GRE-79-15 | General information and WP.29 highlights for the 79th GRE session

5. Mr. W. Nissler, WP.29 Secretary and Chief, Vehicle Regulations and Transport Innovations Section, reported on the main results of the February 2018 session of the Inland Transport Committee (ITC) and of the March 2018 session of WP.29. He also briefed GRE on Resolution A/RES/72/271 “Improving global road safety” adopted on 12 April 2018 by the General Assembly of the United Nations as well as on the launch of the United Nations Road Safety Trust Fund.

2. 1998 Agreement - Global Technical Regulations: Development

6. The expert from GTB pointed out the growing interest in global harmonization of lighting and light-signalling norms, in particular in China and the United States of America. According to him, stage 2 of the ongoing process for Simplification of the Lighting and Light-signalling Regulations (SLR), which focused on technology-neutral requirements, could pave the way to developing of a new Global Technical Regulation (GTR). He also identified light-signalling functions of autonomous vehicles as a possible topic for a new GTR. The experts from the Netherlands, UK, EC, OICA and SAE supported this idea. The expert from the United States of America encouraged all stakeholders to start a dialogue on this issue.

3. 1997 Agreement – Rules: Development

7. No information was reported under this agenda item.

4. Simplification of lighting and light-signalling Regulations

8. On behalf of the Informal Working Group on Simplification of the Lighting and Light-Signalling Regulations (IWG SLR), the expert from GTB reported on the finalization of stage 1 of SLR (GRE-79-28). He further provided a draft schedule for stage 2 which would include two steps. Step 1 would cover objectives which could be achieved by the end of 2019, such as introducing technology neutral and performance based requirements, as well as objectively testable provisions. Step 2 would start in 2020 with the aim to simplify the installation Regulations Nos. 48, 53, 74 and 86. As an additional task, he suggested harmonization with the applicable standards in China. GRE experts also proposed other issues for stage 2 of SLR.

9. The expert from GTB presented the full package of amendment proposals drafted by IWG SLR under stage 1 of SLR:

a) The three new simplified UN Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD) (ECE/TRANS/WP.29/GRE/2018/2, ECE/TRANS/WP.29/GRE/2018/3, ECE/TRANS/WP.29/GRE/2018/4, GRE-79-10 and GRE-79-14);

b) Draft amendments to Regulations Nos. 48, 53, 74 and 86 that group the definitions and introduce references to the new simplified Regulations (ECE/TRANS/WP.29/GRE/2018/6, ECE/TRANS/WP.29/GRE/2018/7, ECE/TRANS/WP.29/GRE/2018/8, ECE/TRANS/WP.29/GRE/2018/9, ECE/TRANS/WP.29/GRE/2018/10, ECE/TRANS/WP.29/GRE/2018/12, ECE/TRANS/WP.29/GRE/2018/13, ECE/TRANS/WP.29/GRE/2018/14, ECE/TRANS/WP.29/GRE/2018/15, ECE/TRANS/WP.29/GRE/2018/17, ECE/TRANS/WP.29/GRE/2018/30, GRE-79-08, GRE-79-09 and GRE-79-13);

c) Transitional provisions to “freeze” Regulations Nos. 3, 4, 6, 7, 19, 23, 27, 38, 50, 69, 70, 77, 87, 91, 98, 104, 112, 113, 119 and 123 (ECE/TRANS/WP.29/GRE/2018/11).

10. The expert from EC was not in a position to support the indefinite validity of type approvals granted under the frozen Regulations, as proposed in ECE/TRANS/WP.29/GRE/2018/11, because of the General Safety Regulation of the European Union. He proposed revised transitional provisions for these Regulations (GRE-79-31, part I), together with new transitional provisions for the installation Regulations Nos. 48, 53, 74 and 86 (GRE-79-31, part II). While several experts agreed in principle with part I, they were not in a position to support part II. The experts from Finland and UK made study reservations. The expert from OICA expressed the concern that the revised transitional provisions might be rejected by WP.29.

11. To not delay the submission of the whole package of amendment proposals that had been developed in stage 1 of SLR, GRE decided to provisionally adopt the transitional provisions in ECE/TRANS/WP.29/GRE/2018/11, but to put in square brackets the third transitional provision for each Regulation mentioned in the document. At the same time, GRE recognized the urgency of the issue raised by the expert from EC and requested all GRE experts, as well as IWG SLR, to carefully consider the EC proposals with a view to taking a final position at the next session.

12. The expert from IWG SLR proposed correcting minor errors and inconsistencies identified in the documents mentioned under para. 9 (a) above (GRE-79-14). GRE adopted these corrections, as laid down in Annex II.

