Motor Vehicle Headlight Having At Least Two Light Modules

A motor vehicle headlight, that includes a main-light module that provides a dipped main-light function having a mainly horizontal cut-off line and a secondary light module that provides two individually controllable light functions: one main-light function and one less powerful additional light function. The dipped main-light function of the main-light module is activated in conjunction with the additional light function of the secondary light module, such that the at least one secondary light module appears to be illuminated approximately as brightly as the main-light module. The secondary light module has a light guide plate into which light is coupled that propagates in the light guide plate using total reflection, and the light guide plate has output elements for outputting the propagating light from the light guide plate. The light output of the light guide plate illuminates an area above the cut-off line of the dipped main-light function of the main-light module.
