If your light doesn't blink, you blend in with the surroundings. The blinky aspect makes you stand out and that's the whole reason for a light. This is not an opinion, it's fact. If your tail light doesn't blink, it's not as good, period. Get a Planet Bike SuperfFash. It's all you need. If you want more, get 2. You will get nothing better, you can get brighter, but not better.
