53. The secretariat, on behalf of the Chair of GRE, reported on the results of the eighty-second session of GRE (for details, see ECE/TRANS/WP.29/GRE/82).

50. The World Forum recalled the report of the Chair of GRE on its eighty-second session (ECE/TRANS/WP.29/GRE/82) and approved the report.

Proposal from the Simplification of Lighting Regulations informal group to delete the luminous intensities minimum requirements for the measuring point 50L (which are not in UN R112 and therefore should not be in UN R149) from Table 8 and to correct a typo in the angular position for S100RR in Table 13. Given the importance of these corrections, this proposal is simultaneously being submitted as a formal document for consideration during the WP.29 session in November 2019.

8. GRE was informed that the three new simplified UN Regulations Nos. [148] on Light-Signalling Devices (LSD), [149] on Road Illumination Devices (RID) and [150] on Retro-Reflective Devices (RRD) were expected to enter into force on 15 November 2019. GRE noted that IWG SLR had identified errors inadvertently introduced in the text of the new UN Regulation No. [149] and that a correction had been submitted to the WP.29 session in November 2019 (ECE/TRANS/WP.29/2019/125, GRE-82-02). GRE supported the correction.

Guide prepared by the GRE Substitutes/Retrofits Task Force to criteria for specifying LED substitute light source categories as equivalents for corresponding fliament light source categories.

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.

The proposal opens the opportunity to project driver assistance symbols on the road ahead the vehicle as part of the Adaptive Driving Beam by introducing angular limits for the placement of these projections as well as luminous intensity limits in order to guarantee a good perceptibility of the symbols for the driver at night time without distracting other road users.

47. The expert from GTB presented driver assistance projections as a new feature of the adaptive driving beam with the aim to increase driver’s comfort and road safety (GRE-82-40). The presentation was accompanied by a live demonstration of three vehicles equipped with the new feature. To allow for the driver assistance projections, the expert proposed amendments to UN Regulations Nos. 48 and [149] (GRE-82-04, GRE-82-40).

48. GRE welcomed both GTB presentation and demonstration. Several experts were of the view that the new system could bring safety benefits provided that:

• Road projections symbols are standardized (e.g. according to UN Regulation No. 121).
• Road projections symbols do not distract other drivers.

Proposal to restore the correct value for the vertical visibility angle requirement.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption. Having extensively discussed this issue, GRE agreed that the rear position lamps “shall” be on in case of adverse weather conditions, however, the list of such conditions would need to be improved. GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.

Proposal to align UN R48 with provisions in UN R4 by introducing parameters for luminance levels, maximum gradient value, angles of visibility and light incidence angle which are necessary to determine the geometric position of devices in relation to the rear registration plate.

27. The expert from Poland proposed modifications to provisions on the rear registration plate lamps (GRE-82-08). Following a brief exchange of views, GRE invited the expert to submit a formal document for consideration at the next session.

Proposal to clarify the definition of “‘on’ time” (t_H) to address cases where a single flash consists of several flashes.

38. The expert from Poland proposed to clarify the definition of the “on” time for the case of a group of flashes (GRE-82-09). The expert from GTB pointed out that the GTB Working Group Photometry had recently considered an alternative wording for the same purpose. GRE invited both experts to submit a new proposal to the next session.

Proposal to include daytime running lamps in the provision for ‘an assembly of two independent lamps to be type approved as lamp marked “D”’.

50. The expert from Poland proposed to add a reference to DRL in paragraph 4.4.1. of UN Regulations No. [148] (GRE-82-10-Rev.1). The expert from IWG SLR stated that this proposal would be included into the consolidated package of amendments to the above UN Regulation.

Proposal of corrections to the original document from the group of interested experts.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

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.

Proposal to enable the approval of Category L₃ equipped with adaptive driving beam (ADB) headlamps under UN R53 and R149.

