Lighting system for commercial vehicle, has signal path extending from light control unit to opening elements for transmitting opening signal, and shift element comprising support function and arranged in signal path

摘要

The system has a signal input for inputting function data for light units present in vehicle lamps (L1-L3) i.e. LEDs. Load simulation units (41, 42) and opening elements (31, 32) i.e. transistors, are arranged in an electric circuit (S). A signal evaluation unit (15) recognizes whether the electric circuit is in an open condition or a closed condition. A signal path (S1) extends from a light control unit (10) to the opening elements for transmitting an opening signal. A shift element (30) having a support function is arranged in the signal path.
