haha nah not replacing the whole headlights just the bulbs. Was considering either Philips or Osram. Looking at the reviews I went for the Osram SilverStar, they seem pretty popular.
Can't personally comment on the Osrams, as I've always used Philips, and been very happy with the quality (unlike Lucas bulbs, which are truely shocking in quality!)
I personally use
www.PowerBulbs.com, as they are one of the honest, "no-bull", and well-established internet retailers, who also have physical stands at various motorshows and events.
These are the LED rears I was talking about:

From the listing they seem to be for our car. Although looking at the Pic the outer light seems to be a different shape
They look lush, and they are definately the boys for the Mk5, as the 1K0 bit of the part number proves. And if they are made by Hella, then they will be "E" approved, and OEM quality, so will be perfectly legal. My only concern would be to check they are simply "plug and play", or would they need re-coding in the relevent ECU, due to the different current drain, which will affect the bulb monitoring in the MFD.
Oh, and make sure you get the correct sides for fog and reverse lamps!
