You're a man after my own heart on that one, Pimp. When I worked at AID Ambulance in Lubbock we began using low top Suburbans in the early '70s built by the Gordon K. Allen Co. of Dallas, the parent company of the short-lived Modular Ambulance Corp. The low top Suburban used by AID were equipped with four red DoRay lollipops across front of the cab with a pair of CP25 speakers in between the lollipops powered by Federal Directors, and each had the larger PAR46 Unity Spitfire beacons. AID kept the Suburbans in service until the late '80s when the state started forcing us out of low top vehicles.
You ought to see some of the TXDOT trucks that I see on I20 all the time. They're using Code 3 LED bars with amber/blue LEDs. At a distance the amber can be mistaken for red and it looks like the DPS bars I've seen recently.That's a good start, Big D. Around here, Unity RV-25's were commonly found on DOT trucks, but that was during the 70's and 80's. Beginning in the 1990's, VDOT switched to strobes. VDOT seems to be using the Federal Target Tech Turbo Flash strobe bar these days. The RV-25's are all gone.
