After years of dealing with a finicky front interior dome light in my 380SEC, I finally decided to tackle the issue. A careful teardown revealed dirty electrical terminals and a few misplaced components—including a tiny ball bearing my daughter luckily spotted. With some cleaning, soldering, and strategic reassembly, the switch now functions flawlessly, clicking firmly into place. Reinstalled in the car, the light works exactly as it should—no more pressing or fiddling required!
