Headlamp having a circuit assembly for simulating a load current from a vehicle electrical system

A headlamp for a conversion of an original headlamp of a vehicle, the headlamp having one or more light functions, the headlamp comprising:

• an input for each respective light function of the one or more light functions, wherein each respective input is configured to connect to a line of an on-board network of the vehicle,
• an output configured to connect to the on-board network of the vehicle,
• a module for simulating an original load current for each of the one or more light functions that require significantly less power in the headlamp than a corresponding original light source in the original headlamp,
• wherein each respective module comprises an electronic converter, a series circuit arrangement of a resistor and a switch, wherein the resistor is rated to a comparable order of magnitude of a resistance of the original load current to be simulated, and the series circuit is connected in parallel with the input,
• one or more light sources each having an associated electronic operating device for each of the one or more light functions of the headlamp, and
• a controller for controlling each respective module and for controlling the one or more light sources
• wherein the module is configured, upon activation of at least one of the one or more light functions, to open the switch and turn on the electronic converter and, upon deactivation of the at least one of the one or more light functions, to close the switch and turn off the electronic converter,
• wherein the one or more light sources are configured to be switched on after a specific time interval following closing of the switch.
