Our 2006 R350 had all the tail lights burn out at the same time resulting in a safety issue. There appears to be a common issue with this model and year with a wire harness that controls the rear brake lights. When this harness fails the tail lights stop working. Mercedes knows about the issue and has a TSB on it, but will not cover repairs if the vehicle is not under warranty. There are multiple complaints on online mercedes forums regarding this defect.
