Review prepared by the Task force on Substitute and Retrofit Light Sources chair.

Amended version of the proposal to GRE to introduce requirements and test specifications for light emitting diodes (LED) substitute light sources under UN R128.

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 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 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.

General observations from Germany concerning all documents related to “LED substitute light sources”.

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

The regulation of lighting includes individual regulations for specific lighting devices (headlamps, direction indicators, etc.), for light source (filament, gas, LED), and for installation (UN R48). The proposed UN R0 on the type approval of whole vehicles requires submission of approval certificates for components and systems to be included within the whole vehicle approval. Vehicle manufacturers work directly with UN R48 approvals, but lamp and device approvals are generally handled by lighting suppliers. UN R48 includes provisions for listing approvals of lighting units, but not for approvals of light sources (presently UN R37, R99, and R128). In order to avoid excessive administrative burdens, GTB proposes that the regulations covering light units include provisions to confirm their approval under the applicable light source regulations such that UN R48 approvals would represent approval of the vehicle lighting systems under both device regulations and light-source regulations.

1. introduce provisions for LED substitute light sources into Regulation No. 128;
