That could be an 1156 or 7507 bulb as they are almost identical. Check the metal pin offset on the base of the bulb, if they are 150 offset- 7507. If they are 180 offset- 1156. Most likely they are 7507 as BMW changed to this bulb type sometime around 2004.
Let me know if you need any assistance in sourcing the correct bulb as well. We stock these directly
