The document deals with photometric properties of stationary signal lights for road traffic. Minimum-values for the luminous intensity are stated, according to the dimensions of the signal light and its colour. Requirements concerning the uniformity of the signal lights luminance are also given, together with maximum values for the reflectance properties in order to limit phantom light effects.
