Abstract

A lighting device of a vehicle is provided. The lighting device comprises a light fitting, which comprises a first and a second light source with different color locations. Furthermore, the lighting device has a first sensing module, which senses the actual value of the color location of the light fitting. In addition, the lighting device comprises a set value generator module which presets a set value for the color location of the light fitting, and a control module which reduces the difference between set value and actual value by means of an actuator module. Here, the set value of the color location of the light fitting is dependent on a driving situation of the vehicle or a personalized driving setting.
