On my commute, there is a road that has a lot of cross streets that people use because they are shortcuts. As long as they don't stop for stop signs, they are faster. Every night I there is someone flying up to a stop sign just at the right moment that they haven't seen my headlight. That's why I always have a helmet light. And nobody stops for stop signs around here ether, so it's really dangerous. I was thinking about all sorts of side visibility lights, but I don't think any of them will work as well as a helmet light in the face.
