    Rated 4 out of 5 by from stylish and compact rear light very stylish and compact rear light with nice features i bought this rear light for my partner to use on the back of her helmet although not designed for this purpose i successfully fitted it to the helmet thanks to the flexible bracket the various quirky modes on these knog lights make you more noticable to road users so it is an excellent addition to the standard rear light on her bicycle

    Rated 5 out of 5 by from Red Rear Originally I thought that this light might not be as effective as the front led how wrong was I since I have had them I have had 2 car drivers who happen to be keen cyclists ask me to stop just so they can get details of the light and where they can get them
