There are many styles of light fixtures that could direct the light where you want it. Some are ceiling mounted, others wall mounted. Decide where you want to put a light and how you'll run the wiring. A 12v LED light could probably be piggy-backed on the wiring from the present light, or in lieu of the old fixture.
