Optical signal emitter assembly

摘要: An optical signal emitter assembly (20) emits light pulses which are received by an traffic preemption system detector. The employs a honeycomb element (40) positioned in front of source (36) collimates emitted the assembly. is convertible from stand-alone unit containing power supply circuitry (32), timing (34), and single housing, to wherein can be mounted independently housing circuitry.
