ABSTRACT:
An optical signal emitter assembly emits light pulses which are received by an optical traffic preemption system detector. The optical signal emitter assembly employs a honeycomb element positioned in front of a light source which collimates light emitted by the optical signal emitter assembly. The optical signal emitter assembly is convertible from a stand-alone unit containing power supply circuitry, timing circuitry, and a light source in a single housing, to a unit wherein the light source can be mounted independently from a housing containing the power supply circuitry and the timing circuitry.
