Fog Light Switch problems of the 2004 Audi A4

I purchased a used 2004 Audi A4 in November 2007 from an Audi dealership. In the fall of 2008, both my headlights and both taillights all went out within a month of each other. I brought the car into the Audi dealership and paid for service replacement bulbs for all four lights. About a month ago, my car dashboard gave a warning that my rear left fog light went out. I have not replaced that yet, as I do not use my fog lights. Last week, I got another dashboard message that my right front headlight has dipped. The right headlight is now much more dim than the left one. Because it has been summer, I have very rarely needed to drive at dark using headlights in the past few months. I researched on the internet and found several complaints for Audi cars with dipped front headlight problems, and no resolutions or true fixes for the problem. At a minimum, it appears it will cause great expense to have the headlight fixed, only to have a very high chance of the problem recurring anyway. Several of those website referred me to this complaint form. I have not yet contacted the Audi dealer about fixing this problem, as I don't want to pay for just a temporary fix. As we now get into the fall and winter months, I am concerned for my safety while driving in the dark.
