I've never owned a light that I couldn't point down. Even $3 DealExtreme junk lights have an angle adjustment.
If you want a real quality light, keep in mind that the Cygolite Hotshot is not only a ridiculously powerful, excellent taillight, but the brightness is very adjustable, down to quite dim, and would also be great for your purpose as well as cranking it up for solo riding.
