    V1 vs. V2 headlights - something worth quibbling about

    As someone who's lovingly stuck with the V1 (but admittedly drooling over the V2) something occurred to me the other day...

    On the V1, the low beams are at the top of the headlights and highs are at the bottom, on the V2 it's reversed (I'm presuming the arrangement of the V2 are the same as the 09CTS).

    I definitely like the V1 better because the arrangement just seems more unique, those HIDs being right at the top of the hood just look menacing at night. (The only other vertical stack I can think of is the prev gen G35, and I think those were the same arrangement).

    Why would they have reversed them for V2?

    Maybe I'm just consoling myself psychologically with reasons to keep loving my V1 in the face of the coming V2....

    I think you're right.

    There's several differences between the Sigma and Sigma2 CTS headlights, mainly that the new ones are Bi-Xenon, and use the same bulb for high and low beams (a motorized reflector in them changes the angle). The new headlights also turn up to 15 degrees with the steering at night, looking through the apex of a corner before you enter it, which is really neat.

    From a cosmetic standpoint, I assume that they moved the bulb to the bottom of the housing to reduce the "tall" look of the first CTS (a critique that more than one reviewer has mentioned in the new CTS articles). Which one looks better is just personal taste, but I think the new ones look awesome at night.

    The low beams on the 2004-2007 CTS-V are HID. The separate high beams are not HID (standard halogen bulbs). Cadillac Tony is correct in that the 2009 CTS-V has only one lamp for both high and low beams with the low beam results from a mechanical shutter. However, I don't think the 2009 CTS-V lamp is halogen. It is HID as it was in the 2004-2007 CTS-V series.

    Im lost. Noone said the new V would have halogens? Theyre bi-xenon...

    Xenon is a halogen gas. The 2008 CTS-V does not use a halogen bulb with a tungsten filament for the headlamps. The 2004-2007 CTS-V always had HID low beams. The new CTS-V will have HIDs also, but there will be only one lamp with the low beam being produced by a mechanical shutter. The standard CTS might use non-HIDs. As an example, earlier STSs had a headlamp that outwardly appeared to be an HID, but was actually a halogen bulb with a tungsten filament.

    Xenon is actually a "noble" or "inert" gas that is ionized by the electric arc in an HID capsule; traces of Iodine, Bromine compounds, etc. make up the "halogens" in a halogen lamp.

    Youre sorta right here. But HID systems do use xenon gas. HID bulbs contain xenon gas and metal salts. An electric arc ignites xenon gas very quickly, which gives off some light before the metal salts ionize and produce the really bright light. This is why typical HID systems look like they take 1 or 2 seconds to light up fully.
    Technically these are metal halide lamps, but its common to call them xenon bulbs in the car industry. MErcedes uses a similar setup, like the 09 V, and still call it bi-xenon.

    You're both wrong- Xenon gas is actually from the planet Xeno, and creates light when microscopic alien nanomachines are activated by the stalk mounted lever inside the car.

    Seriously.

    So why doesn't the 2009 CTS-V come with a collector dish to gather trace particles of xenon gas to keep the navigational sensor array... I mean the headlights charged? You'd expect that on a $70K car, right?

    What a ripoff. I'm buying an M5.
