A control device for a first motor vehicle, and for dimming lights for vehicles ahead and/or oncoming vehicles during turning maneuvers includes a first interface with a recognition device for the purpose of recognizing vehicles ahead and/or oncoming vehicles, a second interface with headlights, wherein the control device selects different light distributions of the headlights and generates an adjusting signal at the second interface for adjusting the selected light distribution at the headlights to dim the headlights if a signal is present at the first interface indicating at least one vehicle ahead or oncoming. The control device has a third interface for indicating the start of the recognition of a turning maneuver of a vehicle ahead, wherein the dimmed light distribution of the headlights remains set for a predetermined distance or a predetermined time if the signal is present.
