A control circuit controls at least one lighting device in a vehicle, preferably in a motor vehicle and includes at least a first output channel and at least a second output channel. The first output channel is adapted to provide a first maximum current, and the second output channel is adapted to provide a second maximum current. At least the first and second output channels are suited to be combined into a third output channel, wherein the third output channel provides a third maximum current. The third maximum current corresponds to the sum of at least a share of the first maximum current and at least a share of the second maximum current.
