Light bright and easy to use

This is a great little light that really puts out a lot of power. If you want to turn it down a bit, there is a flashing mode which alternates between pairs of LEDs. It clips on and off the bike easily. On the down side, you will probably need a USB extension cable, and the switch can be a bit fiddly in the dark with gloves on. I have only had this for a week, I have had the front version for about a year now, and is going strong.

Great lights

These lights are fantastic. Their power to size ratio is fantastic. They are easy to fit as the battery life on charge is excellent. To give an idea of brightness they light up road signs as you approach them. Overall an excellent purchase!

Knog blinder is a blinder

Super bright. Easy to charge with green led to denote completion. Super build quality and only time will tell as to whether or not the rubber strapping stands the tests of time and British weather. The rear is not suitable for aero posts.
