i purchased them off ebay last year, after fitting and driving around you just dont get the same light output effect as standard lights give..
maybe its just me but the lights just seemed more dull and fixed without any spread like on the sides or anything compared to normal headlamps/ so i sold them on.
Iv heard the HELLA XENON LOOK headlamps are ment to be the best aftermarket upgrade from standard halogen.. They look exactly the same as the xenons and guessing the light output will be near enough the same but with manual adjust you wont get it perfect.
Oh and yes they are a plug and play fit, well mine was anyway, no mods needed.
