Interesting, I had tried to find them on Sylvania's site without success. The original examples I had seen looked alot more 'normal' than your second link, and actually used a halogne bulb for the high beam, instead of a Bi-Xeon light source, so in that regard it looks like the first link you posted may be an updated version.
Certainly a better way to go than fitting an 'HID Conversion' bulb to a Halogen headlamp system.

Found a link
to an article dating back to 2002 regarding the original Sylvania 7" round HID replacements I had seen, just for kicks..
