Signal Type Mast Color Light Colors
(all the same)
There are some other configurations of light colors available. Signals are supplied from Custom Signal Systems. Please contact them for custom projects such as different signal types, light colors, signal bridges, etc.

Diodes may be required to work with the Signal Override if you do not want to use a three color signal with the red, yellow, and green outputs. In that case the unused cycle needs to be merged with one of the other cycles otherwise the signal would be dark.
