Very cool pix all, thanks...

Eden, from a drivers viewpoint, the best cyclists at night are the ones with a flashing light AND a steady light on the front. The flashing one is def the most visible, I know it is a bike, and I never mistake it for a tin or road marker like I have with one steady light.
