I don't think color matters so much on the spoke lights; they're going round and round and that's what speaks "bicycle here!"
(I have had 'em all at some time or another. Oh, and you can put one 2032 battery in there and it does as well as the two 2016 that are stock; our bike project sells 2032 for a dollar so I do that).
Lane position is pretty important, too...
You can do lights much much cheaper -- a five dollar flashlight and rubber bands... a head lamp from a camping store... rear blinkies are a little harder to come by, tho', and IMHO they're really important.
