I'm in favour of anything that increases my chances of being visible to drivers when I head out for the early morning commute, dorky or not!

In fact, I'm waiting for my order to come that is a whack of items to do just that - front light, rear light, the reflector things for the valves, a reflective triangle to put on my backpack, ankle strips, etc. etc. I suspect that by the time I get myself and my bike all decked out with those things, I'm going to bear a marked resemblance to a Christmas tree on wheels...

But, I'd rather be a visible dork, than the alternative....
