13. The experts from GTB proposed several amendments that aligned the requirements in UN Regulation No. 48 with the updated requirements in UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2024/3), that aligned the requirements for the passing-beam vertical inclination for off-road vehicles between the 06, 07, 08 series and the 09 series of amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/4) and that avoided exceeding the aggregate maximum intensity of the main-beam headlamps (ECE/TRANS/WP.29/GRE/2024/5 as replaced by GRE-90-10). GRE adopted these proposals in principle and decided to postpone their submission to WP.29 and AC.1, in order to combine them in the future with other amendment proposals to the same series of amendments.

14. The expert from the Task Force on Lamps Under Parked Conditions (TF LUPC) reported on their activities (GRE-90-18) and presented a proposal for the TF LUPC Terms of Reference and rules of procedure (GRE-90-03). GRE adopted the proposal upon understanding that this decision should not be regarded as a precedent for requiring all task forces in the future to establish their terms of reference.

15. The expert from France recalled the discussion on work lamps at the previous session and introduced draft amendments (GRE-90-26). Following a brief exchange of views, GRE invited experts to provide their comments to France and to continue consideration at the next session on the basis of an official document.

16. GRE recalled its earlier discussion on the perceived blueish colour of the white light emitted by front lighting units (GRE-89-24) and noted that the expert from France would submit a proposal for consideration at the next session.

17. The expert from Norway requested a guidance on the interpretation of paragraph 5.22. of UN Regulation No. 48 on lamps that are deemed not to be present (GRE-90-14). The Chair of IWG SLR recalled their status report and list of future activities (GRE-90-08) which included clarification on this and related issues in UN Regulations Nos. 48, 53 and 74, based on the principle “prohibited if not allowed” for the lamp installation. Some experts pointed out that the main purpose of paragraph 5.22. was not to leave holes in the car body in case a specific lamp (e.g. left/right rear fog lamp) was not used, for instance, for the right/left hand traffic.

18. The expert from China identified possible inconsistencies in the 08 series of amendments to UN Regulation No. 48 (GRE-90-30). Following a brief exchange of views, the Chair invited the expert to draft amendment proposals for consideration at the next session. The expert from EC pointed out that they would not react to the future proposals from China, as coming from the country which is not a contracting party to the 1958 Agreement.

19. The expert from OICA proposed to remove the current restriction in paragraph 6.12.1. that prohibits the fitment of parking lamps to vehicles which exceed 2 m in width (GRE-90-22). Several experts supported the proposal and further pointed out the need to also remove the length restriction of 6 m in the same paragraph. GRE realized that these two restrictions had originated in the 1968 Vienna Convention on Road Traffic, and invited OICA to update their proposal for consideration at the next session.
