Today while out grocery shopping, I was on my way home when I came across an active police scene, in this group of cruisers was a next community over Tahoe, I only saw it from the rear, It had what I am pretty sure was a Whelen Legacy with a pattern I have never seen before on a lightbar, the bar was half red half blue, the pattern was a side to side alternating fade on fade off without completely turning off. Is this a pattern that can be found in Whelen Control or could it belong to a full control car controller box? Car was obviously in parked mode so maybe it only does this when in park.
