摘要

The vehicle has a high voltage electrical system that is laid in the vehicle based on two-wire lines (L1, L2). A set of plug devices forms ends of the two-wire lines. The plug devices are arranged such that an optically perceptible signal is delivered by the plug devices depending on voltage at the corresponding end of the two-wire lines. The plug devices deliver the signal when the voltage exceeds a limit value. The signal is produced based on thermochromic effect independent of the voltage.
