Here's a video of the light I have. It flashes really fast. At night, to a driver looking in their rear view mirror, it can very easily appear to be an emergency vehicle (police don't always use their sirens BTW.) Next time you're in your car look in your rear view mirror and see how difficult it is to make anything out at night. I don't think the same thing applies to rear blinkies since cars are approaching from behind have a good view of what is ahead of them. Although I prefer a slow blinking rear light in the dark as well.
