Abstract: A headlamp for the conversion of an original headlamp of a vehicle, comprising: an input for each light function provided by the headlamp, wherein the input is configured to connect to a line of the on-board network of a vehicle for the associated light function, an output for connecting to an on-board network of the vehicle, a module for simulating a load current for those light functions that require considerably less power in the headlamp than the corresponding light source in the original headlamp, at least one light source with an associated electronic operating device for each light function of the headlamp, and a controller for controlling-the modules for simulating a load current and for controlling the light sources with the associated electronic operating device. The module for simulating a load current for each light source comprises a series circuit arrangement of a resistor and a switch.
