Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive.

20. The expert from GTB proposed amendments to light source categories L1A/6 and L1B/6 in the Consolidated Resolution on the common specification of light source categories (R.E.5), together with an associated amendment to UN Regulation No. 128 (ECE/TRANS/WP.29/GRE/2019/15, ECE/TRANS/WP.29/GRE/2019/16). GRE adopted both proposals and requested the secretariat to submit them, as appropriate, to WP.29 and AC.1 for consideration at their March 2020 sessions as draft amendment 5 to R.E.5. and Supplement 10 to the original version of UN Regulation No. 128.

21. The expert of the Task Force on Substitutes and Retrofits (TF SR) presented their progress report (GRE-82-17-Rev.2) and sought the consent of GRE for the following activities of TF SR:

• Not include Light Emitting Diode (LED) retrofits in UN Regulation No. 128.
• Make UN Regulation No. 37 performance based and technology neutral by amending its scope to also include other light generating technologies, e.g. LED.
• Allow interchange of light sources in the same category, as approved according to UN Regulation No. 37, independent of the technology used for light generation.

Proposal from the GRE Task Force on Substitutes/Retrofits to introduce requirements for LED substitute light sources.

23. The expert of TF SR proposed introducing requirements for LED substitute light sources into the new UN Regulation No. [149] on Road Illumination Devices (RID) (ECE/TRANS/WP.29/GRE/2019/19). GRE adopted the proposal and recalled its general view on amending the three new simplified UN Regulations with substantially new provisions (see para. 14 above). Therefore, GRE decided to postpone the submission of ECE/TRANS/WP.29/GRE/2019/19 to WP.29 and AC.1 and to include it the future 01 series of amendments to UN Regulation No. [149] .

20. GRE recalled that, at its previous session, it had adopted the requirements for LED substitute light sources for UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2019/19), but had postponed their submission to WP.29 and AC.1 with the intention to include them in the future 01 series of amendments to UN Regulation No. 149.

Proposal to

• clarify paragraph 2.1 with regard to definitions: “All the definitions given in the latest series of amendments to UN Regulation No. 48 in force at the time of application for type approval shall apply, unless otherwise specified in this UN Regulation or in the pertinent installation UN Regulations Nos. 53, 74 and 86.”
• amend the inboard visibility angle for rear position lamps in pairs in the new UN Regulation on Light-Signalling Devices (LSD)
• Use of LED substitute light source(s) is allowed and does not constitute a change of the lamp type. However, lamp performances shall be tested during type approval also with the LED substitute light source. Approval of the lamp using filament light source(s) is a prerequisite for approval of the lamp using LED substitute light source(s).
• Testing with LED substitute light sources is exempted from conformity of production control.
• The technical description shall include notice that the lamp also has to be approved with the LED substitute light source(s) according to UN R128 if the applicant has so determined.
• The approval marking or the Unique Identifier as well as the category or categories of LED substitute light source(s) prescribed, if any, shall be visible.
• The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.
• Introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.

24. GRE recalled that, for UN Regulation No. [148], the new provisions on substitute light sources had already been submitted to the November 2019 sessions of WP.29 and AC.1 as part of draft Supplement 1 to the original series (ECE/TRANS/WP.29/2019/81). Following the same approach, GRE agreed that these provisions should be removed from the original series of UN Regulation No. [148], once the 01 series of amendments is established.

69. The World Forum considered the draft amendments under agenda items 4.6.1 to 4.6.15 and recommended their submission to AC.1 for voting, subject to the following modifications:

• Item 4.6.3, document ECE/TRANS/WP.29/2019/81, last page, Table A2-1, line “Rear position pair (MR)”, replace “15°/15°” with “15°/10°”.
• Item 4.6.5, document ECE/TRANS/WP.29/2019/125, amend the title to read “Supplement 1 to the original series of UN Regulation No. [149] on Road Illumination Devices (RID)”.

25. GRE addressed a proposal by the expert of TF SR that introduced a new LED substitute light source category H11/LED in R.E.5 (ECE/TRANS/WP.29/GRE/2019/21, GRE-82-03 and GRE-82-12). The experts from France and the United Kingdom expressed concerns about the thermal behaviour of this category. The expert from IEC provided additional explanations (GRE-82-45). Nevertheless, GRE requested TF SR to address the raised issues at its next session on 10 December 2019 and invited all concerned experts to take part in the meeting.
