I have a 100 lumen blinking tail light and a 600 lumen up front that can be dimmed or blinking. I blink it during the day and run it on dim for the most part at night. When I'm not on the road and mixing it up with traffic, I shut off my front light. I'm not worried about other bikers, hikers, skateboarders or what have you seeing me, just vehicular traffic. I also don't aim it directly into oncoming traffic as that is just being obnoxious, yet most vehicles see it, especially at intersections. With my blinking up front my incidences of being cut off when I have the right of way is much lower. I still ride like I expect people to be stupid and self absorbed.
