I've never seen a CFD vehicle with a Firebeam. But they use so much, someone could have had one. I've seen PowerArc dash lights, visor flip downs. For years when the Highlighter came out, all the big bosses' cars had a clear dome Highlighter on the rear deck. The rotators were green & clear. There was a red filter over the middle mirror.Did they truly use these, and in this color combination?
Here another example of an East German rotating beacon. The FER 8562.1 was produced from 1963 till mid of 70s.
