Not sure about the brake peddle switch as the brake lights works fine. Bulbs are correct placeand correct wattagebulbs the wrong way round (if they are dual filament)
or a sticky brake peddle switch
I get drivers flashing me, and they look very bright.Why do you think the lights are (too) bright?
The W204 does, indeed, use trickery to reduce the brightness of the tail lamps in normal running. Under normal circumstances, the car runs the 21W tail lamps at reduced voltage / brightness.My conclusion is either the data is wrong or the car uses some electrical trickery to reduce the brightness of the tail lamps vs the brake light.
The trickery has two functions to deal with bulb failures: In the event that a brake lamp bulb fails, when operating the brakes the tail lamp bulb in the same cluster runs at full voltage so that you have a brake lamp on both sides of the car; similarly, if a tail lamp bulb fails, the brake lamp bulb runs at reduced voltage so you still have a tail lamp showing in the same cluster.
In addition, if the car is in reverse and the reversing lamps are illuminated, when you operate the brakes the regular bake lamps illuminate, and the tail lamps also illuminate at full voltage making the overall brake lamps brighter so they are still visible “over” the white reversing lamps.
I had a W204 saloon which had issues with the rear lights. Have a look at the plastic connector as, the 204's burned out and gave a useless Earth. This cretaed one side brighter than the other.
Mercedes know this is an issue but refused to treat it as a recall.
