Working Party on Lighting and Light-signalling | Session 85 | 26-29 Oct 2021
Geneva
Agenda Item 4. (c)
UN Regulation No. 149 (Road illumination devices)

11. GRE considered clarifications and corrections that were prepared by IWG SLR (ECE/TRANS/WP.29/GRE/2021/12). GRE adopted the document and requested the secretariat to submit it for consideration and vote at the March 2022 sessions of WP.29 and AC.1 as draft Supplement 5 to the original series of amendments to UN Regulation No. 149.

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.
