Proposal to introduce a new light emitting diode (LED) forward lighting light source category L1/6. The proposal is part of a package which also includes amendments to Regulation No. 128. 2. GTB proposes one category L1/6 with “maximum test temperature” 65 °C. The definition of the maximum test temperature is necessary to ensure interchangeability between approved light sources from different manufacturers. A separate (unique) light source category is specified for every “maximum test temperature”. The choice of installation of a light source with a given maximum test temperature is based on the application in the vehicle and determined by due diligence of the car maker and set maker, in the same way as is now the case with LED modules.

Proposal to introduce new light-emitting diode (LED) substitute light source categories C5W/LED, PY21W/LED and R5W/LED. This proposal is part of a package which also includes amendments to Regulation No. 128.

Proposal to correct a reference to standard IEC (pursuant to a change in paragraph numbering of the IEC standard) and to align UN R37 with UN R48 and UN R128 with regard to the use of the term “chromaticity area”. The wording “required tolerance area” in case of colour is changed to “required chromaticity area” to align with Regulation No. 48. This proposal was initiated by a proposal to amend Regulation No. 128 aimed at avoiding confusion with other tolerance areas.

With the publication of Revision 8 of Regulation No. 37 and the subsequent adoption of the Consolidated Resolution on the common specification of light source categories (R.E.5) (ECE/TRANS/WP.29/2016/111), light source experts and users of light source Regulations have made the correct linkages between the Resolution and third party documents. This proposal corrects a number of minor editorial errors in sheets of filament light sources that were discovered while making such linkages. The proposal further includes a number of customary administrative updates of International Electrotechnical Commission (IEC) cap sheet numbers in the IEC cap sheet references.

Proposal to introduce requirements and test specifications for light emitting diode (LED) light sources for forward lighting.

Proposal to introduce requirements and test specifications for light emitting diodes (LED) substitute light sources, including to

1. introduce provisions for LED substitute light sources into Regulation No. 128;
2. introduce new category sheets C5W/LED, PY21W/LED and R5W/LED based on LED technology into the Consolidated Resolution (R.E.5);
3. 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). In addition, these criteria are being prepared for insertion in publication IEC 60810.);
introduce equivalence reports for the new categories C5W/LED, PY21W/LED and R5W/LED in LED technology (see GRE-77-02).

Proposal to update the definition of “stop lamp” (in line with similar definitions in UN R7 and UN R48) so that it would allow the use of different stop lamp activation methods for powered two-wheelers (e.g. by the application of a retarder or a similar device). A corresponding proposal for amendments to Regulation No. 78 (GRRF/2017/14) has been submitted to the September 2017 session of the Working Party on Braking and Running Gear.

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.

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

Proposal to re-insert paragraph 5.11.1.3. with regard to switching between headlamps and DRLs. Although GRE agreed to delete this and related paragraphs during its 77th session (see para. 19 and Annex II of the 77th session report), the Task Force on Headlamp Switching decided upon further review to retain the possibility to switch ON DRLs in conjunction with at least the rear position lamps without the need for the position lamps tell-tale in that case.

Explanation of changes between the proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86 presented at GRE-77E/2017/4) and the revised proposal (GRE/2017/22) submitted for consideration at GRE-78.

Request for guidance regarding interpretation of UN lighting rules:

1. Is it allowed that the shape of the apparent surface can be the logo of the manufacturer brand or other brand-identifying figures?
2. Is it allowed that the shape of the apparent surface can be the same as an evocative/suggestive figure? Even as an informative figure such as road traffic
   signs?
3. Is the advertising lighting allowed at the national level in the Contracting parties, regarding to its influence on road safety and distraction?
4. Do we have to consider an apparent surface, whose shape is the logo of a brand manufacturer or other brand-identifying figures, as a advertising lighting?

Request to delete the amendment to paragraph 3.3.4.1.1. in the proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices. The proposed amendment was included in the submission by mistake.

Proposal to address inconsistencies, clarify text, and correct terminology in Regulation No. 48:

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23.

Proposal to reinsert text in paragraph 1.3 concerning differentiation of types according to trade name or mark that was inadvertently omitted from Supplements 27 and 28 to the 01 series of amendments.

Proposal to align the draft Supplement 20 to the 01 series of amendments and draft Supplement 2 to the 02 series of amendments to UN R53 more closely with UN R48. These supplements concern the use of different stop lamp activation methods (in alignment with similar provisions for four-wheeled vehicles).
