FIBRE FLARE

Regular bike lights light up brightly in a one primary direction
(uni-directional), and generally work well for traffic approaching from
behind you, but what about traffic coming from the side and other
angles? Meet Fibre Flare,
the worlds first truly omni-directional bike light, it allows cyclists
to be seen from all angles and directions rather than just from the
front or rear. Available from amazon
