Fog Light Switch problems of the 2005 BMW 330

Over the last several years, the light intensity has steadily declined in both headlights of my car, to the point where they no longer function. My mechanic has looked inside the headlights and found that the projector bowl reflector has prematurely worn out -- it has lost its reflective ability. According to the mechanic and based on multiple reports in online group discussions, this is a known issue with these zkw xenon headlights. This defect in the headlights compromises safe operability and increases the risk of a night-time accident. This is a part of the headlight that should not wear out or need replacement under normal operating conditions, as has been the case with my vehicle. I have resorted to using my fog lights or high beams for driving at night. BMW and zkw are deflecting the issue. I would like to request an investigation regarding a potential widespread defect in these xenon zkw headlights. We should not have to wait for an accident to correct the problem.
