Or more exact: can xenon housings be used with regular halogen bulbs if you don't have stuff like ballasts, autolevellers, and xenon bulbs? Or will that not work?

the halogen bulbs will fit. Some people have trimmed the H7 base a little to let the bulbs sit more flush but the bulbs do work. Just make sure you seal up the ballast hole well (so no moisture gets in) and secure the inner housing by either using a shipping plug from euro xenon housings or rigging up some kind of contraption in place of the auto levelers

When you have xenons, the xenon bulb connects to the ballast. But if you don't have ballasts, where do you plug in your low-beam bulb and do you need to buy a harness for that?<ul><li><a href="https://forums.audiworld.com/a4/msgs/1683553.phtml">https://forums.audiworld.com/a4/msgs/1683553.phtml</a</li></ul>
