Hi posted this question in another thread and got no responce maybe the wrong place. I have a Broncolor Impact lights with 2 #21 heads and 1# 41 head. One of the 21 heads dose not flash, I placed a known working flash tube and it still did not flash. Is there someone that still services these lights? Can you still get parts for them? Broncolor dose not service them anymore, they say there to old. Thanks
