Double Projector Headlamps

[gavins]

My 2006 C2 came with the bi-xenon headlamp setup. This has a xenon upper bulb sitting behing a projector lens and an electronic shutter that re-directs the xenon beam when you switch between lo and hi. The headlamp unit also has a normal halogen bulb sitting below the projector lens, and surrounded by a large reflector. The halogen bulb comes on when you select hi beam.

The other day I saw a 997 with headlamps that had TWO projector lenses, one upper and one lower. The difference was very clear to see as, instead of the large reflector housing the normal lower halogen bulb, there was a second projector lens in its place, making a total of two projector lenses. I did not take a photograph but does anyone know what this setup is? Just to be clear, the normal 997 xenon setup has a xenon upper bulb sitting behind a projector lens, and a halogen lower bulb sitting in a large reflector. The setup I saw had TWO projector lenses.

If I see it again i will post a photograph but i am curious to know if this is a model year change or some other option.

The headlight design is changed from one lens on 997/1 to two lenses on 997/2 and further subdivided in a fixed and a dynamic cornering (option) version, here directly from the book: Bi-Xenon headlights offer advantages BOTH for DIPPED beam and HIGH beam headlights. Hope it helps.
