    Replacing the bulbs sounds worse than it is. Took me about an hour. Seems easiest to to one side at a time, in other words do not remove the entire front valance from the car.

    bigtone could explain just a little how to do one at a time, ( can the whole lens be removed doing one side at a time? ). Would you be able to take the lens inside you're home and change all bulbs you're way? Sorry if the questions sound silly but I've never had to replace mine yet, just being informed and ready when I have to thanks.

    It really is not that bad. I did it without even taking the wheel off I actually had to take the passenger side off twice to change the ballast. Had it in and out in 37 minutes.

    If you just loosen one side of the valance, you do not need help removing it entirely off the car. There is enough flex in it to pull it away the 6 inches or so that you need to remove the light assembly itself. If I remember, after valence is out of the way, 3 bolts (all 10mm) is all that holds the light assembly in. I did not remove the wheel either. There is a good writeup with pics that helped me as far as finding the bolts by feel. Do a search.

    Re: TSB For Flickering Headlights

    My right HID headlamps on my 2006 DTS has started turning off randomly. sometimes it will flicker a couple times and stay off. If I manually turn off the headlamps and then back on, it will usually stay on again for awhile. Some nights it will stay on without flickering. The headlamp is still bright, but definitely has a pink tint to it. It's not visibly flickering more than a couple times.

    I've read online about bulbs and ballasts and from what it seems like to me, is that it's time to replace the bulb, but if I wait longer the bulb flickering could get worse and cause the ballast to fail. Does that seem like a fair assessment? The ballast is awfully expensive and I'm hoping that if I replace the bulb now, while it's just starting to go out, that maybe that will save the ballast. Can anyone offer some advise?

    Do the front wheels need to come off, or can they be turned out of the way? This determines whether I can do the job myself. I don't have a jack and don't want to buy one.

    The wheels do NOT have to come off. Just change the bulb, once you have done this it is much faster the second time if you need to do the ballast later. When you see your ballast see if it is made in France or Germany. Mine is made in Germany, I think I read on a thread that the 2006,2007 have the French and 2008 and up have the German and they are trouble free.
