I own several of them and have been very happy with them.But they suffer from a few shortcomings. First, they have a short repeat sequence. Drunk and high-on-drugs drivers can get mesmerized by such a sequence and will run right into a light like this like a moth to a flame. So I've been using the superflash on the sides, not the back. Second, they are very bright up close, but from a distance, with lots of...

Best tail light I've seen
This light kicks ass, super bright and a great random flashing pattern. Drivers may confuse you with a cop that has pulled someone over. Expect wide berths from passing cars.
