The headlights were probably a custom job using his original headlights. I bet they took apart the light and put in HID projectors/bulbs/ballasts and maybe shrouds too and then put tint or paint over the original amber.
I googled and found a couple of places that do custom headlight retrofits:
http://www.customlightz.com/
http://hidtech.com/ click on "retros"
The prices they have listed are around $300-$400, however neither lists Boxsters, but you can email them for a quote.
Doubt any of it's DOT legal, but looks good anyhow.
Good luck,