13. The expert from IWG SLR also suggested rectifying minor errors and inconsistencies in the documents listed in para. 9 (b) above (GRE-79-13). GRE adopted these corrections, as laid down in Annex III, and decided to opt for the alternative wording (in square brackets) of paragraph 6.3.9. of different series of amendments to Regulation No. 48.

14. The expert from India suggested corrections to ECE/TRANS/WP.29/GRE/2018/2 and ECE/TRANS/WP.29/GRE/2018/3 (GRE-79-17-Rev.1 and GRE-79-18-Rev.1 new text). GRE adopted the corrections, as laid down in Annexes IV and V. The expert from India withdrew GRE-79-19, in order to first present it at the next session of IWG SLR.

15. The expert from IWG SLR recalled that all identical definitions should only be kept in Regulation No. 48. Thus, he proposed to review the definitions in Regulations Nos. 53 and 74 (GRE-79-08 and GRE-79-09, respectively). GRE adopted these modifications, as contained in Annex VI.

16. The expert from IWG SLR presented the concept of “change index” developed for the LSD, RID and RRD Regulations (GRE-79-12-Rev.1). He further introduced amendment proposals on the change index to Regulations Nos. 48, 53, 74 and 86 (ECE/TRANS/WP.29/GRE/2018/16, ECE/TRANS/WP.29/GRE/2018/18 and GRE-79-11). GRE adopted these proposals, as amended by Annex VII). In addition, GRE agreed to include transitional provisions on the change index in the text of the LSD, RID and RRD Regulations (GRE-79-10 and Annex VIII). The expert from India pointed out that he would refer GRE-79-22 to IWG SLR.

17. Subject to the modifications mentioned in paras. 10–16 above, GRE adopted the package of amendment proposals drafted by IWG SLR and listed in para. 9 a) – c). The secretariat was requested to submit the amendments proposals to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions. GRE noted that any modification of the transitional provisions, mentioned in para. 11 above, that GRE might agree upon at the next GRE session in October 2018, would be submitted to the November 2018 session of WP.29 as corrigenda to the basic SLR package which otherwise would be issued in August 2018.

18. The expert of SAE proposed to keep Regulations Nos. 98, 112, 113 and 123 “alive” for the purpose of the recently updated Canadian Federal Motor Vehicle Safety Standard (CMVSS) No. 108 (GRE-79-32-Rev.1). GRE referred this document to IWG SLR for consideration.

GRE-79-08 | UN R53: Proposal for amendments to the 02 series of amendments Proposal prepared by the SLR informal group in cooperation with IMMA to delete definitions in UN R53.02 made redundant because identical definitions already exist in UN R48. The aim of this submission is to confirm UN R48 as the repository for common definitions used across all lighting regulations.
GRE-79-09 | UN R74: Proposal for amendments to the 01 series of amendments Proposal prepared by the SLR informal group in cooperation with IMMA in order to delete definitions in UN R74.01 made redundant because they already exist in UN R48. The aim of this proposal is to confirm UN R48 as the sole repository for common definitions used across all lighting regulations.
GRE-79-10 | Proposal to introduce transitional provisions in the text of the draft new UN Regulations on LSD, RID and RRD Proposal from the SLR informal group to introduce transitional provisions in documents GRE/2018/2, GRE/2018/3, and GRE/2018/4.
GRE-79-11 | SLR: Proposal to improve the general requirements for the "Change Index" Proposal from the SLR informal group to improve the general requirements proposed in documents GRE/2018/16 and GRE/2018/18.
GRE-79-12/Rev.1 | SLR: Explanation of the “Change Index” 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.
GRE-79-13 | SLR: Proposal regarding references to the three new UN Regulations on LSD, RID and RRD Proposal from the SLR informal group to improve and correct the official documents to introduce references to the three new simplified UN Regulations on LSD, RID and RRD.
GRE-79-14 | SLR: Proposal to amend the draft UN Regulations on LSD, RRD, and RID Proposal from the SLR informal group to improve and correct the text of the three new simplified UN Regulations on LSD, RID and RRD.
GRE-79-17/Rev.1 | LSD: India comments on the draft new UN Regulation (document GRE/2018/2) Proposal for amendments to the draft text.
GRE-79-18/Rev.1 | RID: India comments on the draft new Regulation Proposal for changes to the draft Road Illumination Devices (RID) regulation.
GRE-79-22 | India’s comments on underlying principles of approval marking for LSD regulation Proposal for a marking requirement for lamps to be approved under the LSD regulation. This proposal is to take care of specific concerns being observed in the marking of the combined lamps for identification, indication of particular series of amendment for each device and to take care of certain difficulties as seen in the proposal submitted by IWG-SLR document no GRE-78-35-Rev.1.
GRE-79-28 | Progress report of the SLR informal group
GRE-79-31 | Proposal to improve GRE/2018/11 and to introduce new requirements into R48-06 with regard to the validity and installation of type approved lighting and light-signalling devices Proposal to a) improve the transitional provisions presented in GRE/2018/11 with regard to the collective amendments to Regulations Nos. 3, 4, 6, 7, 19, 23, 27, 38, 50, 69, 70, 77, 87, 91, 98, 104, 112, 113, 119 and 123 and b) introduce new requirements into the 06 series of amendments to UN R48 with regard to the validity and installation of type approved lighting and light-signalling devices.
GRE-79-32/Rev.1 | Proposal for amendments to Regulations Nos. 98, 112, 113 and 123 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.
GRE/2018/10 | UN R86: Proposal for Supplement 7 to the original series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the original series of Regulation No. 86.
GRE/2018/11 | Collective amendments to Regulations Nos. 3, 4, 6, 7, 19, 23, 27, 38, 50, 69, 70, 77, 87, 91, 98, 104, 112, 113, 119 and 123 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).
GRE/2018/12 | UN R86: Proposal for Supplement [2] to the 01 series of amendments Proposal from the informal working group on the Simplification of Lighting Regulations to delete definitions in UN R86 that are identical, and therefore redundant, to definitions in UN R48. Thus, UN R48 becomes the sole repository for common definitions across lighting installation and device regulations.
GRE/2018/13 | UN R48: Proposal for Supplement [11] to the 06 series of amendments Proposal from the Simplification of Lighting Regulations informal group to consolidate common definitions of terms concerning lighting, light signalling, retro-reflective devices and device installation into Regulation No. 48. (Definitions specific to particular devices would be maintained in the respective device regulations.)
GRE/2018/14 | UN R74: Proposal for Supplement [10] to the 01 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 01 series of Regulation No. 74.
GRE/2018/15 | UN R53: Proposal for Supplement [2] to the 02 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 02 series of Regulation No. 53.

