5. The expert of GTB pointed out the growing interest in harmonization of lighting and light-signalling norms among countries which are not Contracting Parties to the 1958 Agreement, in particular, China, India and the United States of America. According to him, Stage 2 of the ongoing process for simplification of the lighting and light-signalling Regulations could also trigger development of a new Global Technical Regulation (GTR), for example, on the adaptive driving beam. The experts from EC and SAE supported this view and called for cooperation with the US National Highway Traffic Safety Administration.

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

7. On behalf of the Informal Working Group ‘Simplification of the Lighting and Light-Signalling Regulations’ (IWG SLR), the expert from GTB reported on the progress and schedule of IWG SLR (GRE-77-32). GRE noted that the three new draft Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD) would be officially submitted to the next session of GRE. The expert of EC urged GRE experts to study these comprehensive documents and to provide their comments and contributions to IWG SLR without delay, so as to have a smooth adoption of the draft Regulations at the next session.

8. GRE took note of a first draft LSD Regulation prepared by IWG SLR (GRE-77-05). GRE commended IWG SLR on the quality of this document and delivered some preliminary remarks on its content. In particular, GRE requested additional explanations on how the amendment process, including new series of amendments and approval markings, would work for the new LSD Regulation which covers many different devices.

9. GTB invited GRE to provide guidance on how to treat the GTB proposals submitted to the previous session of GRE and deferred to the present session for final decision, in the context of drafting the three new Regulations (GRE-77-07). These proposals included the introduction of light emitting diode (LED) substitute light sources in the LSD Regulation (see para. 13 below), introduction of LED light sources in the RID Regulation (para. 15 below) and simplification of the conformity of production (CoP) requirements for adaptive front-lighting systems (AFS) (para. 28 below). GRE agreed to introduce the proposals, if adopted, into the drafts of the new RID and LSD Regulations so that the whole package would be formally submitted to the next session of GRE.

10. The expert from GTB briefly presented his views on Stage 2 of the SLR process and pointed out that it would provide a unique opportunity for China to harmonize their ongoing national simplification process with the SLR requirements.

11. GRE took note that WP.29, at its November 2016 session, adopted the Consolidated Resolution on the common specification of light source categories (ECE/TRANS/WP.29/2016/111) and assigned it number R.E.5. This Resolution would enter into force in June 2017, simultaneously with the corresponding amendments to Regulations Nos. 37, 99 and 128.

WP.29/2016/111 | Proposal for a draft Resolution on the common specification of light source categories (R.E.5) Proposal for a new Consolidated Resolution to simplify the content and amendment process of the light source Regulations Nos. 37, 99 and 128. The data sheets for light sources are moved from Annex 1 of these Regulations to the draft Resolution.

12. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) which introduce requirements and test specifications for light emitting diode (LED) substitute light sources as well as several new LED substitute light source categories (ECE/TRANS/WP.29/GRE/2017/2, ECE/TRANS/WP.29/GRE/2017/3, GRE-77-02, GRE-77-03, GRE-77-15, GRE-77-22). These proposals were accompanied by collective amendments to Regulations Nos. 48, 53, 74, 86 with the requirements for LED substitute light sources (ECE/TRANS/WP.29/GRE/2017/4). The expert from GTB explained that the proposed approach was based on the following principles:

• Lamps may be approved with a filament light source and its corresponding LED substitute light source, when fitting in the same holder, and providing an equivalent photometric performance;
• Lamps equipped with LED substitute light sources should be tested with both the filament lamp and the LED substitute light source.

GRE-77-02 | Equivalence criteria for LED substitute light source categories as equivalents for corresponding filament light source categories

GRE-77-03 | Substitute light sources: equivalence reports for C5W, PY21W, and R5W

GRE-77-15 | Proposal to introduce requirements for the use of LED substitute light sources in the new Regulation for “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.<br/><br/>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-77-22 | Introduction into Regulation 128 of LED Substitute Light Sources

GRE/2017/2 | Proposal for Supplement 7 to the original version of Regulation No. 128 Proposal to<ol class="alpha"><li>introduce provisions for LED substitute light sources into Regulation No. 128;</li><li>introduce new category sheets C5W/LED, PY21W/LED and R5W/LED based on LED technology into the Consolidated Resolution (R.E.5);</li><li> establish equivalence criteria as guidance for specifying sheets for LED substitute light source categories.

