Must agree with you, op is probably looking for something more specific like parking brake will cut out lights via a micro switch, lights are commonly Bosch on most German built vehicles. Also somewhere between the headlight switch and the lamps is a headlight relay which can also be bad. Even still a 2011 vehicle is subject to bulb renewals by now. Just look at some VW Beetles after 2 years, common to be "one eyed jacks". I had two, common pain of operation.
