That was the newer or second generation of the bar. That one did not have that smart rotators option. That was only in the first generation of the light, and the rotators were positioned behind each other, (not angled as shown) The reason is originally, it did not have separate flashers. That came later on.
I know what everyone is going to say.... IDC. I have been through these bars for the last 35 years. I know what they came with from factory.
Now I do have an original bar for sale, but the control board was removed
