The same... these are just the brands, then you need to check if your car uses H1, H3, H4, H7 bulbs etc and buy the correct one for your car. E.g. Osram NightBreaker Plus H7.
The standard headlights on the 639 are pretty good. Unless someone has put cheapo bulbs in yours?
Philips XTreme significantly improved the SL and the Audi but made no difference that I could tell on the Vito. It was a fiddly job changing them, too.