GRE/2017/3 | Proposal for amendments to the original version of the Consolidated Resolution on the common specification of light source categories Proposal to introduce new light emitting diode (LED) substitute light source categories C5W/LED, PY21W/LED and R5W/LED. The proposal is part of a package which also includes amendments to Regulation No. 128.

GRE/2017/4 | Proposal for a collective amendment to Regulations Nos. 48, 53, 74, and 86 Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

13. GRE also noted the proposal by GTB to introduce requirements for the use of LED substitute light sources in the new LSD Regulation (GRE-77-15).

GRE-77-15 | Proposal to introduce requirements for the use of LED substitute light sources in the new Regulation for “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.

14. The expert of Germany commented on the GTB proposals (GRE-77-29). GRE generally advocated the idea of allowing for LED substitute lights sources, given their high energy efficiency. At the same time, the experts from France, Germany, Netherlands, Spain and UK pointed out the risks associated with the improper use of aftermarket LED products in lamps, which were not approved for such light sources, and called for developing a set of preventive measures, including raising public awareness and giving warnings to consumers. Several technical issues were also questioned, in particular, the proposed G-marking for LEDs with a correlated colour temperature below 3,000 K. GRE invited GTB to address the comments received and agreed to continue the consideration of this issue at the next session on the basis of revised documents to be prepared by GTB.

GRE-77-29 | Comments from Germany on GRE/2017/2 (Proposal for Supplement 7 to the original version of Regulation No. 128) General observations from Germany concerning all documents related to “LED substitute light sources”.

GRE/2017/2 | Proposal for Supplement 7 to the original version of Regulation No. 128 Proposal to<ol class="alpha"><li>introduce provisions for LED substitute light sources into Regulation No. 128;</li><li>introduce new category sheets C5W/LED, PY21W/LED and R5W/LED based on LED technology into the Consolidated Resolution (R.E.5);</li><li> establish equivalence criteria as guidance for specifying sheets for LED substitute light source categories. (These guidelines are intended for publication, with the agreement of GRE, on the GRE website under “reference documents”, similar to criteria for new filament light sources for head lighting (GRE-77-04).

15. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) that introduce a new LED light source category for forward lighting applications (ECE/TRANS/WP.29/GRE/2017/5, ECE/TRANS/WP.29/GRE/2017/6, GRE-77-04, GRE-77-12, GRE-77-13). He explained that GTB had abandoned the concept of “thermal grade” and instead proposed the introduction of a maximum test temperature to ensure interchangeability between approved light sources from different manufacturers. GRE also noted the proposal by GTB to incorporate LED light sources into the new RID Regulation (GRE-77-14).

16. The expert from UK requested more time to study the proposals. The expert of Germany proposed modifications to the notion of “maximum test temperature”. GRE decided to revert to this issue at the next session and invited GRE experts to study the proposals and to send their comments to GTB and IWG SLR.

GRE-77-04 | GTB guidelines for introduction and evaluation of LED light source categories intended for forward lighting applications

GRE-77-12 | Revision of GRE/2017/5 (Proposal for Supplement 7 to the original version of Regulation No. 128) Updated proposal to introduce requirements and test specifications to light emitting diode (LED) forward lighting light sources.

GRE-77-13 | Revised proposal for amendments to the Consolidated Resolution on the common specification of light source categories (Revision of GRE/2017/6) Revised proposal to introduce a new light emitting diode (LED) forward lighting light source category L1. The proposal is part of a package which includes amendments to Regulation No. 128.

GRE-77-14 | Incorporation of LED light sources in the new Regulation for Road Illumination Devices (RID) Discussion paper concerning modifications to the draft proposal for a new UN Regulation on road illumination devices in order to achieve the aims of GRE/2016/34 which proposed amendments to Regulations 19, 98, 112, 113 and 123.

