I ride with high vis, reflectors, and bright lights. I have two 300+ lumen front lights, so I thought that this would be enough for drivers to see me. Obviously not. At a roundabout this am and the previous friday (around 07.15), i have had cars on my left fail to stop, when I am on the roundabout. Today i really though this was it

So not wishing to become a statistic, would it help if i ran one of the lights in a flashing mode? (I have two currently, one set for the near field and one set for distance, as i ride on unlight cycle paths)
