[Water Warrior 2]

Interesting innovation but I wouldn't go for that at all on my bike if I was still pedal pushing. The best in my opinion is the tried and true flashing LED's that fit on front and rear. Add a couple more to sides and be visible . Always on even when you stop at a stop sign, red traffic light or in an alley. You can move them to another bike too. Bonus there. Visible during the day as I have noticed during my trips up and down the roads. 4 rechargeable batteries and you are good for years at less cost.
