A motor vehicle body has at least two sills running laterally in a longitudinal direction of the vehicle. The light emitting diode comprises a plurality of light emitting cells two-dimensionally arranged on a single substrate. In accordance with one implementation, the new trusted core is allowed to access only selected application data previously securely stored by the current trusted core. The waveguide is surrounded by air on three sides for improved heat isolation. Furthermore, the other of the second or third USB-terminals is connected to the second device-terminal via a third circuit.