GRE/2017/5 | Proposal for Supplement 7 to the original version of Regulation No. 128 Proposal to introduce requirements and test specifications to light emitting diode (LED) forward lighting light sources.

GRE/2017/6 | Proposal for amendments to the original version of the Consolidated Resolution on the common specification of light source categories Proposal to introduce a new light emitting diode (LED) forward lighting light source category L1. The proposal is part of a package which includes amendments to Regulation No. 128.

17. The expert from GTB proposed to clarify inconsistencies and to correct the terminology in the 05 and 06 series of amendments to Regulation No. 48 (ECE/TRANS/WP.29/GRE/2016/24). GRE generally supported the proposals, but requested GTB, in cooperation with OICA, to extend them also to the 03 and 04 series of amendments and to submit a revised document for consideration at the next session.

GRE/2016/24 | Proposal for Supplement 11 to the 05 series of amendments and Supplement 9 to the 06 series of amendments to Regulation No. 48 Proposal to correct the terminology in paragraph 5.7.2.1. for consistency across all requirements and to clarify the language in paragraphs 6.2.9., 6.3.6.1.2.1. and 6.3.6.1.2.2. to promote the correct application of the 2,000-lumen limit.

18. The expert from OICA introduced a revised proposal with a view to defining and describing the operation of the external status indicators for vehicle alarm systems, alarm systems and immobilizers, as contained in Regulations Nos. 97 and 116 (GRE-77-25). Several experts reiterated their concerns that the proposed text, on the one hand, stated that such indicators were not considered lamps within the scope of Regulation No. 48, but, on the other hand, introduced requirements for the indicators. In the absence of a consensus on the issue, the Chair decided to postpone its consideration to the next session.

GRE-76-17 | Proposal for amendments to ECE/TRANS/WP.29/GRE/2016/33 Proposal to clarify that only external status indicators as referenced in UN R97 and R116 are addressed under the proposal to define such external indicators and introduce performance specifications under UN R48 for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers (draft Supplement 18 to the 04 series, Supplement 11 to the 05 series and Supplement 9 to the 06 series of amendments to UN R48).

GRE-77-25 | Proposal for a consolidated version of GRE/2016/33 and GRE-76-17 on Regulation No. 48 Proposal to amend GRE/2016/33 and GRE-76-17 pursuant to discussions at the October 2016 GRE-76 session:<ol><li>The direct reference to Regulations Nos. 97 and 116 that was included in GRE-76-17, para. 2.37. was removed based on the observation of the representative of Finland on a potential split, in the future, of some of the Regulations under the responsibility of GRSG.</li><li>In another remark from the representative of Finland, the word “indicator” that was missing in the last sentence of para. 2.37. in the text of the proposals GRE/2016/33 and GRE-76-17 has been added.</li><li>Based on the comments from the representatives of France, UK, Finland and Japan, the area of the apparent surface, mentioned in GRE/2016/33 and GRE-76-17, para. 5.30. <notextile>(c)</notextile> has been lowered from 50 cm² to 20 cm², in the case of one indicator is being installed on the vehicle. If two indicators are installed, the area of the apparent surface should not exceed 10 cm² per indicator.

GRE/2016/33 | Proposal for Supplement 18 to the 04 series, Supplement 11 to the 05 series and Supplement 9 to the 06 series of amendments to Regulation No. 48 Proposal to amend Regulation No. 48 following the outcome of the 167th session of the World Forum where amendments to Regulations Nos. 97 and 116 on the status indicators for Vehicle Alarm System (VAS), Alarm System (AS) and immobilizer were adopted (WP.29/2015/87 and WP.29/2015/91). The proposal aims at defining and specifying the operation of the external status indicator for VAS, AS and the immobilizer.

GRE/2016/33/Corr.1 | Proposal for Supplement 18 to the 04 series, Supplement 11 to the 05 series and Supplement 9 to the 06 series of amendments to Regulation No. 48 Correction of the proposal to amend Regulation No. 48 following the outcome of the 167th session of the World Forum where amendments to Regulations Nos. 97 and 116 on the status indicators for Vehicle Alarm System (VAS), Alarm System (AS) and immobilizer were adopted (WP.29/2015/87 and WP.29/2015/91). The proposal aims at defining and specifying the operation of the external status indicator for VAS, AS and the immobilizer.

