On my 01 I bought very nice light assembly foe about $220 for the pair.

I had HID so I had to transfer over from my old but I did a similar refresh on an 08 328 that had halogen.

I tapped power for the halo off the O₂ sensor heater. They are on any time the engine is running. I used a random ground just find a bundle of brown somewhere.
