15. The expert from France introduced a revised amendment proposal on work lamps (ECE/TRANS/WP.29/GRE/2024/12/Rev.1, GRE-92-11-Rev.2). GRE experts commented on the colour of work lamps, vehicle categories, speed limits/thresholds for activation/deactivation and the footnote that national regulations could prohibit the presence of work lamps. For the latter, some experts pointed out that such a footnote might be seen as contradictory to the principle of mutual recognition of type approvals, being a cornerstone of the 1958 Agreement. Following an in-depth discussion, GRE agreed to postpone the discussion to the next session and invited experts, who made comments, to submit their suggestions to France.

15. The expert from France presented a revised proposal on optional work lamps (ECE/TRANS/WP.29/GRE/2024/12/Rev.2, GRE-93-28-Rev.1). He clarified that vehicle categories M1 and N1 were not included in the proposal and that national regulations remained applicable. The expert from OICA provided arguments why, in his view, this proposal should be made in the form of a new series of amendments with transitional provisions. He also pointed out a link to the “prohibited if not allowed” discussion (see para. 8 above). The secretariat recalled that a supplement could also be accompanied with a transitional provision.

16. The experts from Japan, while not in a position to comment on the provisions for unadopted categories, reserved their position regarding this proposal and noted the following two points of concern:

• Though originally intended to be deleted, allowing the work lamp to automatically activate again at 10 km/h was not appropriate.
• The possibility that works lamp could illuminate white light to the backward contradicts the fundamental requirement of UN Regulation No. 48 establishing rear red light.

18. GRE continued consideration of work lamps based on a new document from France (GRE-94-25-Rev.2) and comments from OICA (GRE-94-45). The expert from Japan reiterated their position expressed at the previous session of GRE (ECE/TRANS/WP.29/GRE/94, para. 16). As a result of in-depth discussions, GRE adopted this proposal and agreed to incorporate it in the future 10 series of amendments to UN Regulation No. 48.
