Scope

This document applies to electric light sources in road vehicle lighting devices and/or
light signal devices (see Note 1).
It is particularly applicable to light sources listed in UN Resolution R.E.5 and light
sources subject to other regulations.
This document specifies the technical requirements for interchangeability, including
dimensions, optoelectronic performance, as well as corresponding measurement
methods.
For the light sources listed in this document, their leaflets are either included in this
document or refer to UN Resolution R.E.5.
IEC 60810 specifies requirements for light source life, torsion strength, vibration and
impact resistance.
IEC 60983 specifies small road motor vehicle bulbs for auxiliary purposes that are not
covered by regulations.
Note 1: In this document, the terms "bulb" and "light source" refer to the same product, as these
two terms are interchangeable in this document.
Note 2: In different vocabularies and standards, different terms are used for "incandescent
lamp" (845-07-04 in GB/T 2900.65-2004), "discharge lamp" (845-07-17 in GB/T 2900.65-
2004), "LED lamp". In this document, "filament lamp", "discharge lamp", "LED light source"
are used. However, when only "lamp" and "light source" are written, it refers to lamps of these
three technologies, unless the context clearly indicates that it is used to refer to lamps of a
certain technology only. In UN regulations, the term "light source" is used for products specified
in this document.
Note 3: "Device" in this document refers to equipment used for lighting purposes. For example,
equipment used as headlights or signal lights.
