Looking at the same thing myself at the moment.

There are lots of options

Cheap but not so effective but will get the job if she's not too fussy head lights. €300ish

Expensive but really good headlights. (Take aloof at paddy mc's thread) €800+ depending on what she wants.

Or what im looking into is retrofitting projectors and Orion v2 or v4 angel eyes into existing lights.
Just angel eyes 250-400
Angel eyes + projectors 500 - 800

All prices above are depending on what angel eyes and projectors you want because the prices vary a lot.
Have a look at light werkz

Or keep an eye on eBay for genuine replacements but usually they arnt cheap.
