Here is a generic 4 head warning stick. Built very much like the Whelen Dominator series. Guessing a Twain knock off. Surprised that it is as bright as it is.
Looks a lot like one I bought off here a year or two back in a dual head version, Red/blue. Extremely bright and lots of useful patterns. Not cheap junk imo. If these are one in the same maker I recommend this light.
