Firstly, I have scoured the threads looking for a similar issue and have not some up with anything. I bought my 2006 C55 AMG a couple of week ago to replace My 2001 E55 AMG. I am happy with the car for the most part. However I am having exterior lighting issues that are beginning to make me regret my purchase. Her is a list of issues with things I have done to troubleshoot the issue.

1.) Passengers side rear lights do not work at all. None of them, brakes, turn signal, reverse lights or running lights. I have checked all the lamps and the check out fine, I swapped the light plates from passengers side to drivers side. The problem did not follow the plate. The plate from the passengers side worked on the drivers side. I hooked up a separate ground w.ire thinking I had a bad ground but it did not correct the issue. Put everything back to original and now neither side brake lights work, the center one on the trunk does work. Neither reverse lights work now. the only lights working are the rear drivers side running light, and rear turn turn signal. I am getting no lighting errors from the CAN BUS when i start the car.
2,) I have the right licence plate light out too but I haven't even checked the lamp in it yet. No warning from CAN BUS
3.) Both front turn signals don't work. I haven't even checked the lamps yet. No warning from CAN BUS
4.) The low beams lights work perfectly except when I activate the turn signal in either direction. Then the drivers side low beam blinks off for a second then turns back on for a minute then blinks back off, Again no warning from the CAN BUS.

Any help or pointing me in the right direction would be very much appreciated.

Are any of the bulbs LED?

No I don't have any LED Bulbs

Update I replaced the Xenon Bulb that was blinking when the turn signals are turned on. It did not correct the issue.

Correction all the drivers side rear lights work except the brake light.

Check your rear sam for corrosion

Everything runs through computers on these cars, this is both good and bad. If you have access to a scantool that can read these systems diagnostics becomes trivial, plug in, read codes, follow diagnostics procedures in service manual/alldata. I got my C55 not long ago and had some issues with bulbs and bulb warnings. I must have removed my tail light electric panel at least 5 times hunting various bulb problems.

I'm in Oregon and I have such a scantool, where in Washington are you? I travel to Seattle area fairly regularly and can help you out.
