I referenced this thread to Mark VIII.org, days later a member posted that he had finished testing these replacement units.
You can take this with a grain of salt, or as legit. He had no photos, but that may be from an NDA (non-disclosure agreement). The units have been returned to Ford.
He claims they are completely new housings that use standard halogen bulbs.
This is good news or bad new, depending on how you look at it. New housings mean the cost will be high, probably in the ball park of $600 or more. Since they use standard halogen bulbs, options for after-market kits, cheap ones, haven become endless. The sky will be the limit for HID conversions! Also, if these were new housings WITH HIDs, think of the cost of this kit, it would surly be a lot more.
Worst case, you have to shell out some cash. For NEW updated housings made from better plastics that should be made right - not yellowing/fading.
Best case, Ford starts a silent recall exchange program where one can bring in the vehicle for minimal labor charges to have the old housing removed and new installed. But that probably wont happen unless the DOT is on their butts about this.
