That converted Zed looks familiar .. :roll:
I priced all this up for someone a few weeks back and if you have halogen then £700 is closer to the mark for a complete pair of light units. For Xenon around £1500, assuming you already have xenon for the ballast, bulb, and connectors.
Your 2.2 will also likley have black inners so for the same price you can switch to silver as fitted on 3.0. On some it looks way better.
Ask Mike says cost rise if you want to match side repeaters, brake lights and third brake.
Add anything from £400 to £1000 to change the bumper cover.
