    Yeah my roommate's cts has it and the lights seem kind of dull. I figured it was because the bulbs are 5 years old. It's an 08.

    These cars are still an amazing value. I just saw a spotless white N* at $16K. I only paid $5k more almost 5 years ago with like miles now! Go price an equally featured car; find one?

    you are just pointing out the resale value...

    Your statement is accurate

    Though...if you look at it from the other side of the coin

    if you bought one of these new( or very early) in its life it would have to be about the worst value among its competitors

    I had a cts with it. They sucked. The light output is no where near the sts lamp output especially with intelibeam.
    when I was testing driving cars years ago

    As I recall the Infiniti M35 had the lights that turned with the car and I thought it was a very neat safety feature. I think it also had HID high beams..unlike the STS

    did they ever put HID Hi beams on the STS's?

    Negative. Most cars I've ever seen do not have dual beam hids as they would surely take a beating with flash to pass.

    The xlr and dts has a single beam and to activate high beams the Hid light has a switch. When you activate high beams the low beam bulb adjusts its angle and projects higher thus high beams without the flicker.

    Well, this is also true of the Buick Enclave. Although, it sounds to me like there is a shutter assembly that is raised when the high beams are activated. I've never dug into one of these headlamps so I can't say for sure, but that's sure what it seems like.

    This is just a movement of a cutoff shield. The lamp and projector do not move at all.
    There is a solenoid that is used to pulldown a shield on the bottom of the projector to expose more of the HID lamp thereby creating the high beam effect.
    Low beam only HIDs only use about 50% of the light from the lamp, the other 50% is blocked off by the same shield but in these lights the shield doesn't move.

    ok...how do the other manufacturers do it?

    Hi beam HID's have been around for years
    it looks to me when the light are on hi beam and they are not HID( while the low beams are)...the yellower vs whiter light looks odd

    Please show me a car that has HIDs for high beam that isn't using a bi-xeon projector. I bet you won't find any. HID lamps take too long to reach a usable intensity to be used as high beams on their own. HID lamps and ballasts also don't last long in the rapid on and off that high beams get.

    I have an xlr lamp I can't give away. I plan on taking it apart to see exactly how it works before I pitch it.

    Re: difference between STS4 1sg and Platinum Edition STS?

    Here is an example of a bixenon D1S projector from Valeo ... likely the same projector that is in the XLR/DTS

    You can see in red on the left there is a soleniod that moves the large flap towards the camera / projector lens and exposes more of the lamp output.

    Here is an example of just the shield removed from the housing ... this particular person is modding the shield to create a flat cutoff instead of the stepped cutoff that we know so well.

    thats my point...why didnt they use Bi-Xenon projectors on the STS?

    I think every other car I can think of had them other than the STS( that was equipped with HID)

    Why didn't those other cars stack dual projectors? Why does the cadillac have vertical taillamps? Other cars I know don't have those. I have a feeling we might be thinking too deeply into this one.

    you are talking styling vs functional features

    two very different things

    I have driven a car with bi-xenon and an active headlight system

    believe me..both make a difference when driving down a dark road

    I think both are features that were picked on the new XTS

    I guess so. I do alright with the halogen high beams. Maybe their desire to put in two projectors drove them to the halogen high beams is what I'm getting at.

    I completely agree that having a bixenon HID setup is really beneficial at night.
    I have done headlight projector retrofits in 3 cars in the last few years changing them from halogen high and low to using a single bixenon HID projector that made a world of difference.

    The SRX also did dual projector headlights.

    I think cost and style were the reasons here.
