Road traffic lights — Photometric properties of 200 mm roundel signals
The visibility of a road traffic signal depends on many factors, the most important of which are
the colour, luminous intensity and luminous intensity distribution of the light.
This Standard deals with the colour, luminous intensity and luminous intensity distribution for
200 mm road traffic signals. The serious problem of sun phantom, which can affect the correct
recognition of the light, is included in the Standard.
Reference documents relating to the colour of road traffic signals are detailed.
