I've got one, but don't use it much because 1) I'd rather have just one light on the bars, and 2) I usually ride my dynohub-equipped bike when I'm just tooling around town.
It's legally ambiguous, though, as laws regarding bike lights only refer to white in the front and red to the rear. But, I don't think that legality should be a problem.
this would depend on where you live and the traffic by-laws regulating what can and cannot be used as lights.
one would have to look it up for their state/province.
personally, I wouldn't buy amber because white works just as well in daytime and can be used at night time as well.
for maximum night time visibility, green works really well, much better than amber.
