Not sure if the cheaper ones above are real Valeo lamps...
Xenons say genuine, but the halogen ones dont...
Stapo, you should be able to fit the projector and ballast etc from your pre-facelift lamps to a halogen set, but its quite a bit of hassle to take the lamps apart!
I would be tempted to buy the xenon ones above, and buy a D2S bulb/ballast kit from hids4u, should work out quite cheap, assuming they are real valeo lamps!