36. The expert from IMMA recalled the requirements on Adaptive Driving Beam (ADB) in UN Regulation No. 48 and proposed similar provisions for amending UN Regulation No. 53 (GRE-82-13, GRE-82-18, GRE-82-46-Rev.1). Following a brief exchange of views, the Chair invited GRE experts to send their comments to IMMA with a view to preparing an official document for consideration at the next session.

2. GRE considered and adopted the agenda (ECE/TRANS/WP.29/GRE/2019/1), as reproduced in GRE-82-01 together with the informal documents distributed during the session. GRE also noted the running order proposed by the Chair (GRE-82-14).

Proposal to remove restrictions on the installation of lighting devices on L₁ and L₃ category vehicles that are permitted for M, N, and T category vehicles.

51. The expert from India proposed deleting the prohibition to use lighting and light-signalling devices other than those prescribed in UN Regulations Nos. 53 and 74 (GRE-82-15). Several experts disagreed with this proposal and therefore GRE did not support it.

Proposal to clarify the content of GRE/2019/23, aimed at ensuring that the new 03 series of amendments to UN Regulation No. 53 contains the latest proposals adopted by GRE regarding preceding series.

35. The expert from IMMA presented a consolidated text of the draft 03 series of amendments to UN Regulation No. 53 which had incorporated the latest modifications to the 01 and 02 series (ECE/TRANS/WP.29/GRE/2019/23 and GRE-82-16). GRE noted that these modifications had been also included in the draft 03 series of amendments to UN Regulation No. 53 submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80).

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.

Comparison of adaptive driving beam provisions between the current UN Regulation No. 48 and the proposal for amendments to UN Regulation No. 53 (GRE-82-13).

36. The expert from IMMA recalled the requirements on Adaptive Driving Beam (ADB) in UN Regulation No. 48 and proposed similar provisions for amending UN Regulation No. 53 (GRE-82-13, GRE-82-18, GRE-82-46-Rev.1). Following a brief exchange of views, the Chair invited GRE experts to send their comments to IMMA with a view to preparing an official document for consideration at the next session.

4. GRE took note of the highlights of the June 2019 session of WP.29 and the official document submission deadline of 24 January 2020 for the April 2020 session of GRE (GRE-82-19).

Proposal to improve the proposal submitted by the experts from France and Germany to allow under specified conditions the use of manufacturer logos inside the illuminant surface of a signalling lamp.

16. The experts from France and Germany presented an updated proposal for amendments to UN Regulations Nos. 48 and 148, which introduce conditions for the use of logos of the vehicle or body manufacturer inside the illuminating surface of a signalling lamp (ECE/TRANS/WP.29/GRE/2019/28 and GRE-82-32). The expert from CLEPA proposed adding the logo of the lamp manufacturer (GRE-82-20). The expert from OICA suggested a modified definition of “manufacturer logo” (GRE-82-36).

17. Several experts expressed their preference to completely prohibit the use of logos inside the lamps on safety concerns, while some others pointed out that road safety would not be compromised, as the lamps should meet all requirements in the respective UN Regulations. Some experts wondered whether the use of letters inside the logos was allowed. Following an in-depth discussion, GRE agreed that the “manufacturer logo” definition would need further clarification and invited the experts from France and Germany to submit a revised proposal for consideration at the next session. Pending the outcome of this discussion, GRE invited type approval authorities to refrain from granting type approvals to signalling lamps with logos inside the illuminating surface.

Proposal to clarify the conditions under which the vehicles may circulate with the dipped beam headlamps switched OFF.

28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption.

GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.

Proposal to rectify the transitional period for recently amended provisions applicable to the installation of lighting and light-signalling devices for L3 vehicles.

37. The expert from EC recalled the draft 03 series of amendments to UN Regulation No. 53, which were submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80) and proposed to shorten its transitional period from 1 September 2023 to 1 September 2021 (GRE-82-22). The expert from IMMA pointed out the technical challenges of implementing the 03 series of amendments and suggested that the original transitional provisions should be maintained (GRE-82-37). Following an in-depth discussion, GRE decided to keep the transitional period unchanged. At the same time, GRE agreed to scrutinize all future requests for long transitional provisions by the industry.

