E53's from 00-02 had a projector fog light housing which takes an H3 bulb, made by Valeo. You can retrofit them as they bolt right up, there is a thread in the how to's and quick links by "tmv" as he posted last year about this. I had the H11 housings too but ditched them for Valeo projector housings and retrofitted an HID kit to them.
