Around here that's a no go for law enforcement in their POVs, but (volunteer) fire fighters often deck out their trucks (never seen a car...hmmm) in a similar manner, red lights only, with their department/rank on a plate that attaches to the front of the license plate. I've seen then warp factor 9+ a couple of times past my parents' place in the boonies.