Proposal to clarify the transitional provisions for the mandatory use of Emergency Stop Signal (ESS).

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

32. On behalf of the Task Force on Electromagnetic Compatibility (TF EMC), the expert for OICA presented their status report (GRE-82-24).

Proposal concerning the conditions under which the vehicles may circulate with the dipped beam headlamps switched OFF from the SLR informal group to based on document ECE/TRANS/WP.29/GRE/2019/03 taking into account the agreed modifications to the diagram introduced with GRE-81-21 (see ECE/TRANS/WP.29/GRE/81, Annex II).

31. The expert from IWG SLR recalled the previous discussions on the aiming diagram in paragraph 6.2.6.1.2. (ECE/TRANS/WP.29/GRE/81, para. 10 and Annex II) and presented GRE-82-25, which had been prepared in line with the GRE request. The expert from Poland proposed a revised diagram (GRE-82-43). For the diagram in GRE-82-25, the experts from Japan, Poland and the United Kingdom expressed their preference to maintain the 2000 lm criteria for automatic levelling and headlamp cleaning. The experts from Germany and the United Kingdom pointed out the need to consider the aiming tolerance for the purposes of, respectively, Periodic Technical Inspections (PTI) and Conformity of Production (CoP). GRE requested IWG SLR to consider the above elements and to prepare a revised document for the next session of GRE.

Consolidated proposal incorporating the proposal to correct a paragraph reference (‘3.3.2.2’ in place of ‘3.2.3.2’) and to insert a provision from UN R3 (para. 4.1.2.) unintentionally omitted from the original text and the proposal to improve the text, add 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.

12. GRE also noted draft consolidated proposals for amendments to UN Regulation Nos. [148] and [150] (GRE-82-30 and GRE-82-26). The Chair invited GRE experts to review these documents and send their comments to IWG SLR.

Proposal to restore the sequential activation of direction indicators of categories 11, 11a, 11b, 11c and 12, which were included in UN Regulation No. 50 but omitted when UN R148 was developed during SLR Stage 1. The corresponding references to UN Regulation Nos. 53 and 86 have been included.

11. At the proposal to IWG SLR, GRE adopted further corrections to UN Regulation No. [148] (GRE-82-27, GRE-82-28, GRE-82-29 and Annex II) and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2020 sessions.

54. In particular, he informed WP.29 about the adopted draft new series of amendments to UN Regulation No. 48 that introduces the mandatory use of Emergency Stop Signal (ESS). He further mentioned that GRE agreed to correct few mistakes and omissions in the new simplified UN Regulations Nos. [148], [149] and [150]. He recalled that, according to the WP.29 mandate, the requirements in the original series of the three new UN Regulations should be totally identical to the requirements in the device UN Regulations which had been frozen in the course of the simplification process. Therefore, GRE was of the view that eventual discrepancies should be corrected by means of supplements or corrigenda to the original series of the new UN Regulations, while substantial changes should only be introduced by the 01 series of amendments and its supplements.

Proposal to differentiate light source modules in cases where a signalling device contains more than one different module. The proposal adds the missing provision for multiple light source modules that is present in paragraph 3.6.2. of UN R7 and should be transposed into this regulation.

11. At the proposal to IWG SLR, GRE adopted further corrections to UN Regulation No. [148] (GRE-82-27, GRE-82-28, GRE-82-29 and Annex II) and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2020 sessions.

The document was prepared by the GRE-IWG SLR to show the latest status of work and collect feedback from GRE for the preparation of the final proposal that will be submitted to the 83rd GRE session.

12. GRE also noted draft consolidated proposals for amendments to UN Regulation Nos. [148] and [150] (GRE-82-30 and GRE-82-26). The Chair invited GRE experts to review these documents and send their comments to IWG SLR.

