Buy a HID Upgrade Kit,
i got mine installed for about £120, which included the part, i have the ICE Blue headlights along with the sidelights and full beam.
This was done in bradford but im sure u can pickup what you need on ebay for about £70, and you can DIY this job very easy!
They add the awsome look like the range rovers and merc and that, good cheap upgrade and Lots of extra visability
