In the time since my last post in here, I have acquired a Whelen Liberty, a Federal Signal Streethawk, and a Federal Signal Vector SL and Mini Vector SL and more recently, a Federal Signal Vista.
I do not have the Arjent, Streethawk or Vector SL anymore, was able to sell them. The Mini Vector SL I made into red white and blue, that full size Vector SL needed a new power control cable, I had one on hand, installed it and was able to sell it for twice what I paid for it.
The Liberty I bought off of Ebay 5 years ago was all blue with halogen takedowns and alleys, I have since made it red and blue with LED takedowns and alleys as well as Wecan(computer programmable) I am currently waiting on a lens kit which will give it colored lenses. I might then find a Wecan Duo TA board and add in some RA/BA Duo modules to the rear.
My Vista I got this past weekend but I need to replace the strobe controllers.
Addition edit:
Just got a lens kit for my Liberty today, looks much better