19. The expert from IWG SLR reported on the challenges of implementing the Unique Identifier (UI) in the new simplified UN Regulations (GRE-82-31) in the light of the progress of IWG on Database for the Exchange of Type Approval Documentation (DETA). GRE reiterated its view that for lighting and light-signalling devices, approval markings should be replaced by UI. At the same time, GRE noted that the access rights currently proposed by IWG DETA would not be sufficient for the efficient use of UI for the lighting and light-signalling UN Regulations. GRE mandated IWG SLR and the Chair to bring the specific GRE needs for the DETA access rights to the attention of IWG DETA and WP.29 at their forthcoming sessions in November 2019.

16. The experts from France and Germany presented an updated proposal for amendments to UN Regulations Nos. 48 and 148, which introduce conditions for the use of logos of the vehicle or body manufacturer inside the illuminating surface of a signalling lamp (ECE/TRANS/WP.29/GRE/2019/28 and GRE-82-32).

Proposal to correct the reference to paragraph 5.3.1.5.3. (found in paragraph 5.3.2.8.2. of the current text) with 5.3.1.4.3.

13. The expert from Italy proposed to correct a wrong reference in UN Regulation No. [149] (GRE-82-33). GRE adopted the correction (Annex III) and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions.

Proposal to amend the transitional provisions.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

Proposal for changes to the draft provisions to define switching conditions for dipped beam and daytime running lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions.

28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption. Having extensively discussed this issue, GRE agreed that the rear position lamps “shall” be on in case of adverse weather conditions, however, the list of such conditions would need to be improved. GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.

16. The experts from France and Germany presented an updated proposal for amendments to UN Regulations Nos. 48 and 148, which introduce conditions for the use of logos of the vehicle or body manufacturer inside the illuminating surface of a signalling lamp (ECE/TRANS/WP.29/GRE/2019/28 and GRE-82-32). The expert from CLEPA proposed adding the logo of the lamp manufacturer (GRE-82-20). The expert from OICA suggested a modified definition of “manufacturer logo” (GRE-82-36).

Some experts wondered whether the use of letters inside the logos was allowed. Following an in-depth discussion, GRE agreed that the “manufacturer logo” definition would need further clarification and invited the experts from France and Germany to submit a revised proposal for consideration at the next session. Pending the outcome of this discussion, GRE invited type approval authorities to refrain from granting type approvals to signalling lamps with logos inside the illuminating surface.

Comments particularly with regard to the transitional provisions for the 03 series of amendments.

37. The expert from EC recalled the draft 03 series of amendments to UN Regulation No. 53, which were submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80) and proposed to shorten its transitional period from 1 September 2023 to 1 September 2021 (GRE-82-22). The expert from IMMA pointed out the technical challenges of implementing the 03 series of amendments and suggested that the original transitional provisions should be maintained (GRE-82-37). Following an in-depth discussion, GRE decided to keep the transitional period unchanged. At the same time, GRE agreed to scrutinize all future requests for long transitional provisions by the industry.

Japan basically agrees with the proposal made by Germany but considers that certain points need clarification.

18. The expert from Germany presented an updated proposal which introduces requirements for testing the sun load impact into UN Regulation No. [148] (ECE/TRANS/WP.29/GRE/2019/22). He further indicated that these amendments should be introduced by a new 01 series of amendments to UN Regulation No. [148], together with transitional provisions. The proposal received comments from Japan (GRE-82-38). The experts from the United Kingdom, CLEPA and OICA requested justification for additional testing in ECE/TRANS/WP.29/GRE/2019/22. Finally, GRE invited the expert from Germany, in cooperation with Japan, CLEPA and OICA, to complement the document with transitional provisions and research justification.

7. The expert from the Informal Working Group Simplification of the Lighting and Light-Signalling Regulations" (IWG SLR) reported on their progress (GRE-82-39). He requested GRE to provide guidance on the future development of UN Regulation No. [149] concerning the light sources and reduction in the number of beams. GRE agreed with the approach envisaged by IWG SLR.

