I just ordered 4 of these for an install I'm working on for a funeral home. They're pretty incredible little lights, however, when running dual color, there's no option for "off-time" between light heads. All of the lights will be on simultaneously. From my understanding, this is typical with Code 3, specifically with the MR6.
The owner of Wicked Warnings has a light that he private labeled as the "Razor." It's the identical light that he most likely purchased a significant quantity of and had his label put on it. His lights do have off time when running dual color and there are a few additional patterns that are sync'd.
