Your MY has a proprietary bulb that was designed by BMW. It's not a traditional bulb size like H8 like the E92/3 has.
Just google LED angel eye bulbs for pre lci e90. You can tack on your MY as well if you want.
The bulb has holes for a long torx bolt on either side. It won't look anything like a normal bulb.