GRE/2018/2 | LSD: Proposal for a new Regulation on uniform provisions concerning the approval of light-signalling devices (lamps) Proposal from the Simplification of Lighting Regulations informal group to combine provisions of UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87 and 91 into a single regulation. This consolidation aims to streamline the administration and implementation of these lighting regulations while setting the foundation for a future shift towards performance-based approval requirements. This proposal restructures the existing body of lighting regulations without changing their content (e.g., technical requirements).
GRE/2018/3 | RID: Proposal for a new UN Regulation concerning road illumination devices (lamps) and systems for power-driven vehicles Proposal from the informal working group on the Simplification of Lighting Regulations (SLR) for a new UN Regulation on Road Illumination Devices (RID) to supersede UN Regulations Nos. 19, 98, 112 (thus 1, 8, and 20), 113 (thus 56, 57, 72, 76, and 82), 119, and 123.
GRE/2018/30 | UN R48: Proposal for Supplement [6] to the 03 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 03 series of Regulation No. 48.

GRE/2018/7 | UN R48: Proposal for Supplement [12] to the 05 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 05 series of Regulation No. 48.
GRE/2018/8 | UN R48: Proposal for Supplement [18] to the 04 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 04 series of Regulation No. 48.
GRE/2018/9 | UN R86: Proposal for Supplement [1] to the 01 series of amendments Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 01 series of Regulation No. 86.
5. Regulations Nos. 37, 99, 128, and Resolution RE5

19. The expert from IEC proposed amendments to Regulations Nos. 37, 99 and 128 that aligned the approval code for light sources with the approval number as prescribed by Revision 3 of the 1958 Agreement (ECE/TRANS/WP.29/GRE/2018/21 and GRE-78-18). GRE adopted the amendments and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2018 sessions.

GRE-78-18 | Distinction between "approval code" and "approval number" under the 1958 Agreement
GRE/2018/21 | Proposal to amend the approval code for light sources Proposal to align the approval code for light sources approved according to Regulations Nos. 37, 99 and 128, with the approval number as prescribed by Revision 3 of the 1958 Agreement, schedule 4.

20. On behalf of the Task Force on LED retrofits and substitutes (TF SR), the expert from Germany presented their status report (GRE-79-16). GRE supported the proposed two-step approach and mechanical interlock as a solution to avoid misuse of light emitting diode (LED) substitutes.

