Hi there,
I was thinking axactly the same - smked rear and sides etc. But once you make the initial jump and go for it - its not that bad. They do look very good!!!
Well Im very happy with them. I bought these of ebay for ?95 (+ ?7 p+P). I know you can take a risk with what you buy off ebay but I saved a lot of money than if I was to buy them from a high street shop. I asked the guy loads of questions before hand and he had thousands of good feedback from other satisfied buyers so I thought what the hell!!!. They are In-Pro, Brand new, with bulbs, delivered within 2 daysand took me about 10-30mins to fit. Just unscrew the four screws and the plug socket o the back to take off your old ones and then reverse the procedure for fitting the Mk4 styled ones.
Depends on your personal taste but for me personally they do look excellent and I am glad I took the jump and bought them - if I can get a picture for you I will. But I believe there loads of pictures of Mk3's with Mk4 lamps here on this site - thats what swung it for me! And I am well pleased!!!!!!

Good Luck!!!

Happy New Year!!
