5. The Chair recalled that GRE was awaiting further progress of automated/autonomous vehicles to see if their light-signalling functions could become a subject for a new UN Global Technical Regulation (UN GTR).

6. No issues were discussed under this agenda item.

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.

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.

GRE-82-02 | Proposal to correct the text of UN R149 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.

WP.29/2019/125 | UN R149: Proposal for Supplement 2 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 its urgency, the proposal has been submitted in parallel for GRE consideration (GRE-82-02).

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.

GRE/2019/24 | Proposal to correct UN Regulation No. [149] (Road Illumination Devices) Proposal to reintroduce the run-up provisions for high-intensity discharge (HID) headlamps that were unintentionally omitted from the original text of UN R149.

GRE/2019/25 | Proposal to correct UN Regulation No. [148] (Light Signalling Devices) Proposal from the Simplification of Lighting Regulations informal group to delete a footnote indicator and delete characters from a figure on the standard light distribution of devices.

GRE/2019/26 | Proposal to correct UN Regulation No. [150] (Retro-Reflective Devices) Proposal from the Simplification of Lighting Regulations informal group 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.

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.

GRE-82-27 | UN R148: Proposal for a Supplement 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.

GRE-82-28 | UN R148: Proposal for a Supplement 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.

GRE-82-29 | UN R148: Proposal for a Supplement Proposal to correct an error in the figure in Annex II, A3-X based on the original figure taken from UN R4, Annex 3 (b).

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.

GRE-82-26 | UN R150: Draft consolidated proposal for amendments 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.

GRE-82-30 | UN R148: Draft consolidated proposal for amendments 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.

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.

GRE-82-33 | UN R149: Proposal for amendments 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.

14. GRE recalled that, according to the mandate of IWG SLR, 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 supplements therein.

15. The expert of IWG SLR recalled that, in the course of the SLR process, the device UN Regulation had been “frozen” by introducing new series of amendments which did not require changes in the approval number (TRANS/WP.29/815, para. 82). He requested the secretariat to include a corresponding footnote in the final consolidated versions of the device UN Regulations.

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.

GRE-82-20 | Proposal for amendments to documents GRE/2019/28 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.

GRE/2019/28 | Proposal for Supplements to UN R148 and R48.06 Proposal to allow the use of logos inside the illuminating surface of a signalling lamp under certain conditions.

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.

GRE-82-38 | UN R48 and R148: Comments on document GRE/2019/22 Japan basically agrees with the proposal made by Germany but considers that certain points need clarification.

GRE/2019/22 | Proposal for Supplements to the new UN Regulation No. [148] and to the 06 and [07] series of amendments to UN Regulation No. 48 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.

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.

GRE-82-31 | Challenges to the implementation of the Unique Identifier

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.

GRE/2019/15 | UN R128: Proposal for Supplement [10] 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.

GRE/2019/16 | RE5: Proposal for amendment [1] to version [2] Proposal to amend light source categories L1A/6 and L1B/6 in the Consolidated Resolution on the common specification of light source categories (R.E.5).

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.

22. GRE agreed to the above activities.

GRE-82-17/Rev.2 | Status report of the Task Force on Substitutes/Retrofits

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] .

GRE/2019/19 | UN R149: Proposal for Supplement [1] Proposal from the GRE Task Force on Substitutes/Retrofits to introduce requirements for LED substitute light sources.

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

WP.29/2019/81 | UN R148: Supplement 1 Proposal to<ul><li>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.”</li><li>amend the inboard visibility angle for rear position lamps in pairs in the new UN Regulation on Light-Signalling Devices (LSD)</li><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>Testing with LED substitute light sources is exempted from conformity of production control.</li><li>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.</li><li>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.</li><li>The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.</li><li>Introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.</li></ul>

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.

GRE/2019/21 | RE5: Proposal for amendment 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.

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.

GRE-82-41/Rev1 | Proposal to amend ECE/TRANS/WP.29/GRE/2019/20 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.

GRE/2019/14 | UN R48: Proposal for a Supplement 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.

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.

GRE-82-08 | Proposal to amend UN R48 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.

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.

GRE/2019/20 | UN R48: Proposal for a new 08 series of amendments 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.

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.

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.

GRE-82-25 | UN R48: Proposal for a new series of amendments 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).

GRE-82-43 | Proposal to amend document GRE-82-25 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%.

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

GRE-82-24 | Status report of the Task Force on Electro-Magnetic Compatibility

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.

GRE/2019/27 | UN R10: Proposal for amendments 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.

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.

GRE/2019/18 | UN R53: Proposal for a new Supplement to the 01 and 02 series of amendments 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).

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).

GRE-82-16 | UN R53: Clarification on document GRE/2019/23 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.

GRE/2019/23 | UN R53: Proposal for a new Supplement to the 03 series of amendments 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:<ol><li>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),</li><li>Align UN R53 with UN R148 regarding the inward geometric visibility requirements for rear position lamps (GRE/2018/28),</li><li>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),</li><li>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),</li><li>Allow the use of different stop lamp activation methods, aligning the definition of “stop lamp” with UN R48 (GRE/2018/29), and</li><li>Introduce requirements for light emitting diode (LED) substitute light sources (GRE/2018/41).</li></ol>

WP.29/2019/80 | UN R53: Proposal for a new 03 series of amendments Proposal to introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd and to restore the original automatic headlamp ON (AHO) requirement for vehicles not equipped with daytime running lamps (DRL) modified by the 03 series.