21. GRE recalled the earlier proposals by GTB to introduce LED substitutes and replaceable light sources into the new LSD and RID Regulations (ECE/TRANS/WP.29/GRE/2017/14, ECE/TRANS/WP.29/GRE/2017/15 and GRE-78-04) and noted that ECE/TRANS/WP.29/GRE/2017/15 had been incorporated in ECE/TRANS/WP.29/GRE/2018/3. GRE invited TF SR to update ECE/TRANS/WP.29/GRE/2017/14 and GRE-78-04.

22. The expert from GTB pointed out that the GTB guidelines for introducing and evaluating LED light source categories that were intended for forward lighting applications (GRE-77-04) should be published as a reference document on the GRE website. GRE agreed to this request.

GRE-78-04 | Correction to the proposal for RID LED substitute light source requirements (GRE/2017/14) Request to delete the amendment to paragraph 3.3.4.1.1. in the proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices. The proposed amendment was included in the submission by mistake.
GRE-79-16 | Report of the Substitute/Replacement Light Sources task force
GRE/2017/14 | Proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices Proposal to introduce the following changes into the draft new Regulation on light-signalling devices:<ol><li>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).</li><li>COP testing of the lamp is required with an (etalon) filament light source only, because the LED substitute is the counterpart light source of the filament light source, resulting in equivalent photometrical lamp performance. The quality i.e. the equivalence to the filament light source, is controlled in R128.</li><li>Use of LED substitute light sources is at the discretion of the applicant, who shall declare this use, if any, to the Approval Authorities at the time of application for the first lamp approval or subsequent extension of approval issued for the version using the LED substitute light source.</li><li>The use of LED substitute light source(s) in a certain lamp type shall be indicated on the lamp by marking of the LED substitute light source category, in addition to the marking of the filament light source of which the LED substitute light source is the counterpart.</li><li>This marking on the lamp will be used for checking the allowance for use of lamps with LED substitute light sources in application of the Regulation on lamps installation on vehicle.</li><li>In case a lamp with colour filter(s) is approved for using LED substitute light source(s), this lamp shall be marked “G” to indicate that this lamp shall be equipped with LED substitute light source(s) marked “G” for colour and luminous intensity quality reasons.</li><li>The indication of both the filament light source and of its LED counterpart light source, if any, shall be explicitly provided in the communication form.</li></ol>
GRE/2017/15 | Proposal to introduce requirements for the use of replaceable light emitting diode light sources for forward lighting in the new Regulation on Road Illumination Devices Proposal to introduce requirements for replaceable light-emitting diode (LED) light sources for forward lighting in the new Regulation on Road Illumination Devices (RID). As the Informal Working Group "Simplification of the Lighting and Light-Signalling Regulations" (IWG SLR) continues working on the new RID Regulation, it is not possible to indicate all detailed modifications that will be required to incorporate the replaceable LED light sources for forward lighting. However, in general, only simple editorial changes will be required. Further work is required to identify the changes that will be required in the annexes.
GRE/2018/3 | RID: Proposal for a new UN Regulation concerning road illumination devices (lamps) and systems for power-driven vehicles Proposal from the informal working group on the Simplification of Lighting Regulations (SLR) for a new UN Regulation on Road Illumination Devices (RID) to supersede UN Regulations Nos. 19, 98, 112 (thus 1, 8, and 20), 113 (thus 56, 57, 72, 76, and 82), 119, and 123.
6. (a) Regulation No. 48: Proposals for amendments to the 05 and 06 series of amendments

23. The expert from GTB proposed to harmonize the switching requirements for side-marker and position lamps when mutually incorporated (ECE/TRANS/WP.29/GRE/2017/24). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments to Regulation No. 48. The expert from France corrected the French text of the adopted amendment (Annex IX).

GRE/2017/24 | Proposal for Supplement 11 to the 06 series of amendments to Regulation No. 48 Proposal to enable approval of side-marker and position lamps with regard to switching requirements when mutually incorporated. Vehicles include designs where lamps wrap around vehicle corners. In cases where optional side-marker lamps are grouped with a position lamp that is reciprocally incorporated with the direction indicator, it should be possible to switch off the side-marker lamp (as can be done with the position lamp) in order to improve conspicuity of the direction indicator.

24. The expert from OICA introduced a revised proposal which defined and described the operation of the external status indicator for vehicle alarm systems, alarm systems and immobilizers, as contained in Regulations Nos. 97 and 116 (GRE-77-25-Rev.2). Following an in-depth discussion, GRE adopted this proposal, as contained in Annex X, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments and a draft Supplement 12 to the 05 series of amendments to Regulation No. 48.

GRE-77-25/Rev.2 | UN R48: Proposal for a consolidated version of GRE/2016/33 and GRE-76-17 Proposal to define specifications for the design and operation of external status indicators for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers under UN R48 pursuant to provisions of UN R97 and R116.

