. For reasons mentioned at the previous session (GRE-84-28), the expert from Poland was not in a position to support the IWG SLR proposal. GRE also recalled the alternative transitional provision in GRE-85-30 and requested IWG SLR to consider it and to report back to GRE at its next session in April 2022 (see paragraph 10 above).

14. The expert from Germany wondered if it would be acceptable to drive, for a limited time, with one headlamp (passing beam) of the matched pair, as defined in paragraph 4.18. of ECE/TRANS/WP.29/GRE/2021/14. He recalled that, under the current requirements for periodical technical inspections in the European Union (e.g. paragraph. 4.1.1 (a) of directive 2014/45/EU), a non-working headlamp was a minor defect which would not impede passing the inspection. He added that footnote (a) to paragraph 5.2.2. in ECE/TRANS/WP.29/GRE/2021/14 might lead to an expectation that, in the worst-case scenario with one remaining headlamp of the matched pair, only 50 per cent of luminous intensity would be reached in some elements instead of 100 per cent for one headlamp. According to the expert, this could affect the assessment of roadside inspections and periodical technical inspections. GRE requested IWG SLR to address the question raised by the expert from Germany.

27. GRE stressed that the adopted amendments to UN Regulations Nos. 48, 53, 74, 86, 148, 149 and 150, as reflected in paragraphs 9, 12, 15, 17, 20, 23–26, 31 and 33, should be submitted as a package to the June 2022 sessions of WP.29 and AC.1. GRE agreed to review these proposals at its next session in April 2022.

180th WP.29 session (9-12 Mar 2020)
This proposal (WP.29/2020/33) was adopted by the World Forum. Thirty-nine Contracting Parties out of the 55 applying UN R149 were present for the vote by AC.1. Thirty-nine voted in favor with zero against and zero abstaining.
82nd GRE session (22-25 Oct 2019)
GRE/2019/24

9. The expert from IWG SLR introduced corrections of mistakes and omissions in the text of the new UN Regulations Nos. [148], [149] and [150] (ECE/TRANS/WP.29/GRE/2019/24, ECE/TRANS/WP.29/GRE/2019/25 and ECE/TRANS/WP.29/GRE/2019/26). GRE adopted the corrections and mandated the secretariat to submit them to WP.29 and the Administrative Committee (AC.1) for consideration at their March 2020 sessions. GRE also requested the secretariat to verify with the United Nations Office for Legal Affairs (OLA) whether the adopted corrections could be introduced in the form of corrigenda to the original versions of the three new UN Regulations.
