This document is applicable to electric light sources (see Note 1) for use in automotive applications, for example in road illumination devices and/or light signalling devices for road vehicles.
It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject to other legislations.
This document specifies the technical requirements for interchangeability for example dimensional, electrical and photometrical characteristics, and includes test methods.
For the light sources listed in this document, the data sheets are contained either in this document or are included by reference to UN Resolution R.E.5.
Performance requirements are specified in IEC 60810, for example life, torsion strength, resistance to vibration and shock.
The requirements for miniature light sources for supplementary purposes, not subject to legislation, are specified in IEC 60983.
NOTE 1 The terms "lamp" and "light source" are both used in this document to mean the same product, so the two terms are interchangeable throughout this document.
NOTE 2 In various vocabularies and standards, different terms are used for "incandescent lamp" (IEC 60050845:1987, 845-07-04), "discharge lamp" (IEC 60050-845:1987, 845-07-17) and "LED lamp". In this document "filament lamp", "discharge lamp" and "LED light source" are used, however, where only "lamp" or "light source" is written, all light sources, independent of the technology used, are meant, unless the context clearly shows that it applies to one kind of technology only. In the UN Regulations, the word "light source" is used for the products specified in this document.
NOTE 3 Wherever the term "device" is used, it is meant to designate equipment which is used as a luminaire. It can for instance take the form and purpose of a headlight or signal light.