25. The expert from GTB proposed correcting errors and discrepancies in the text of the 05 and 06 series of amendments to Regulation No. 48 (GRE-78-05). GRE adopted the proposals, as contained in Annex XI, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 11 to the 06 series of amendments and a draft Supplement 12 to the 05 series of amendments to Regulation No. 48. GRE also requested GTB to verify whether or not these amendments are relevant for the 03 and 04 series of amendments to Regulation No. 48 and to report back to GRE at its next session in October 2018.

GRE-78-05 | Correction of errors and discrepancies in the 05 and 06 series of amendments to Regulation No. 48 Proposal to address inconsistencies, clarify text, and correct terminology in Regulation No. 48:<ul><li>para. 5.7.2.1. editorial alignment of text with current terminology</li><li>replace undefined "effective outlet" terminology with defined "apparent surface" reference</li><li>reintroduction of missing reference to "transverse plane" in paras. 5.10.1. and 5.10.2.</li><li>para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria</li><li>para. 6.26.9.2. to correct a cross-reference with UN R23.</li></ul>

26. The experts from the Task Force on Headlamp Switching (TF HS) and from SAE introduced alternative proposals which corrected and clarified the requirements for Daytime Running Lamps (DRL) (ECE/TRANS/WP.29/GRE/2018/20, ECE/TRANS/WP.29/GRE/2018/22 and GRE-79-26). The expert from Japan commented on the proposals (GRE-79-03-Rev.1). Following a brief exchange of views, GRE invited the Co-Chairs of TF HS to prepare a consolidated proposal for consideration at the next session.

27. The expert from Czechia proposed to correct and clarify the requirements for DRLs in conjunction with rear position lamps (ECE/TRANS/WP.29/GRE/2017/23). GRE invited the Co-Chairs of TF HS to take these proposals into account when preparing a consolidated document.

GRE/2017/23 | Proposal for Supplement 11 to the 06 series of amendments to Regulation No. 48 Proposal to re-insert paragraph 5.11.1.3. with regard to switching between headlamps and DRLs. Although GRE agreed to delete this and related paragraphs during its 77th session (see para. 19 and Annex II of the 77th session report), the Task Force on Headlamp Switching decided upon further review to retain the possibility to switch ON DRLs in conjunction with at least the rear position lamps without the need for the position lamps tell-tale in that case.

28. The experts of Germany and Italy proposed a new series of amendments to Regulation No. 48 to clarify the DRL switching-off conditions and/or light intensity reduction when DRL and front direction indicators were totally or partially reciprocally incorporated and when the distance between them was equal or less than 40 mm (GRE-79-25). The expert from OICA submitted a counter-proposal (GRE-79-30). GRE invited the proponents to prepare a consolidated document for the next session.

GRE-79-25 | Proposal for the 07 series of amendments to UN R48 and for Supplement 20 to UN R87 a) Proposal to amend UN R48 to clarify the DRL switching-off conditions (also aligning them with the existing switching-off conditions for front position lamps reciprocally incorporated with DI) and/or light intensity reduction when DRL and DI are totally or partially reciprocally incorporated and when their distance is equal or less than 40 mm. b) Proposal to introduce into UN R87 the possibility of a supplemental verification and certification of the “reduced luminous intensity”, fulfilling the pertinent requirements in Regulation No. 48.
GRE-79-30 | UN R48 and R87: Comments on proposed amendments (document GRE-79-25) Comments on the proposal from Germany and Italy for the 07 series of amendments to UN R48 and for Supplement 20 to UN R87.
6. (b) Regulation No. 48: Other proposals for amendments

29. The expert from Poland provided a summary of initial aiming and levelling tolerance issue (GRE-79-23, GRE-79-24). The experts from Italy and the Netherlands briefly introduced GRE-79-29 as a discussion paper for the possible introduction of new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height. GRE agreed to keep GRE-79-29 as a reference document for the next session.

GRE-79-23 | UN R48: Summary of initial headlamp aiming and levelling tolerance issue
GRE-79-24 | UN R48: Detailed explanations supporting the summary of initial aiming and levelling tolerance issue (GRE-79-23)
GRE-79-29 | UN R48: Proposal for a new 07 series of amendments Discussion document from the Netherlands and Italy to serve presenting potential new requirements for headlamp levelling, in particular regarding the vertical inclination in relation to the dipped-beam headlamp mounting height. The proposal is based on the original proposal of the Informal Working Group on Visibility, Glare and Levelling (VGL) (informal documents GRE-78-23-Rev.1, GRE-78-32, GRE-78-36) and discussions during the GRE 78th session.

