17. The expert from GTB presented revised amendments to Regulation No. 128 and to R.E.5 which introduced requirements, test specifications and new categories for light emitting diode (LED) substitute light sources (ECE/TRANS/WP.29/GRE/2017/17, ECE/TRANS/WP.29/GRE/2017/21). The proposals also included collective amendments to Regulations Nos. 48, 53, 74, 86 (ECE/TRANS/WP.29/GRE/2017/22 and GRE-78-02). The experts from Italy and OICA submitted written comments on the proposals (GRE-78-33 and GRE-78-28).

18. GRE noted that, compared to the original GTB proposals that had been considered at the previous session, the revised proposals contained safeguards against the possible misuse of LED substitutes as retrofits in lamps and/or vehicles that were not type approved for using such light sources. A number of experts were of the view that the proposed measures, such as consumer warning on packaging and a website with a list of compatible vehicle models, were not sufficient and reiterated their concerns as raised at the previous session. The expert of OICA pointed out that, to avoid any responsibility for misusing LED substitutes when installing on old vehicle types, the vehicle manufacturers would have be burdened to extend type approvals pursuant to the earlier series of amendments to Regulation No. 48 (GRE-78-28). GRE acknowledged the problem and noted that the failure detection provisions in Regulation No. 48 should be revised. Some experts advocated the idea of physical keying of LED caps to prevent installing unauthorized substitutes.

19. GRE noted that the discussion addressed two different, but interrelated issues: (a) allowing LED substitutes for new type approvals, as part of Original Equipment Manufacturer (OEM) and Original Equipment Supplier (OES), and (b) using LED as retrofits on old vehicle types. Some experts were of the view that the two cannot be separated from one another. To make progress, GRE agreed to establish a task force. The expert from Germany stated that another expert from his country would act as Chair of the task force, while the expert from UK provisionally agreed to become Co-Chair. The expert from IEC volunteered to provide secretarial support.

101. The representative of Belgium, Chair of the Working Party on Lighting and Light-Signalling (GRE), presented to the World Forum for consideration the proposals for amendments 1 and 2 to the Consolidated Resolution on the common specification of light source categories (R.E.5) (ECE/TRANS/WP.29/2018/32 and ECE/TRANS/WP.29/2018/33/Rev.1).

102. WP.29 adopted ECE/TRANS/WP.29/2018/32 and ECE/TRANS/WP.29/2018/33/Rev.1 without objections or abstentions. WP.29 noted that Amendment 2 to R.E.5 (ECE/TRANS/WP.29/2018/33/Rev.1) should be made public on the same date as the entry into force of Supplement 7 to the original version of UN Regulation No. 128 (ECE/TRANS/WP.29/2018/30).

102. WP.29 adopted ECE/TRANS/WP.29/2018/32 and ECE/TRANS/WP.29/2018/33/Rev.1 without objections or abstentions. WP.29 noted that Amendment 2 to R.E.5 (ECE/TRANS/WP.29/2018/33/Rev.1) should be made public on the same date as the entry into force of Supplement 7 to the original version of UN Regulation No. 128 (ECE/TRANS/WP.29/2018/30).

17. On behalf of TF SR, the expert from Germany introduced amendment proposals to UN Regulation No. 128 for the use of LED substitute light sources (ECE/TRANS/WP.29/GRE/2018/39) as well as corresponding amendments to the Consolidated Resolution on the common specification of light source categories (R.E.5) (ECE/TRANS/WP.29/GRE/2018/40). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 9 to the original version of UN Regulation No. 128 and as draft amendment 3 to R.E.5. GRE noted that both amendments are part of the same package and should enter into force on the same date.

115. The World Forum adopted the proposal and noted that it constitutes a package and should enter into force on the same date with draft Supplement 9 to the original version of UN Regulation No. 128 (LED light sources) (ECE/TRANS/WP.29/2019/19, agenda item 4.9.3).

14. The expert from the Task Force on Substitutes and Retrofits (TF SR) proposed editorial corrections and further modifications to ECE/TRANS/WP.29/GRE/2018/40, which had been adopted at the previous session of GRE and in which the information for the 24V version was missing (GRE-81-06). GRE adopted the proposal, as contained in Annex III, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2019 sessions as part of the draft amendment to R.E.5 mentioned in paragraph 13 above.
