I have a bright daylight flashing mode front light. The rate of flash is about once a second. I find lights that have faster flashing modes are too distracting. After dark, though, the flashing front light destroys my ability to see the road and I switch to steady mode. My strong light is on the bars. I also have a less bright light on the helmet so that I can turn my head and aim the light down side streets. I've considered adding a fairly wimpy flashing front light for night riding so that drivers can more easily distinguish me from another automobile.
