+1 on Light & Motion. I've had the Solo for several years of winter commuting and love it....for taillights I have a couple of older $10-$15 5 light blinkies. I think 2 really makes a difference -- the differing patterns get the attention and the 2 makes depth perception easier for folks behind you.

I got a planet bike superflash for my partner -- WOW they are bright. Will probably add one to my collection soon.
