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.
