I also run the Superflash on my seatbag as well as the Mars2.0 on my rear rack. On the front I run two lights, one flashing one steady. One lbs guy ragged me good about these flashing lights until I told him how I ended up practically under someones front wheel. Then he understood my cautions.
You have to assume you're not registering with drivers unless you add some weird attention-grabbing elements. Even then, I still have drivers & peds who just don't see bikes on the road, they're so tuned for car-shaped things.
