On a somewhat related note, how many LEO's here have/had a vehicle
where they could turn off one headlight if they felt the need?
I know of two around here over the years, one was a driven by our
local Conservation Officer and the other was a local Twp Cruiser.
I've done some ride-alongs with our local Twp and the last I knew
they had the ability to prevent their brake lights from coming on.
