25. The expert from IWG SLR proposed several corrections (ECE/TRANS/WP.29/GRE/2020/24 and GRE-83-06). GRE adopted these proposals and requested the secretariat to submit them for consideration and vote at the March 2021 sessions of WP.29 and AC.1 as draft Supplement 14 to the 06 series of amendments and draft Supplement 1 to the 07 series of amendments to UN Regulation No. 48.

GRE-83-06 | UN R48: Proposal for a Supplement For light sources with integrated electronics an "Electronic light source control gear" comprises components between the supply and the light emitting elements. The definition was derived from IEC and CIE, where a light source is the light emitting element. Provisions for "Electronic light source control gear" are normally used in installation and device regulations, but create confusion in relation to light sources with integrated electronics. Therefore, it is proposed to tune this term to the use in installation and device regulations and no longer specifically mention integration (or not) in the light source; "Electronic light source control gear" is not defined in R.E.5., but is part of the light source definition. The proposal also delete the term "igniter" because it is not used in the regulation.

GRE/2020/24 | UN R48: Proposal for a corrigendum to the 06 and 07 series of amendments Proposal from the SLR informal group to correct paragraph numbering and to re-introduce omissions that were deleted by mistake by previous amendments.

26. The expert of IWG SLR introduced draft amendments to references in UN Regulation No. 48, anticipating the future 01 series of amendments to UN Regulation No. 149 (GRE-83-22 and GRE-83-23).

GRE-83-22 | UN R48: Proposal for a Supplement to the 06 and 07 series of amendments Proposal from the SLR informal group to introduce into the 06 and 07 series of amendments to UN R48 references to the headlamp Classes in the 01 series of amendments to UN R149.

GRE-83-23 | UN R48: Proposal for a Supplement to the 03, 04, and 05 series of amendments Proposal from the SLR informal group to introduce into the 03, 04, and 05 series of amendments to UN R48 references to the headlamp Classes in the 01 series of amendments to UN R149.

27. GRE took note of GRE-83-29 and GRE-83-42 and requested their submission as official documents to the next session. GRE also took note that an updated proposal for the sun load impact would be submitted to the next session (GRE-83-40).

GRE-83-29 | UN R48: Proposal for amendments Proposal to permit the installation of manoeuvring lamps on trailers.

GRE-83-40 | Update concerning sun-load impact on light-signalling devices proposal

GRE-83-42 | UN R48: Proposal for a Supplement Proposal to address semitrailers where the required distance of the foremost side-marker lamp of 3 m from the front cannot be achieved.

29. Based on a proposal of IWG SLR, GRE continued its deliberations for preparing a new series of amendments to UN Regulation No. 48 with new requirements for headlamp aiming and automatic levelling (ECE/TRANS/WP.29/GRE/2020/8/Rev.1). The expert from Poland held the view that the justification part contained mistakes and inconsistencies and recalled his earlier proposals on the subject (GRE-83-41). Several experts expressed their support to the IWG SLR proposal.

30. The expert from OICA proposed to keep an option of manual levelling (ECE/TRANS/WP.29/GRE/2020/23 and GRE-83-31). Some experts supported this option, while others were not in favour.

31. In the absence of a consensus, GRE stressed the need to finalize the issue as soon as possible and requested IWG SLR to take into account the comments made and to prepare a revised working document for the next session, based on the following principles:

• the aiming diagram agreed at the eighty-first session of GRE (Annex II to ECE/TRANS/ WP.29/GRE/81);
• automatic levelling;
• manual levelling, only if a consensus is reached within IWG SLR.

32. The expert from Poland did not agree to that conclusion.

33. GRE instructed IWG SLR to organize a separate meeting on this issue and encouraged all experts of Contracting Parties to participate.

GRE-83-31 | UN R48: Revised proposal for a new [0x] series of amendments For a more efficient discussion during the 83rd session of GRE the experts from the International Organization of Motor Vehicle Manufacturers merged documents GRE/2020/08-Rev.1 (SLR) and GRE/2020/23 into one document.

35. GRE noted GRE-83-45 submitted by the experts from Japan and invited them to submit an official document to the next session. In the interim, the Chair suggested that IWG SLR should also consider this proposal.

GRE-83-45 | UN R48: Proposal for a new series of amendments Proposal to minimize hazards to other traffic users such as glare and distraction by expanding the scope of the vehicle’s conditions subject to technical requirements under "normal conditions of use" (para. 5.1.), including use of lighting when parked or engine stopped.

36. The expert from IMMA introduced a proposal that allowed the installation of adaptive driving beam (ADB) on vehicles of category L3 (ECE/TRANS/WP.29/GRE/2020/13/Rev.1, as amended by GRE-83-51). This proposal was submitted in a package with amendment proposals to UN Regulation No. 149. GRE adopted these proposals as draft Supplements to the 01, 02 and 03 series of amendments to UN Regulation No. 53 and to the original series of amendments to UN Regulation No. 149. GRE agreed to postpone their submission to WP.29 and AC.1 pending the future 01 series of amendments to UN Regulation No. 149.

37. GRE considered a proposal by the expert from IWG SLR that corrected references to definitions in the body of UN Regulation No. 53 (ECE/TRANS/WP.29/GRE/2020/19). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2021 sessions of WP.29 and AC.1 as draft Supplement 4 to the 02 series of amendments and draft Supplement 1 to the 03 series of amendments to UN Regulation No. 53.
