Yes, Flash Technology is one of many companys that use Burst & Flash Chokes in their Beacon sysytems. The Beacon systems consist of many capacitors, relays, High & low voltage Transformers, Circuit boards and these chokes.I was unable to find any information to these chokes on their site or any other web site to give a better understanding of their use in the system. My guess is that they control the capacitors somehow limiting the output of the capacitor.
