Abstract
A three color aspect light signalling system that displays one color at a time without producing phantom signals. The apparatus utilizes three sources of collimated white light, a filter and two dichroic mirror/filters are used to produce three colored aspects and two output lenses are used to collimate the colored output signal so that it may be seen at distances greater than one mile.
