Brake Light problems of the 2001 Mercedes Benz SLK

I am an owner of a 2001 Slk 320. I have had chronic problems with headlamps and brake lamps going out , bulbs melting in lamps on brakes as well as headlamps. In the beginning these repairs were paid under manuf. Warranty. However, I am paying for replacement bulbs, most recently a headlamp problem I will have to have replaced at a cost close to $600. Today I received a recall from mercedes notice for the brake lamp problem. I question that the same may be true of headlights. My condition of brake and headlights being replaced as well as a brake lamp replaced in the past, was so chronic, I ordered and paid out of pocket for electrical testing on my car where nothing wrong was discovered. My point here is that I feel in addition to the brake light problem addressed by mercedes in my recall # 2006-080005, I believe it would be remiss for safety purposes to not announce that I believe the same condition applies to my Slk headlights. Also, for such problems on the brake lights that existed in the past, what recourse do I have in monies I laid out of pocket, pertaining to the chronic brake light problem in my Slk 320. Thank you.