30. GRE noted the slow progress in the work of the Informal Working Group on Visibility, Glare and Levelling (IWG-VGL). To advance the topic, the expert from GTB proposed to bring together various experts on glare and levelling issues for a one-day event, in conjunction with the next session of GRE. GRE supported this idea.

31. GRE took note that WP.29 had extended the mandate of IWG VGL for the year 2018 and recalled its request to IWG VGL to revise its Terms of Reference. The expert from Poland presented his proposals (GRE-79-33). Due to the late availability of GRE-79-33, GRE decided to revert to this issue at the next session. Some experts were of the view that IWG VGL had completed phase I of its mandate and that phase II should be taken over by IWG SLR to avoid duplication in the work of the two IWGs. The Chair invited IWG SLR to address this issue at the next sessions.

GRE-79-33 | Proposal to amend the VGL informal group terms of reference
7. (a) Other Regulations: Regulation No. 10

32. On behalf of the Task Force on Electromagnetic Compatibility (TF EMC), the expert from OICA presented a status report (GRE-79-04) and revised amendment proposals to Regulation No. 10 (ECE/TRANS/WP.29/GRE/2018/5 and GRE-79-05). The expert from India suggested a minor modification (GRE-79-21). The expert from France proposed to extend paragraph 2.12. on immunity-related functions with the aim to cover new car systems recently introduced by other Regulations (GRE-79-27). The expert from EC was of the view that the transitional provisions in ECE/TRANS/WP.29/GRE/2018/5 should be checked for consistency. He further pointed out the need to align the provisions on charging with the new GTR on safety of electric vehicles. The expert from the United States of America called for cooperation between TF EMC and IWG on Electric Vehicle Safety. The expert from OICA invited all interested parties to take part in the next TF EMC meeting in May 2018 (GRE-79-34) and/or provide their written comments to TF EMC before July 2018, to facilitate preparing revised amendment proposals for consideration at the next session of GRE.

The proposal also introduces additional details for vehicle in charging mode operating conditions (alternative or direct current charging).
7. (b) Other Regulations: Regulation No. 50

33. The expert from IMMA presented amendments to Regulation No. 50 regarding inward geometric visibility requirements for rear position lamps, together with corresponding proposal for amendments to regulation No. 53 (ECE/TRANS/WP.29/GRE/2018/27 and ECE/TRANS/WP.29/GRE/2018/28). GRE generally supported these proposals, but recalled its earlier decision to “freeze” Regulation No. 50 which would be replaced by the new LSD regulation. Therefore, GRE invited IMMA to resubmit the proposals once the LSD Regulation would have entered into force.

GRE/2018/27 | UN R50: Proposal for a new Supplement to the 01 series of amendments Proposal to align the angle of visibility requirements for rear position lamps with the angle of visibility requirements for front position lamps. This proposal corresponds with a related proposal on Regulation No. 53 (GRE/2018/28).

34. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan proposed a new requirement for automatic switching from DRL to the headlamp for L3 category (ECE/TRANS/WP.29/GRE/2018/19). The expert from India suggested deletion of the wording “passing beam” from the text (GRE-79-20). Some GRE experts supported in principal ECE/TRANS/WP.29/GRE/2018/19, but expressed concerns about the proposed introduction of a new category of daytime running lamps with the maximum luminous intensity of 700 cd. GRE invited experts to send their comments to the Special Interest Group and agreed to continue consideration of the proposal at the next session.

GRE/2018/19 | UN R53 and LSD: Proposal for the 03 series of amendments and for amendments to the draft new Regulation on light-signalling devices Proposal to require automatic switching from DRL to normal headlamp lighting as conditions warrant, amending the current UN R53 as well as the proposed new UN Regulation on light-signalling devices.

35. The expert from IMMA proposed to clarify that direction indicators may be activated to show the vehicle status when the engine is stopped (ECE/TRANS/WP.29/GRE/2018/25). The experts from Finland, Italy and Netherlands recalled that Regulation No. 48 in similar situations makes clear references to Regulations Nos. 97 and 116. The Chair invited IMMA to consider its proposal in line with the logic of Regulation No. 48.

