so... can anyone comfirm for me what bulb fitment the prefacelift has, H1 or H7? 
If they are the same as facelifts........H1 mate

I have to agree with MDTM on this one........Retro fit HID's (can only comment on projector headlamps) definately make an improvement......so much so.....i used to hate working in the dark.....now im fine with the darkness.
re the blinding other drivers........ive had lots of times when other drivers have dazzled me with HID's......in nearly new cars......so can only summise...their auto dipping isnt as good as it should be.....so whats the point of it!
re the washers........ive found the light level does drop with HID's when the lense gets dirty.......but probably about the same as Halogens fitted.......a rag is better than water jets to clean em

Oh and noticed in a post by MDTM........that manu's use different headlamp units for Halogen and HID's so shouldnt be swapped.......
However i have checked myself a bit.......and confirmed by TB.......its unlikely vx use different projector units for HID's and halogens.....
