There are a few option:

-Upgrade headlight wiring and fit better halogen bulbs, Osram night breakers or something similar

-Retrofit a crappy H4 HID kit which will have a beam pattern all over the place

-Ebay has plenty of cheap headlight housings with clear lenses, search 7x6 or H6054

- Roguesystems did offer a twin headlight replacement unit but the link I had saved is dead

-Retrofit a proper HID unit into a 7x6 headlight housing but that requires a lot of work
