Shrink, can you pm me the email of the author? I'm having a set of standard headlights converted to HID and curious what "refurbished" means. Is this a 3rd party company that retrofits new ballasts, bulbs, and projectors or does it mean Tesla has a bunch of old / 2nd quality HID kits that they're selling at a discount. Thanks!
As for exasperating the clear lens from the body, be very very careful. I couldn't do it myself, the company who're working on my HID conversion didn't know if they could separate it either but they did succeed.
The price to have my headlights converted to HID was estimated to be $550, will have to see the real cost once they're finished with the prototype and have it fully completed. The LEDs look really wild in the night pic from the conversion above!
