The car currently has a set of Depos on it, and the back covers are missing. The wiring has been well and truly butchered and the bulbs don't lock into the light cups or anything.
I have bought a replacement set on eBay from another S3. Unfortunately it looks like he has had halogen bulbs in them. The lights take a H1 bulb so I will try and get a set of these in Xenon flavour.
Are both dipped and main beam supposed to be Xenon on an S3?
It looks as though the wiring has been chopped to add facelift headlight connector plugs as my car has these. If I plug them into the Depo lights, they come on fine and work as they should. Unfortunately I have also got an aftermarket HID kit fitted and some on here have speculated that this may be because the original ballasts packed in.
I have seen items on eBay that claim to be replacement ballasts for the OEM items.
How can I find out if the car still has the OEM ballasts? Where would they be? And if I have them (or if I replace them), would I be able to swap out the halogen bulbs inside the new lights for Xenon items and have everything work fine with just the main headlight plug connected? The current setup has a ballast with wires going directly to the Xenon bulb in addition to the other plug (which again, is butchered).
I think my Mrs would rather run halogens on the car with lights that aren't messed up than keep the current setup!

Seems to draw power from this butchered headlight plug:
