I'm from Hialeah....so I had to pause for a minute before responding.
I think you are referring to the JetStrobe bars. I have never seen one on an FHP car, but I guess it's possible. Another possibility is that the Jetsonics could be ordered with optional strobes, housed in the normal takedowns (the later style). These were a direct plug and play type of installation, and could easily be made to function without any additional wiring (ie, easy for a Trooper to make the modification).
