Abstract:

Specifications for signal lights a They must not impose undue manufacturing difficulties. b Colors must be distinguishable at small subtense. c A compromise must be made between the brightness of a signal light and the purity of the hue. d They are influenced by the number of signal lights that will be employed in a given system. e Distinction must be made between lights which will be employed for high visibility as opposed to those which must be distinguished unerringly. f Certain signal lights will be used with reduced voltages which change the color of the signal.