47. The expert from GTB presented driver assistance projections as a new feature of the adaptive driving beam with the aim to increase driver’s comfort and road safety (GRE-82-40). The presentation was accompanied by a live demonstration of three vehicles equipped with the new feature. To allow for the driver assistance projections, the expert proposed amendments to UN Regulations Nos. 48 and [149] (GRE-82-04, GRE-82-40).

48. GRE welcomed both GTB presentation and demonstration. Several experts were of the view that the new system could bring safety benefits provided that:

• Road projections symbols are standardized (e.g. according to UN Regulation No. 121).
• Road projections symbols do not distract other drivers.

This proposal base on document GRE/2019/20 and is an alternative to document GRE/2019/14.
Currently, UN Regulation No. 48 does not allow the manual switching off all lighting devices under all circumstances. This feature is necessary for armed services and forces responsible for maintaining public order and is requested by them. It is limited only to vehicles intended for use by the armed services and forces responsible for maintaining public order. This proposal aims to reduce disadvantages and can increase safety.

26. The expert from Germany tabled a proposal that allows the manual switch-off of all lighting devices in vehicles used by authorities responsible for maintaining public order (ECE/TRANS/WP.29/GRE/2019/14 and GRE-82-41-Rev.1). Some experts were of the view that such a derogation should be addressed in the framework of national or regional rather than international law. Several experts indicated practical difficulties in identifying those vehicles when at the stage of type approval and manufacturing. GRE agreed to revert to the issue at the next session.

Draft ITC Recommendations for enhancing National Road Safety Systems following the decisions taken at 81st ITC Plenary Session February 2019

44. The secretariat reported that ITC, at its eighty-first session in 2019, had adopted the ITC Strategy until 2030, invited its subsidiary bodies to follow-up by aligning their work with the strategy and requested the secretariat to take the necessary actions to promote the implementation of the strategy (ECE/TRANS/288, paras. 15 (a), (c) and (g)). Furthermore, the Committee had expressed its concern for the limited progress in meeting the Sustainable Development Goal targets on road safety and those of the United Nations Decade of Action for Road Safety (ibid, para. 64) (GRE-82-42).

45. GRE noted that, in order to help countries, particularly new contracting parties, to further implement legal instruments in the area of road safety, the secretariat had prepared the draft ITC Recommendations for Enhancing National Road Safety Systems for comments by the Working Parties. GRE stressed the importance of this document and invited GRE experts to transmit their comments to the secretariat by 5 November 2019 at the latest.

The IWG-VGL group proposed that the CoP requirements would be the same as for the type-approval. Therefore, Poland will not support the proposal to extend them by another 0.4%.

31. The expert from IWG SLR recalled the previous discussions on the aiming diagram in paragraph 6.2.6.1.2. (ECE/TRANS/WP.29/GRE/81, para. 10 and Annex II) and presented GRE-82-25, which had been prepared in line with the GRE request. The expert from Poland proposed a revised diagram (GRE-82-43). For the diagram in GRE-82-25, the experts from Japan, Poland and the United Kingdom expressed their preference to maintain the 2000 lm criteria for automatic levelling and headlamp cleaning. The experts from Germany and the United Kingdom pointed out the need to consider the aiming tolerance for the purposes of, respectively, Periodic Technical Inspections (PTI) and Conformity of Production (CoP). GRE requested IWG SLR to consider the above elements and to prepare a revised document for the next session of GRE.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

In the leaning condition, the operation of the ADB lamp and its effect do not change from the non-leaning condition which turns off the segment where a camera has detected preceding and/or oncoming vehicle(s).Therefore, there is no additional requirement for the leaning condition.

36. The expert from IMMA recalled the requirements on Adaptive Driving Beam (ADB) in UN Regulation No. 48 and proposed similar provisions for amending UN Regulation No. 53 (GRE-82-13, GRE-82-18, GRE-82-46-Rev.1). Following a brief exchange of views, the Chair invited GRE experts to send their comments to IMMA with a view to preparing an official document for consideration at the next session.

Proposal to allow the manual switching off all lighting devices in all circumstances for vehicles intended for use by the armed services and forces responsible for maintaining public order.

