    Abstract - (Show below) - (Hide below)

    Colour of light emitted by signalling equipment. Includes performance requirements for plastics filters and a new method of presentation of data for both glass and plastics filters.

    Scope - (Show below) - (Hide below)

    This British Standard specifies the colours of light signals for all purposes. While it has been based on requirements for transport signalling it is equally applicable to signal colours for other purposes, e.g. indicating lights.

    Guidance on means of achieving these colours and of maintaining the performance of signals is also provided.
