Embodiment Construction

[0023] figure 1 A schematic diagram of an overall module 1 for a vehicle is shown, which provides load current simulation for the most important light functions. The overall module 1 is composed of different individual modules. However, the overall module can also be designed as a separate module which contains all functions. Currently, the overall module 1 consists of a load module 11 and a resistor module 12 .

[0024] Load modules are used for load current simulation of larger consumers, such as searchlights or turn signals.

[0025] The resistor module is used for load current simulation of smaller consumers, eg license plate lighting.

[0026] The two modules work differently.

[0027] The load module 11 has a cold lamp monitoring device 110 , an electronic load 112 and an LED retrofit lamp monitoring device 114 . The cold lamp monitoring device 110 is used here to simulate a cold lamp in the off state. Electronic load 112 generates a load current on the input leads...