GRE/2018/25 | UN R53: Proposal for a draft amendment Proposal to clarify the text with regard to the activation of the direction indicators when the motorcycle engine in order to signal the vehicle status. The proposal would specify the purposes for which indicators may be activated:<ol class="alpha"><li>To show the vehicle status (e.g. locking system) when the vehicle is parked;</li><li>To allow the driver to recognize the presence of his/her own vehicle from a certain distance by remote control;</li><li>In case of keyless entry system and of the driver having lost the key fob while riding - to inform the driver that he/she no longer has the key fob and that the vehicle will soon become unable to restart.</li></ol>

36. The expert from IMMA introduced a revised proposal which allowed the use of different stop lamp activation methods and aligned the stop lamp provisions with those applicable for four-wheelers (ECE/TRANS/WP.29/GRE/2018/29). GRE adopted the proposal and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 20 to the 01 series of amendments to Regulation No. 53 and as a draft Supplement 2 to the 02 series of amendments to Regulation No. 53.

GRE/2018/29 | UN R53: Proposal for a new Supplement Proposal to update the definition of “stop lamp” in order to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device.

37. The expert from IMMA presented a proposal on exterior courtesy lamps (ECE/TRANS/WP.29/GRE/2018/26). The experts from Austria and Netherlands asked for clarification under which motorcycle rest positions (main and/or side) the courtesy lamps would be activated. GRE agreed to revert to this issue at the next session.

GRE/2018/26 | UN R53: Proposal for a draft amendment Proposal to allow installation of exterior courtesy lamps on motorcycles by aligning the text with provisions on courtesy lamps in UN R48.

38. The expert from IMMA proposed to align the text of Regulation No. 53 with Regulation No. 48 and to correct a mistake in the past amendment process (ECE/TRANS/WP.29/GRE/2017/26). GRE adopted the proposal and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 20 to the 01 series of amendments to Regulation No. 53 and as a draft Supplement 2 to the 02 series of amendments to Regulation No. 53.

GRE/2017/26 | Proposal for Supplement 20 to the 01 series of amendments to Regulation No. 53 and for Supplement 2 to the 02 series of amendments to Regulation No. 53 Proposal to remove the prohibition against lamps "reciprocally incorporated" with any other lamp. This proposal would align UN R53 with UN R48 and correct an oversight from a previous amendment process.

39. The expert from India presented GRE-78-24, which replaced GRE-77-08, with the aim to make, under certain conditions, the front position lamp optional for L3 category of vehicles. The experts from Austria, Italy, Finland and Netherlands pointed out the need to study this proposal in more detail. The Chair invited the expert from India to submit an official document for consideration at the next session.

GRE-78-24 | UN R53: Proposals for Supplement 1 to the 02 series of amendments and Supplement 19 to the 01 series of amendments Two part proposal to a) make the fitting of front position lamps optional and b) allow for its separate control under certain conditions and for rear positions lamps and registration plate lamps to be lit during the period between the activation of the master switch and the engine start.

40. GRE noted that GRE-77-09, GRE-77-17 and GRE-78-22, which had not been addressed at the previous sessions due to lack of time, had been superseded by other proposals considered at this session.

GRE-77-09 | India Comments on glare given to oncoming vehicles by motorcycle DRLs at night
GRE-77-17 | Discussion of DRL automatic switching proposal for Regulation No. 53 During April 2016, Japan presented a study to GRE-75 on the disturbance due to the use of motorcycle daytime running lamps (DRL) at night (see GRE-75-09). A proposal (GRE/2016/35 supported by GRE-76-03) for automatic switching between DRL and headlamps was then presented during October 2016 at GRE-76. Italy, among others, raised a reservation. This document details Italy's concerns with the proposal by Japan.
GRE-78-22 | Proposals for a collective amendment to Regulation No. 53 and draft Regulation on Light Signalling Devices (LSD) Proposal from the special interest group of experts for DRL-L to introduce requirements for automatic switching from daytime running lamps (“DRL”) to headlamp(s) if maximum luminous intensity of DRL is above 700 cd.

GRE/2018/23 | UN R74: Proposal for the 02 series of amendments Proposal to require the installation of direction indicator lamps on mopeds.

42. The expert from Czechia proposed to clarify the requirements of driving and passing beam headlamps for mopeds (ECE/TRANS/WP.29/GRE/2018/24). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 10 to the 01 series of amendments to Regulation No. 74.

