hids4u retrofit bi-xenon kit advice needed

the above link is for a H4 bi-xenon kit.

my car is a 1999 a3 1.8t sport (pre-facelift obviously), it has 3 bulbs: 1 sidelight, 1 dipped, 1 main/fog bulb, so im using a H4/H7 combo, so i looked at this kit instead: http://www.hids4u.co.uk/product_details.asp?id=332 which is the standard xenon fit with a choice of bulbs. however the blurb for it says:

We dont recommond this kit for the H4 fitting as the H4 bulb is only Xenon for dip with a small separate halogen bulb for main. We recommond the HIDS4U Pro Bixenon kit unless the car has separate main beam lights.

..so the first part they dont recommend this std H4 xenon kit because its for dipped xenon with halogen main beams (which i have?), but then right after they recommend the bi-xenon kit unless the car has seperate main beams (which i also have, but the bi-xenon is 2x H4 fittings, not 1xH7, 1xH4 that i require).

based on the contradicting/confusing info they've provided, what sort of kit do i need/want?

(argh!)

also whats the difference between a "projector style" headlamp and a "standard reflective headlight" look like, how can i tell the difference as apparently std reflective headlights can be converted, whatever that means?

Basically you need the H7 kit. It will work OK in the standard lights, but facelift units are much better as they are projectors, not reflectors.

any way of changing the pre-facelift lights to be projectors instead of reflectors (without having to buy an expensive new headlight unit, assuming they fit)
