PROPOSED SPECIFICATIONS OF RED AND GREEN NAVY SIGNAL LIGHTS (Revised)

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.
