In some embodiments, the cable can also transmit signals to the high voltage assembly or the bulb assembly or both.

The cable may be used to transmit direct current, and may also be a control bus, e.g., a CAN bus, to be able to transmit control signals to the high voltage components and/or the bulb assembly and/or other components or drive modules of the OTS, e.g., the motion control unit and/or the bulb assembly, etc.
