Because the new lighting device regulations (LSD, RRD, and RID) each cover multiple lighting functions (e.g. direction indicators, marker lamps, DRL in the LSD regulation), the potential exists for a change in stringency to impact some, but not all functions within the scope of each regulation. The change index is proposed in order to track the impact on each function and so restrict the need for new type approvals only to those functions impacted by a change in stringency.

Correction to document GRE/2018/35 to effect the deletion of the definitions for “bend lighting”, “H plane”, “sequential activation” and “emergency stop signal” in UN R53 (because identical in UN R48). The deletions were inadvertently omitted in the original proposal.

Request to GRE and the SLR informal group to give consideration to transitional provisions.

Proposal to amend the inboard visibility angle for rear position lamps in pairs.

Proposal from the Simplification of Lighting Regulations informal group to introduce transitional provisions for the phasing out of the existing Regulations on lighting and light-signalling in conjunction with the introduction of three new simplified Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD).

Proposal to align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps.

Recent amendments to the Canada Motor Vehicle Safety Standard (CMVSS) 108 allows UN Regulation
headlamps to be used on vehicles in Canada. CMVSS 108 specifically refers to the existing UN Regulations. In order to continue the acceptance of headlamps compliant with UN Regulations in Canada after the switch to the new Road Illumination Devices (RID) regulation, the current regulations should make clear references to RID before they are frozen and superseded.

Proposal from IWG SLR based on a proposal from the International Motorcycle Manufactures Association (IMMA) to amend the inboard visibility angle for rear position lamps in pairs in the new UN Regulation on Light-Signalling Devices (LSD).

SLR informal group removing the brackets around (i.e., confirming) the 24-month transition period for the switch to approvals only under the new LSD, RRD, and RID regulations and to delete the proposal that approvals and extensions of approvals granted under each regulation would remain valid indefinitely.

Proposal to restore the definition of “device” (because the definition under UN R53 differs from that under UN R48) and to delete the definitions of “bend lighting”, “H plane”, “sequential activation” and “emergency stop signal” (because they are identical to the definitions in UN R48).

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.”

Proposal to specify the use of UN R48 definitions unless otherwise specified in the current regulation or in lighting installation regulations for other vehicles categories (i.e., in UN R53, R74, or R86), to harmonize the Conformity of Production (CoP) provisions regarding the permitted re-aim angles for class A and B headlamps, and to harmonize Class C passing beam values. The SLR informal group intends for these changes, if approved, to be considered by WP.29 at its November 2018 session along with the original RID proposal (WP.29/2018/158).

Proposal from the SLR informal group to improve the text of the draft new UN Regulation on retro-reflecting devices (RRD). The proposal adds that the definitions in UN R48 apply unless the regulation or the vehicle-category-specific regulations (UN R53, 78, 86) specify different applicable definitions, to clarify that the construction provision and prohibition on use of paints or varnishes under paragraph 4.1.6 only apply to retro-reflectors, to correct the omission of Class F devices from the title of paragraph 5.4., and to add the water-resistance test (from UN R69 and R70) to Annex 7. The amendments, if approved, are intended to be considered with the original draft of the new Regulation sent to the November 2018 WP.29 for adoption (WP.29/2018/159).

Proposal to introduce the following changes into the draft new Regulation on light-signalling devices:

1. 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).
2. Testing with LED substitute light sources is exempted from conformity of production control.
3. 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.
4. 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.
5. The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.

Proposal from the Special Interest Group on L-category vehicle daytime running lamps to introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.
