Other Vehicle Electronics Standards cover rotating electrical machines (motors) for rail and road vehicles, starter motors, technical documentation of electrical and electronic systems, lamps, switching devices, and other vehicle electronics standards. This collection of topics serves to complement the previous categories, bringing to light smaller areas of standardization that do not normally receive as large of a focus. These standards relate to light sources.

IEC 60809 Ed. 4.0 en:2021

Lamps and light sources for road vehicles - Dimensional, electrical and luminous requirements

IEC 60809:2021 is applicable to electric light sources 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 fourth edition cancels and replaces the third edition published in 2014, Amendment 1:2017, Amendment 2:2017 and Amendment 3:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Introduction of a light technical measurement on LED light sources intended for use in front-lighting applications. b) As the original data sheets and some figures from previous editions were not available in an editable format, they have been reproduced from their old format, following the current drafting rules and are now in single language format. Some reproductions constitute minor (obvious) editorial changes of the original text sections and original figures; no technical changes were introduced.