19. The experts from the Czech Republic, Italy and Japan proposed amendments to the provisions on automatic switching between daytime running lamps (DRL) and headlamps in the 06 series of amendments to Regulation No. 48 (GRE-77-06-Rev.1 and GRE-77-10-Rev.1). The proposals received comments from the expert of the Russian Federation (GRE-77-23 and GRE-77-24). GRE realized that the proposed amendments addressed two different issues: (i) deletion of several subparagraphs that were transitional provisions only for the 05 series of amendments, but were kept by mistake in the 06 series of amendments as well, and (ii) clarification of the requirements for automatic switching from DRL to headlamps. With regard to (i), GRE adopted the proposals for amendments, as contained in Annex II, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2017 sessions. Concerning (ii), GRE agreed to establish a task force to consider this issue in detail. The experts from the Netherlands and OICA volunteered to act as, respectively, Chair and Secretary of the task force.

GRE-77-06/Rev.1 | Proposal for a Supplement to the 06 series of amendments to Regulation No. 48 The 05 and 06 series of amendments provide for automatic adjustment of lamps based on ambient light conditions. To avoid misuse of the daytime running lamps (DRL), automatic switching between DRL and dipped-beam headlamps is preferable; however, manual switching for specific cases is still necessary. Under the transitional provisions for series 05 of amendments, only automatic switching would be permissible after 30.7.2016 (for new type of categories M1 and N1 vehicles) and after 30.1.2018 (for new type of other categories vehicles). Nonetheless, in the transitional provisions for series 06 of amendments, the same transitional period appears to have been unintentionally omitted. This proposed supplement corrects this mistake in the 06 series by deleting the alternatives to the automatic switching from the 06 series of amendments:<ol class="alpha"><li>deletion of paragraphs 6.2.7.6.2 and 6.2.7.6.3;</li><li>merging and rewording of paragraphs 6.2.7.5 and 6.2.7.6;</li><li>consequent editorial adjustment in paragraph 5.11.1.3. and 6.19.7.4. to maintain acceptable the rear position lamps switching possibility allowed by the present text;</li><li>small editorial changes to better clarify that an automatic switching based on different factors in respect to those prescribed in paragraph 6.2.7.5. (new numbering) are allowed only as supplemental condition;</li><li>other editorial changes and renumbering for text and numbering coherence.</li></ol>

GRE-77-10/Rev.1 | Proposal for a supplement to 06 series of Regulation No. 48 Proposal to:<ol class=alpha"><li>delete paragraphs 6.2.7.6.2. to 6.2.7.6.3.2. concerning transitional provisions for the 05 series of amendments,</li><li>to clarify that drivers may not switch OFF the dipped-beam headlamps manually when they are switched ON automatically according to paragraph 6.2.7.6.1., and</li><li>to clarify that daytime running lamps shall not be switched OFF except as specified in paragraphs 6.19.7.1. to 6.19.7.6. (For example, DRLs shall not be switched OFF when only the position lamps are ON.).</li></ul>

GRE-77-23 | Modifications to GRE-77-10/Rev.1 (DRL switching)

GRE-77-24 | Modifications to GRE-77-06 Modifications to the proposal for a supplement to the 06 series of amendments to UN R48 with regard to switching between daytime running lamps and dipped-beam headlamps.

20. The expert from GTB proposed to clarify the requirements for tell-tales indicating a failure of different lamps (GRE-77-16). The expert from OICA introduced a proposal to update paragraph 6.9.8. with the common current technologies, where the instrument panel remains permanently illuminated whenever the engine is running (GRE-77-20). The experts from Italy, Netherlands and UK indicated their support to GRE-77-16, but were of the view that the wording in GRE-77-20 would need improvement. The experts of Germany and SAE pointed out that both proposals had a link to Regulation No. 121 and that the Working Party on General Safety (GRSG), dealing with this Regulation, should be informed. Finally, GRE invited GTB and OICA to take account of the above comments and to submit an official document to the next session.