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.

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.

GRE-82-22 | UN R53: Proposal to amend the 03 series of amendments Proposal to rectify the transitional period for recently amended provisions applicable to the installation of lighting and light-signalling devices for L3 vehicles.

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.

GRE-82-09 | Proposal to amend UN R65 Proposal to clarify the definition of "'on' time" (t_H) to address cases where a single flash consists of several flashes.

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.

GRE/2019/17 | UN R65: Proposal for Supplement [11] 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.

40. GRE was briefed on the activities of IWG on the International Whole Vehicle Type Approval (IWVTA).

41. The Secretary of the Global Forum for Road Traffic Safety (WP.1) reported on the outcome of its session in September 2019. WP.1 had extensively discussed the amendments and decided to resume at the next session with the points (i), (j), (r), (t), 34, 35 and 36 in ECE/TRANS/WP.1/2017/1/Rev.1, and take into account Informal document No. 8 (March 2019), ECE/TRANS/WP.1/2019/10 (submitted by Slovakia) and ECE/TRANS/WP.1/2019/11 (submitted by Laser Europe).

42. He suggested that GRE should appoint a resource person who could participate in WP.1 sessions and would reply to technical questions from WP.1 participants. He also briefed GRE on the WP.1 activity on highly and fully automated vehicles. The Chair recalled the GRE and WP.29 discussions on the signalling requirements for automated/autonomous vehicles (see para. 53 below) and sought the opinion of WP.1 on this matter. To this end, the WP.1 Secretary invited an expert from a contracting party to the Convention on Road Traffic (Vienna, 1968) to submit to the next session of WP.1 in March 2020, a short informal document on the pros and cons of different positions. The expert from Germany volunteered to prepare the paper.

WP.1-78-08 | 1968 Agreement: Proposal to amend document WP.1/2017/1/Rev.1

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".

43. No new information was reported under this agenda item.

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.

GRE-82-42 | Inland Transport Committee (ITC) Strategy 2030 -Special focus: Draft ITC Recommendations for enhancing National Road Safety Systems Draft ITC Recommendations for enhancing National Road Safety Systems following the decisions taken at 81st ITC Plenary Session February 2019

46. Due to lack of time, GRE decided to postpone this issue to the next session.

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.

GRE-82-04 | Proposal to amend UN Regulations Nos. 48 and [149] to allow projections of driver assistance symbols 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.

GRE-82-40 | Driver assistance projections

49. The expert from Japan informed GRE about his intention to commission a study on the reaction time when symbols are used. The expert of Finland recalled an ongoing discussion on the field view assistant within the Working Party on General Safety Provisions (GRSG) and called for cooperation between GRE and GRSG. GRE invited GTB to consider the comments made and decided to revert to the issue at the next session.

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.

GRE-82-10/Rev.1 | Proposal to amend UN R148 Proposal to include daytime running lamps in the provision for 'an assembly of two independent lamps to be type approved as lamp marked "D"'.

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.

GRE-82-15 | Consolidated proposals for amendments to UN Regulations Nos. 53 and 74 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.

52. The secretariat drew the attention of GRE to the fact that the new definition of “External status indicator”, which had been introduced by Supplement 11 to the 06 series of amendments to UN Regulation No. 48 (paragraphs 2.7. and 2.37 of ECE/TRANS/WP.29/2018/84), was left out of Supplement 12 (ECE/TRANS/WP.29/2018/99/Rev.2). GRE requested the secretariat to submit a rectifying document to the March 2020 sessions of WP.29 and AC.1.

WP.29/2018/84 | UN R48: Proposal for Supplement 11 to the 06 series of amendments 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. The proposal also defines 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. The proposal also corrects and clarifies the following:<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><li>measurement of the minimum height in relation to the ground for dipped beam headlamps (para. 5.8.2).</li></ul>

WP.29/2018/99/Rev.2 | UN R48: Proposal for Supplement 12 to the 06 series of amendments Proposal (submitted for the March 2019 WP.29 session) to introduce references to the three new simplified lighting Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into the 06 series of Regulation No. 48.

53. The secretariat reported on the WP.29 considerations, at its June 2019 session, of the signalling requirements for automated/autonomous vehicles (ECE/TRANS/WP.29/1147, paras. 47–50). GRE noted that WP.29 had not been in a position to reach a common position and had referred this issue to WP.1. GRE noted that the Committee for Coordination of Work (WP.29/AC.2) had invited the WP.29 Working Parties (GRs) to identify their priorities with a view to including them into the Programme of Work of WP.29 (ECE/TRANS/WP.29/2019/1/Rev.1). GRE requested IWG SLR to prepare a draft list of GRE priorities.

WP.29/2019/1/Rev.1 | Revised programme of Work of the World Forum for Harmonization of Vehicle Regulations (WP.29) and its Subsidiary Bodies

55. GRE agreed to keep the same structure of the provisional agenda with the new UN Regulations Nos. [148], [149] and [150] becoming sub-items of item 4.

56. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and ECE/TRANS/WP.29/690/Amend.1), GRE called for the election of officers. The representatives of the contracting parties, present and voting, elected unanimously Mr. M. Loccufier (Belgium) as Chair and Mr. D. Rovers (Netherlands) as Vice-Chair for the sessions of GRE scheduled in the year 2020.
