A method for fault monitoring at a lighting output of a motor vehicle. Reference current values are first measured and calculated at various reference voltages. During operation of the lighting output, operating current values and operating voltages are measured. If the operating current value at the measured operating voltage deviates from the reference current value at the corresponding reference voltage, then a fault message is output. The method is suitable for detecting a fault even for unknown lamps at the lighting output.