GRE-77-16 | Updating the requirements of Regulation No. 48 on signalization of light source failure in lamps equipped with multiple light sources During October 2016, GRE-76 adopted collective amendments (GRE/2016/31) to align the requirements of lamp regulations (7, 23, 38, 48, 77, 91 and 119) to guarantee the conformity of the lamp in case of any failure or the mandatory indication that a failure had occurred. This means that when a failure indication signal is provided by the lamp, the vehicle shall be equipped with a tell-tale indicating the failure. Thus, amendments were proposed for Regulation No. 48 to specify the modes of displaying the corresponding failure (see GRE/2016/7). Subsequently, some GRE experts requested GTB to clarify the text of its proposal. This proposal amends UN R48 with respect to all lamps affected by GRE/2016/31 to include the failure indication requirement. The proposal does not apply to the failure indication requirements already in UN R 48 prior to the last (76th) GRE session.

GRE-77-20 | Proposal for a Supplement to the 06 series of amendments to Regulation No. 48 Proposal to update paragraph 6.9.8. with regard to current technologies (e.g. LED and IPS) where instrument panels remain illuminated whenever the engine is running. With the advent of new automated technologies and Advanced Driver Assistance Systems (ADAS), the number of warnings and symbols may dramatically increase in the near future. This proposal aims to reduce risks of driver confusion by reducing the number of symbols displayed on the instrument panel. The Chinese Standard GB 4094 already captures this possibility. The proposal is therefore also a move toward further international harmonization.

21. The expert from Poland, in his capacity of Chair of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL), reported on the IWG activities (GRE-77-27). GRE noted that, at its next session, it should take a decision to extend the mandate of IWG VGL.

22. GRE recalled its previous considerations of the amendment proposals to Regulations Nos. 6 and 50 concerning direction indicators with sequential activation (ECE/TRANS/WP.29/GRE/76, para. 22 and Annex IV) and resumed the discussion on whether or not these proposals would require a new series of amendments and/or transitional provisions. The expert from OICA pointed out that the proposed amendments included also installation requirements which should be moved to Regulation No. 48. To this end, he introduced draft amendments to Regulation No. 48 as well as revised proposals for amendments to Regulations Nos. 6 and 50, including a new series of amendments and transitional provisions for Regulation No. 6 (GRE-76-26-Rev.1). Following an extensive discussion, GRE was of the view that a new series of amendments was not necessary, as the proposed amendments were of clarification nature and did not introduce new requirements. At the same time, GRE agreed that the industry would need a transition period to take into account, in the design process, the amended provisions and decided to introduce them by means of a Supplement with transitional provisions. GRE adopted the proposals for amendments to Regulations Nos. 6, 48 (05 and 06 series of amendments) and 50, as contained in Annex III, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

GRE-77-26/Rev.1 | Proposal to modify the amendments to Regulations Nos. 6 and 50 adopted during GRE-76 Proposal to clarify and amend the supplement concerning sequential direction indicators adopted by GRE during its 76th session based upon document GRE/2016/20 and finalized in Annex IV of the session report. The proposal would clarify and move the prohibition against the mixing of signals of two or more activation modes to UN R48 and introduces transitional provisions.

23. On behalf of the Task Force on Electromagnetic Compatibility (TF EMC), the expert from OICA reported on the activities of TF EMC (GRE-77-21). GRE took note of the latest working draft of Regulation No. 10 (GRE-77-28) and noted that it would be officially submitted to the next session of GRE in October 2017 as a draft Supplement to the 05 series of amendments. The expert pointed out that TF EMC had identified two major changes which would require the consent of GRE: (i) change of the narrow band limit to make it consistent with the CISPR 12 Standard; and (ii) deletion of paragraph 3.1.9. The Chair invited GRE experts to provide feedback on these issues until July 2017.

See the task force status report (GRE-77-21) for an explanation of the changes and forward plan.