GRE/2018/24 | UN R74: Proposal for a new Supplement to the 01 series of amendments Under UN R112, a Class B lighting device that fulfills the requirements for Class A headlamps may be approved. However, UN R74 prohibits the use of Class B devices in this manner. Therefore, this proposal would remove the discrepancy and enable the installation of Class B devices approved under UN R112 as headlamps.
8. (a) Other business: Amendments to the Convention on Road Traffic (Vienna, 1968)

43. The Secretary of the Global Forum for Road Traffic Safety (WP.1) briefed GRE on the outcome of the March 2018 session of WP.1. In particular, WP.1 had nearly finalized considering the amendment proposals to Article 32 and Chapter II of Annex 5 on lighting and light-signalling (ECE/TRANS/WP.1/2017/1 ). A summary of the WP.1 discussions could be found in the session’s report (ECE/TRANS/WP.1/163, paras. 10-12 ). According to the WP.1 Secretary, the Global Forum would finalize the amendment proposals at its next regular session in September 2018. He also pointed out that, in May 2018, WP.1 would hold an extraordinary meeting to consider a Draft resolution on the deployment of highly and fully automated vehicles in road traffic (ECE/TRANS/WP.1/2018/4/Rev.1 ). The Chair invited GRE experts to review ECE/TRANS/WP.1/2017/1 and to provide their comments, if any, to the secretariat.

WP.1/2017/1/Rev.1 | Revised draft amendment to the Convention on Road Traffic (1968) This document, submitted by the secretariat and originally prepared by Italy, France, and Laser Europe, provides the text of agreed amendments to Article 25bis, Article 32, Annex 1 and Annex 5 of the 1968 Convention on Road Traffic. The amendments notably address "Rules of the use of lamps".
8. (b) Other business: Decade of action for road safety 2011-2020

44. GRE recalled the developments in field of road safety mentioned in the opening statement (para. 5).

8. (c) Other business: Development of the International Whole Vehicle Type Approval

45. GRE noted that UN Regulation No. 0 on the International Whole Vehicle Type Approval (IWVTA) had been adopted at the November 2017 sessions of WP.29 and AC.1 (ECE/TRANS/WP.29/2017/108) and was expected to enter into force in July 2018.

WP.29/2017/108 | Draft UN Regulation No. 0 on uniform provisions concerning the International Whole Vehicle Type Approval Proposal submitted by the informal working group on the International Whole Vehicle Type Approval for the establishment of UN Regulation No. 0 regarding the approval of whole vehicles within the framework of the 1958 Agreement. The regulations would establish an International Whole Vehicle Type Approval (IWVTA) scheme whereby Contracting Parties adhering to the Regulation may issue approvals to either a limited level (L-IWVTA) or to a wider range of technical topics included in the universal level (U-IWVTA). Contracting Parties are able to apply the limited or universal IWVTA depending upon the national situation. The Universal-IWVTA (U-IWVTA) provides a greater level of certainty for vehicle manufacturers and Contracting Parties applying this UN Regulation, as the approval has to be accepted without further assessment of the technical items covered by the U-IWVTA issued. Contracting Parties applying this UN Regulation are not obliged to accept approvals to the limited level (L-IWVTA) but may do so at their choice. However, they have also to accept approvals issued pursuant to U-IWVTA. The UN Regulation includes the administrative obligations of the IWVTA scheme. It does not establish separate technical requirements but instead refers to the provisions of the separate UN Regulations.
8. (d) Other business: Phantom light and colour washout

46. No information was reported on this topic.

9. New business and late submissions

47. The experts of France and Germany initiated a discussion on how to treat lamps with apparent surfaces in the form of a company logo or other brand-identifying figures (GRE-78-03). The experts from Finland, France, Italy Netherlands, Poland, Spain and UK reported on their national experiences on the subject. GRE noted that, in many countries, specific illuminated advertisement on vehicles was prohibited. However, no clear restrictions existed for lamps which otherwise met the requirements of lighting and light-signalling Regulations, and particularly of Regulation No. 48. GRE was also informed about optional additional lamps that were allowed in some countries for the purposes of road safety, for example, additional direction indicators for trucks in the form of a cyclist. The experts from France and Germany pointed out that they would distribute a questionnaire to GRE experts to solicit detailed information on relevant national practices. In addition, the expert from the Netherlands suggested establishing a task force. GRE agreed to revert to this issue at the next session, based on the outcome of the survey.

GRE-78-03 | Evocative, suggestive or figurative apparent surfaces Request for guidance regarding interpretation of UN lighting rules:<ol><li>Is it allowed that the shape of the apparent surface can be the logo of the manufacturer brand or other brand-identifying figures?</li><li>Is it allowed that the shape of the apparent surface can be the same as an evocative/suggestive figure? Even as an informative figure such as road traffic signs?</li><li>Is the advertising lighting allowed at the national level in the Contracting parties, regarding to its influence on road safety and distraction?</li><li>Do we have to consider an apparent surface, whose shape is the logo of a brand manufacturer or other brand-identifying figures, as a advertising lighting?</li></ol>

48. The expert from SAE informed GRE about the recent changes of the national regulation on motor vehicle lighting and light signalling in Canada and of the associated technical standard document (GRE-79-06 and GRE-79-07). GRE took note of this information.
