I have seen the light , fitting my Xenon HIDs
Not sure if this will help any one but this is how I fitted my new Xenon HID lights , I got these of Ebay , £55, 6000k slim ballasts , with no fancy packaging stating that they are 300% better than halogen blah blah , no nice glossy picture of a Zonda , just well packaged in cardboard boxes
I started on the drivers side first by taking of the cover to get to the headlight bulbs , connected up as per instruction and checked that all is working and your new lights are shining bright .
Now look for somewhere to stash the ballast , I have put mine on the brackety thing that holds the bumper on , (donít know the technical term for anything , sorry ) .
I attached with some double sided sticky pads and a cable tie , hopefully this will hold and I will check it at the weekend again to make sure every thing is still there .
