Road vehicles -- Symbols for controls, indicators and tell-tales
This standard has been revised by ISO 2575:2010
ISO 2575:2004 establishes symbols (i.e. conventional signs) for use on controls, indicators and telltales applying to passenger cars, light and heavy commercial vehicles and buses, to ensure identification and facilitate use. It also indicates the colours of possible optical tell-tales, which inform the driver of either correct operation or malfunctioning of the related devices.
