    STS 2007 Headlight problem !!


    The headlight on he driver side won't work at all , also its a lil bit foggy. I have asked to replace it and they cost too much.

    should i replace the hole kit or just buy a light and replace it ?

    is there anyway i can fix it instead of paying that much. I live in Texas , so please if anyone can tell me another solution of doing it.

    thanks so much

    I'm guessing you're talking about HIDs? Either way, you should solve the condensation problem before changing the light. Google search "cadillacforums sts headlight condensation". There are so many threads about how to solve this issue. Once that's done, change your halogen bulb or hid bulb.. Whichever we're talking about. If HID, and changing the bulb doesn't work, change the ballast. I would say it is not normal for HIDs to have gone out on your 2007 already so it's definitely related to the condensation if it is in fact HIDs we're talking about.

    Yeah, if they're HID it's related to the condensation, they should've lasted longer. My 06 still burns the factory D1S bulbs as bright as can be.

    Both of my headlights went out within about 3 months of each other. I found out the cost of replacement and decided to do it myself. I'm not very handy, so it took a few hours to complete, but it saved me about $200. I watched this video: and it explained exactly how to complete it. The tools you'll need are a flat-head screwdriver, a socket wrench, I believe a 10mm socket, a 10mm socket extension. I don't have a good jack, so I couldn't jack up the car, but doing so may help. The flat-head is to pop off the tabs which are a bit of a pain. You'll only need to remove one of the bolts underneath each wheel well, you can slide the bumper off of the other. Hope this helps you too.
