Fibre Flare™ Side Lights are specifically intended to be used in combination with regulatory coloured bike lights (White front light and Red Tail light) to boost your overall side visibility. How it Works?: Fibre Flare™ is a portable self contained safety device having a flexible solid core side emitting fibre optic element interposed between two electronic housing ends; inside each of the housing ends is a single high intensity LED. When the LED’s illuminate they emit a high intensity uni-directional light beam that is directed into each end of the fibre optic core; the fibre optic then distributes the LED light input and illuminates along its entire length to emit a high intensity omni-directional light output visible from almost any direction at distances over 300 meters (constant or strobe). Fibre Flare™ has integral fabric clips at either end, these can be used to fasten it to jerseys, jackets, bags etc.. As well as fastening using the fabric clips, Fibre Flare™ comes with two silicone ladder slings that slide over the fabric clip and allow Fibre Flare™ to be securely fastened to the bike frame.
