Can a ceiling fan light kit be installed WITHOUT a fan? i.e. directly to the ceiling?

I have found a great light fixture, but it is meant to be installed as a light kit on a ceiling fan, not as a stand-alone ceiling fixture. Can I install it alone, without a fan, directly to the ceiling? How do I know which wires to cap/ignore and which to use?
Update: Wiring is old but okay, circa 1929, plain fixture (no fan) was in place previously.
Update 2: The wires I'm wondering about capping/ignoring are those on the new light -- it seems there are extra for connecting to the nonexistent fan.
