This B&O type CPL Ground Mast Signal kit can be built in many different configurations with the parts that are included. Please select your choice from the drop-down menu of signal only or signal with jig. The jig was created to help with assembly. The B&O CPL signal was configured in different heights and with varying numbers of CPL signal heads. The doll mast is also inlcuded if you desire to add it to your signal assembly. This is a complete kit including the mast and head assemblies. We recommend our 402 size LEDs.