24. The expert from Japan provided additional explanations to their proposals for the 03 series of amendments to Regulation No. 53 regarding a new requirement for automatic switching from DRL to the headlamp (ECE/TRANS/WP.29/GRE/2016/35 and GRE-77-19). The experts from India and Italy commented on the proposals (GRE-77-09 and GRE-77-17).

25. The experts from Italy, Netherlands and IMMA requested more time to study the proposals and comments. The expert from EC recalled that this matter had already been considered at three consecutive sessions of GRE without a conclusion. He called for the establishment of a task force to tackle the issue. The experts from Japan, India, Italy, Netherlands and IMMA expressed their willingness to participate in the task force. GRE hoped that it would be able to finalize the consideration of the proposals at the next session without establishing a task force. To this end, the Chair urged all experts to study the proposals and provide their comments prior to the next 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-77-19 | Additional explanations for GRE/2016/35 (Use of motorcycle DRL at night)

GRE/2016/35 | Proposal for the 03 series of amendments to Regulation No. 53 Motorcycle daytime running lamps (DRL) can cause glare under nightime conditions (i.e., if left activated after sunset). Therefore, this proposal would require automatic switching from DRL to normal headlamp lighting as conditions warrant.

26. GRE agreed to postpone to the next session consideration of GRE-77-08 by the expert from India.

GRE-77-08 | Proposal for draft amendments to Regulation No. 53 Proposal to make the fitting of front position lamps optional and allow for its separate control under certain conditions and to allow 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.

27. No issues were considered under this agenda item.

28. GRE reverted to a proposal by the expert from GTB which aligns the conformity of production procedures with the other headlamp Regulations and which simplifies the test methods and requirements relating to conformity of production (ECE/TRANS/WP.29/GRE/2016/28, GRE-77-07). GRE agreed with the proposal and decided to forward it to IWG SLR for inclusion into the new RID Regulation (see paras. 7 and 9 above).

GRE-77-11 | Proposal to amend GRE/2016/28 (Supplement 8 to the 01 series of amendments to UN R123) Proposal to clarify that the decision table refers to the worst case situation and to correct a cross-reference.

GRE/2016/28 | Proposal for Supplement 8 to the 01 series of amendments to Regulation No. 123 During its 69th session, GRE adopted proposals to update the Conformity of Production (CoP) procedures for lighting and light-signalling devices, but decided to await the work of a GTB task force on the simplification of CoP provisions for AFS before addressing UN R123. This proposal amends the CoP procedures in line with those agreed for UN R112 (document GRE/2013/37) to create simplified photometric CoP tables for each class (C, V, W, E, R, RADB) with its applicable 0/20/30 per cent limits. Furthermore, the task force clarified which tests are necessary for CoP testing and which are necessary only for type approval testing. The methods and requirements for the "initial" type approval remained unchanged. An overview of the main AFS characteristics can be found in documents GRE-48-28 and GRE-48-30.

29. The secretariat informed GRE that the Working Party on Road Traffic Safety (WP.1) had continued discussing document ECE/TRANS/WP.1/2015/2/Rev.3 prepared by France, Italy and Laser Europe and containing amendment proposals to Article 32 and Chapter II of Annex 5 on lighting and light-signalling. At its next session in September 2017, WP.1 is expected to finalize its considerations of ECE/TRANS/WP.1/2015/2/Rev.3.

30. The secretariat informed GRE about various activities of UNECE and of the United Nations Secretary-General’s Special Envoy for Road Safety (ECE/TRANS/270, paras. 52-61).

31. The secretariat briefed GRE on the recent activities of the WP.29 Subgroup on UN Regulation No. 0 (IWVTA) and about the budgetary issues related to the development of an electronic database for the exchange of type approval documentation (DETA). GRB also noted that, in December 2016, the European Union had formally transmitted Revision 3 of the 1958 Agreement to the United Nations Office for Legal Affairs (OLA) and that its entry into force was scheduled for mid-September 2017.

