To those who ride in the dark, what do you do about side visibility? My taillight provides some, but not so the headlight. I wear reflective ankle bands, but that won't cut it if a source of light doesn't hit them.

I was considering clipping one of these to each ankle (or possibly wear the bands on my arms, instead):

or these ones:

Any suggestions, thoughts? I don't like the fact that I'll look like a X-mas tree, but, at least I will be a safer X-mas tree than a less than visible cyclist.
