Knog Blinder 4v USB Rechargeable Taillight
The Knog Blinder 4V has four super bright LEDs that pump out up to 44-Lumens of light. Its optimized optics focus and directs a smooth beam pattern that makes the Blinder visible over 800 meters. With 5 different modes (Steady, Fast Flash,Organic Flash 1, Organic Flash 2, Eco flash) and a burn time of up to 3-hours in constant beam and up to 50-hours in eco-flash mode, they will keep you well seen.
This product really should get more reviews. It is very well designed. You take it off your bike and recharge it by plugging it directly into a usb port...no extra usb cable to deal with. It has a very nice clamp that is easy and very secure. Good design features aside, it is a very bright light and it is easy to turn on without taking it off your seat post. I also like that it is waterproof. I have purchased two of them in the Fall of 2013 and will continue to look at Knog products before considering others given my experience with this product.
