Seeing that flashing lights on bikes are illegal in Europe (right?), I've been running my lights on steady. But maybe the European law(s) are based on lack of research. What do I know?
What do you think is more effective, and why? I'm starting to think that flashing is better in the day time. I'm sure a steady headlight is better in the night, but I'm not sure about a tail light.
I'm about to head out into a very foggy day, and it seems to me that a flashing tail light is more likely to keep me alive.