26. The expert from Germany tabled a proposal that allows the manual switch-off of all lighting devices in vehicles used by authorities responsible for maintaining public order (ECE/TRANS/WP.29/GRE/2019/14 and GRE-82-41-Rev.1). Some experts were of the view that such a derogation should be addressed in the framework of national or regional rather than international law. Several experts indicated practical difficulties in identifying those vehicles when at the stage of type approval and manufacturing. GRE agreed to revert to the issue at the next session.

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.

Proposal for corrections to UN Regulation 65 (Special Warning Lamps) based upon Supplement 10 to the original Regulation. A recent review of the content of UN Regulation 65 has revealed some long-standing editorial errors that do not affect the technical requirements but do create confusion.

39. The expert from GTB proposed corrections (ECE/TRANS/WP.29/GRE/2019/17). GRE supported the amendments but decided to postpone their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.

38. The expert from GTB submitted an amendment proposal with the aim to clarify the definition of the “on” time for a group of flashes as well as to correct editorial errors (ECE/TRANS/WP.29/GRE/2020/18). GRE adopted this 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 11 to the original series of amendments to UN Regulation No. 65.

39. GRE also recalled that, at its previous session, it had adopted the corrections proposed by GTB (ECE/TRANS/WP.29/GRE/2019/17) but had postponed their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.

Proposal to render optional the fitment of front position lamps where the motorcycle is fitted with automatic headlamp switching or daytime running lamps meeting certain conditions and to add provisions regarding electrical connections and the activation of simultaneous lamps (e.g., to permit activation of rear lamps before the front lamps are activated).

34. The expert from India proposed making optional the fitment of front position lamps (ECE/TRANS/WP.29/GRE/2019/18). The experts from France, Germany and the Netherlands were not in a position to support the proposal. The expert from India invited GRE to consider only the modification to paragraph 5.10. in ECE/TRANS/WP.29/GRE/2019/18. Following a brief exchange of views, GRE invited the expert from India to submit a separate document on the issue.

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 by a GRE Special Interest Group to define switching conditions for dipped beam and daytime running lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions.

28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption. Having extensively discussed this issue, GRE agreed that the rear position lamps “shall” be on in case of adverse weather conditions, however, the list of such conditions would need to be improved. GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.

Proposal from the GRE Task Force on Substitutes/Retrofits to introduce a new light emitting diode (LED) substitute light source category H11/LED for road illumination applications.

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.

Proposal to introduce requirements for testing the sun load impact, which can delay the perception of a signal in such a way that it may became a serious safety issue, if the sun load impact goes above a defined ratio.

18. The expert from Germany presented an updated proposal which introduces requirements for testing the sun load impact into UN Regulation No. [148] (ECE/TRANS/WP.29/GRE/2019/22). He further indicated that these amendments should be introduced by a new 01 series of amendments to UN Regulation No. [148], together with transitional provisions. The proposal received comments from Japan (GRE-82-38). The experts from the United Kingdom, CLEPA and OICA requested justification for additional testing in ECE/TRANS/WP.29/GRE/2019/22. Finally, GRE invited the expert from Germany, in cooperation with Japan, CLEPA and OICA, to complement the document with transitional provisions and research justification.

Proposal to align the 03 series of amendments to UN R53 (as adopted during GRE-81: GRE/2018/50, as amended by GRE/2019/12) with the latest proposals for amendments to the 01 and 02 series (as adopted by GRE but not yet in force at the time of the present proposal:

1. Add references to UN R148, R149, and R150 (WP.29/2018/104/Rev.1 as amended by WP.29-177-07, and WP.29/2018/105), implementing the change index and amending the definitions (taking into consideration informal document GRE-80-05),
2. Align UN R53 with UN R148 regarding the inward geometric visibility requirements for rear position lamps (GRE/2018/28),
3. Clarify the use of direction indicators to show the status of the device for protection of a vehicle against unauthorised use and allow exterior courtesy lamps to be fitted on motorcycles (WP.29/2019/17 as amended by para. 107 of the session report and WP.29/2019/18 as amended by para. 108),
4. Align UN R53 with UN R48 and correct a mistake in a previous amendment process (WP.29/2018/86/Rev.1 andWP.29/2018/87/Rev.1),
5. Allow the use of different stop lamp activation methods, aligning the definition of “stop lamp” with UN R48 (GRE/2018/29), and
6. Introduce requirements for light emitting diode (LED) substitute light sources (GRE/2018/41).

