    Default 2007 Buick LaCrosse low beams

    I had a low beam headlight go out last year so I replaced both with sylvania silverstar ultra H11ís. They didnít last long so I replaced them again with the same thing, went out again and then read on the back of the package they were only rated for 150 hours. My low beams are also my daytime running lights so they are always on.
    I'm looking at Phillips H11 X-treme vision. They have 300 hrs run time.
    I work nights, live in the sticks so my drive home is in the dark and drive in during winter is dark.
    Any recommendations? Led upgrade that isn't too expensive?

    Good on replacing the complete pair, rather than just doing one at a time. Not so good on the bulb selection, unfortunately. Sadly, marketing is so much more effective than their bulbs.

    They didnít last long so I replaced them again with the same thing, went out again and then read on the back of the package they were only rated for 150 hours.
    They're rated for such a short life because the filament changes required to make such a blue-tinted bulb still produce the legally-required amount of light will severely shorten the bulb life.

    I'm looking at Phillips H11 X-treme vision. They have 300 hrs run time.
    Philips X-Treme Vision doesn't play the "let's tint the whole bulb" game, and therefore has a filament that may be shorter-lived than a standard bulb, but will greatly outperform it *and* outperform the SilverStar Ultra.

    Any recommendations?
    It might be time for new factory headlamps-- the 10-to-11 year old lamps you have may have outlived their usefulness. You might also need to do a voltage drop test (see here) because the wiring may also have degraded. Whether you get new lamps or not, be sure to aim them correctly.

    Led upgrade that isn't too expensive?
    Unless the '07 LaCrosse (or a sister car) had an LED option (in which you could just buy that model headlamps and install them), no. There are no LED "upgrades" for headlamps short of taking a different complete LED headlamp unit and attaching it to the car, or removing the composite headlamps and attaching the likes of JW Speaker or Truck-Lite "sealed beam"-shaped LED replacement lamps (which could make the car look rather goofy, but would be safe if you attached them securely enough and aimed them properly).

    (In your previous post, I had to edit a bunch of color tagging and "viglink" tokenized URLs. If you copied this post from a post you'd made on another message board, be advised many of those 'other' boards will take keywords and make links out of them to try go get hits from unaware people.)

    You really have to decide whether you prioritize long bulb life or the best possible vision at night; you can't have both at the same time. As Alaric says, there is no legitimate "LED upgrade" for your headlamps. All such (claimed) products are unsafe and illegal -- no matter what the seller claims. Do not be fooled. Same goes for "HID kits".

    The best-performing H11 bulbs available now are this GE type or this Philips type (at half the price, being the better value). Either of them will have a short life relative to a lower-performing standard or long-life bulb, but you'll get to see better at night.

    And yes, the headlamps need to be in perfect condition (no lens haze/fog/other degradation) -- if they are not, replace them. Use only genuine GM lamps (left, right), because the aftermarket/off-brand ones are junk.

    Also, whether the lamps and bulbs are new or old, they must be aimed precisely. They're the "VOR" type, as described here.

    Thanks for the replies, I ordered the Phillips and will see how they work.
