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.

Proposal to correct HIR2 headlamp data.

Changes to the proposal to introduce LED light sources into the lighting installation Regulations Nos. 48, 53, 74 and 86.

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.

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 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.

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).
