I bought my 2008 C350 used last year. Ever since I have had it, the interior lights have always gone off and one or dim down and then brighten back up the entire time I have them turned on, or when the door is open, etc.. That is all of the interior lights, including map lights dome light, etc. Any idea what may be causing that? It's kind of annoying when you want to read something in the car at night, etc. Thanks for any suggestions.

Might be the light sensor on your car (the sensor that detects wether it's night or not) do the head lights turn on when this happens? If it doesn't it might be an electrical problem.

No, the headlights work exactly as they should. I also don't have any faults and it always works exactly the same way. I don't have any errors, faults, etc.

It might also be a electrical problem, I've never experienced or heated of issues like this. Maybe try changing out the car battery? you should also take it to your nearest dealer to find out what they think.

Did you ever solve this problem? My 2009 has developed this exact problem now.
