If you convert to Euro units for the clear corners (which my car has BTW), you will want to buy the correct pair for your car (Halogen bulbs or Xenon).

Realoem can be a good guide, naturally select the Euro version of your car with the same build month and year as yours. Selecting EUR and LHD will avoid most issues, then pick Halogen or Xenon.

Ebay.de can get you good and bad parts, as Ebay.com, so know what you buy in advance.