35. The expert from IMMA presented a consolidated text of the draft 03 series of amendments to UN Regulation No. 53 which had incorporated the latest modifications to the 01 and 02 series (ECE/TRANS/WP.29/GRE/2019/23 and GRE-82-16). GRE noted that these modifications had been also included in the draft 03 series of amendments to UN Regulation No. 53 submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80).

9. The expert from IWG SLR introduced corrections of mistakes and omissions in the text of the new UN Regulations Nos. [148], [149] and [150] (ECE/TRANS/WP.29/GRE/2019/24, ECE/TRANS/WP.29/GRE/2019/25 and ECE/TRANS/WP.29/GRE/2019/26). GRE adopted the corrections and mandated the secretariat to submit them to WP.29 and the Administrative Committee (AC.1) for consideration at their March 2020 sessions. GRE also requested the secretariat to verify with the United Nations Office for Legal Affairs (OLA) whether the adopted corrections could be introduced in the form of corrigenda to the original versions of the three new UN Regulations.

54. In particular, he informed WP.29 about the adopted draft new series of amendments to UN Regulation No. 48 that introduces the mandatory use of Emergency Stop Signal (ESS). He further mentioned that GRE agreed to correct few mistakes and omissions in the new simplified UN Regulations Nos. [148], [149] and [150]. He recalled that, according to the WP.29 mandate, the requirements in the original series of the three new UN Regulations should be totally identical to the requirements in the device UN Regulations which had been frozen in the course of the simplification process. Therefore, GRE was of the view that eventual discrepancies should be corrected by means of supplements or corrigenda to the original series of the new UN Regulations, while substantial changes should only be introduced by the 01 series of amendments and its supplements.

Proposal to require that the vehicle manufacturer’s statement regarding frequency bands, power levels, antenna positions and installation provisions for the installation of radio frequency transmitters (RF-transmitters) be added to the information document (e.g. under item 63, Annex 2A) to facilitate conformity of production and other compliance checks.

33. The expert from the Netherlands proposed improving the text of paragraph of 3.1.8. (ECE/TRANS/WP.29/GRE/2019/27). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft Supplement 1 to the 06 series of amendments to UN Regulation No. 10.

Proposal to allow the use of logos inside the illuminating surface of a signalling lamp under certain conditions.

16. The experts from France and Germany presented an updated proposal for amendments to UN Regulations Nos. 48 and 148, which introduce conditions for the use of logos of the vehicle or body manufacturer inside the illuminating surface of a signalling lamp (ECE/TRANS/WP.29/GRE/2019/28 and GRE-82-32). The expert from CLEPA proposed adding the logo of the lamp manufacturer (GRE-82-20). The expert from OICA suggested a modified definition of “manufacturer logo” (GRE-82-36).

17. Several experts expressed their preference to completely prohibit the use of logos inside the lamps on safety concerns, while some others pointed out that road safety would not be compromised, as the lamps should meet all requirements in the respective UN Regulations. Some experts wondered whether the use of letters inside the logos was allowed. Following an in-depth discussion, GRE agreed that the “manufacturer logo” definition would need further clarification and invited the experts from France and Germany to submit a revised proposal for consideration at the next session. Pending the outcome of this discussion, GRE invited type approval authorities to refrain from granting type approvals to signalling lamps with logos inside the illuminating surface.

Proposal from a GRE Special Interest Group on the 07 series of amendments to UN R48 to clarify the definitions of “switching” and “activation” and to introduce the mandatory use of Emergency Stop Signal (ESS) to align UN R48 with the General Safety Regulation of the European Union.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.
