Motor vehicle headlight having at least two light modules

A motor vehicle headlight having at least two light modules, which is designed to provide at least one dipped light function in a light-emitting direction of the headlight, said motor vehicle headlight comprising:

• at least one main-light module for providing a dipped main-light function is designed having a substantially horizontal cut-off line,
• at least one secondary light module designed to provide two individually controllable light functions, to emit one main-light function and one less powerful additional light function,
• wherein to provide the dipped light function of the headlight, the dipped main-light function of the at least one main-light module is activated and the main-light function of the at least one secondary light module is deactivated or only activated in such a way that the at least one secondary light module appears darker to an observer than the at least one main-light module when viewed towards the emitted light of the headlight without activation of the additional light function of the at least one secondary light module,
• wherein the additional light function of the at least one secondary light module is additionally activated to provide the dipped light function of the headlight, such that the at least one secondary light module appears brighter to an observer looking towards the emitted light of the headlight than without the additional light function,
• said at least one secondary light module includes a light guide plate for providing the additional light function, into which light guide plate at least one light source, which is not used to provide the main-light function of the at least one secondary light module, couples light, which propagates in the light guide plate because of total reflection, the light guide plate having light outputting elements for outputting the propagating light out of the light guide plate via a light-emitting surface of the light guide plate, and
• wherein the light output of the light guide plate illuminates a region above the cut-off line of the dipped main-light function of the at least one main-light module.