32. GRE was informed that WP.29, at its November 2016 session, had requested GRE, in cooperation with IWG on IWVTA, to clarify the individual Regulations on lighting and light-signalling devices with a requirement that light sources in these devices should be type approved pursuant to Regulations Nos. 37, 99 or 128 (ECE/TRANS/WP.29/1126, para. 62). In line with this request, the expert from EC proposed collective amendments to device Regulations and to Regulation No. 48 (ECE/TRANS/WP.29/GRE/2017/7, Informal document GRE-77-30-Rev.1). Following an in-depth discussion, GRE adopted the proposals for amendments, as laid down in Annex IV, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

GRE-77-30/Rev.1 | Revision of GRE/2017/7 (Proposals for amendments to Regulations Nos. 4, 6, 7, 19, 23, 38, 48, 50, 77, 87, 91, 98, 112, 113, 119 and 123) Revised proposal to clarify the requirements for light sources in the lighting and light-signalling Regulations listed in Annex 4 to Regulation No. 0 on the International Whole Vehicle Type Approval (IWVTA) pursuant to GRE-77 discussions.

GRE/2017/7 | Proposals for amendments to Regulations Nos. 4, 6, 7, 19, 23, 38, 48, 50, 77, 87, 91, 98, 112, 113, 119 and 123 Proposal to clarify the requirements for light sources in the lighting and light-signalling Regulations listed in Annex 4 to Regulation No. 0 on the International Whole Vehicle Type Approval (IWVTA).

33. The expert from EC reiterated the importance of the Unique Identifier (UI) and DETA for the simplified lighting and light-signalling Regulations (GRE-77-31). According to him, the grouping of a number of devices into a single Regulation is not compatible with the traditional approach of using one marking per series of amendments to the Regulation. Thus, he argued in favour of mandatory, rather than optional, use of UI. GRE concurred with his view, but noted that the use of UI is conditional upon the availability of DETA. The expert of GTB also pointed out the unclear interpretation of Schedule 5 to the Revised 1958 Agreement with regard to the obligatory use of UI and DETA.

34. No information was reported on this topic.

35. GRE took note that, at the March 2017 session of WP.29, the representative of EU expressed concerns (WP.29-171-04) about the legal form of amendments relating to the heat test cycle requirement in Regulation No. 113, as contained in ECE/TRANS/WP.29/2017/39. WP.29 had decided to refer this document back to GRE for further consideration (ECE/TRANS/WP.29/1129, para. 73). GRE agreed that the underlying proposals should be introduced as a new series of amendments and adopted a revised text, as contained in Annex V. The secretariat was requested to submit it to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

WP.29-171-04 | Proposal to amend the proposal for Supplement 7 to the 01 series of amendments to Regulation No. 113 Proposal to remove the amendment to the heat test cycle related to the movement of the passing beam proposed in the draft supplement (document WP.29/2017/39). The EU views the proposed test cycle changes (based on document GRE/2016/32) as a substantial revision of the procedure amounting to a new requirement. Therefore, the EU will only agree to the proposed Supplement 7 to the 01 series if the requirement concerning the heat test cycle is removed from the proposal WP.29/2017/39.

WP.29/2017/39 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 113 Proposal to:<ol class="alpha"><li>correct provisions on bend lighting for motorcycles adopted by WP.29 as Supplement 2 (document WP.29/2012/83),</li><li>reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86,</li><li>clarify the definition of “type”, with regard to manufacturer, trade names and marks,</li><li>introduce editorial improvements to the requirements for markings,</li><li>amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45,</li><li>clarify the test cycle with regard to the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, and</li><li>harmonize related requirements across Regulations Nos. 19, 98, 112, 113 and 123.</li></ol>This proposal consolidates the regulation prior to its being "frozen" and superseded by the three new comprehensive regulations (forward lighting, light-signalling, and retro-reflective devices) drafted under the Simplification of Lighting Regulations program.

36. GRE took note that Mr. Ad de Visser (IEC) would no longer attend its sessions, due to his approaching retirement. GRE thanked him for his extensive contributions to the GRE work over many years and wished him success in the future.

37. GRE noted that the status reports of the GTB Working Groups would be presented at the next session.

38. GRE decided to keep the same structure of the provisional agenda for the next session.
