I appreciate your input on the Cygolite 350. By all accounts it seems to be a very good light. I also ride reflective ankle straps, day, and night, as well as a reflective green vest.
Here's the thing, there are many MVAs that have occurred in broad daylight, where visibility was not an issue. Simply put, stupid people do stupid things.
I will agree with what others have said, that more visibility does seem to get me more respect on the road, especially at higher speeds.

Bottom line, while increased visibility helps, it's not the be all, end all. ALWAYS maintain situational awareness (whether mirror or radar), and have an exit strategy.

Ride safely!
