5. | UN Regulations Nos. 37 (Filament lamps), 99 (Gas discharge light sources), 128 (Light emitting diodes light sources) and the Consolidated Resolution on the common specification of light source categories)

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.

5. | Regulations Nos. 37, 99, 128 and RE5 (light-source specifications)

20. The expert from GTB presented revised proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) with the aim to introduce requirements, test specifications and a new category for forward lighting LED light sources (ECE/TRANS/WP.29/GRE/2017/16, ECE/TRANS/WP.29/GRE/2017/20). GRE adopted the amendments and requested the secretariat to submit them to WP.29 and to AC.1 (Regulation No. 128 only) for consideration and vote at their March 2018 sessions. GRE noted that, if adopted, the R.E.5 amendment would enter into force on the same day as the corresponding supplement to Regulation No. 128.

5. | Regulations Nos. 37, 99, 128 and RE5

15. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) that introduce a new LED light source category for forward lighting applications (ECE/TRANS/WP.29/GRE/2017/5, ECE/TRANS/WP.29/GRE/2017/6, GRE-77-04, GRE-77-12, GRE-77-13). He explained that GTB had abandoned the concept of “thermal grade” and instead proposed the introduction of a maximum test temperature to ensure interchangeability between approved light sources from different manufacturers. GRE also noted the proposal by GTB to incorporate LED light sources into the new RID Regulation (GRE-77-14).

16. The expert from UK requested more time to study the proposals. The expert of Germany proposed modifications to the notion of “maximum test temperature”. GRE decided to revert to this issue at the next session and invited GRE experts to study the proposals and to send their comments to GTB and IWG SLR.
