1. A method for operating a headlight for a motor vehicle, said headlight comprising a plurality of light emitting diodes, the method, comprising:
receiving a request signal for a high-beam mode;
determining a road class of a roadway on which the motor vehicle is located;
activating a first group of the plurality of light emitting diodes for providing a first high-beam distribution with the headlight in the event that the road class is different from a highway; and
determining a structural separation between lanes of a highway and activating a second group of the plurality of light emitting diodes for providing a second high-beam distribution with the headlight by activating the second group of the plurality of light emitting diodes in response to determining the structural separation in the event that the highway is determined as the road class.
