Abstract: Innovative peripheral bar assembly for a transportation vehicle is provided. One method includes retrieving, by a processor of a seat device of an aircraft coupled to a removable, peripheral bar assembly having a plurality of programmable, light emitting diodes (LEDs), configuration information to operate the LEDs; transmitting, by the processor, one or more commands to the peripheral bar assembly to operate one or more of the LEDs; and operating, by the peripheral bar assembly, the one or more LEDs, in response to the one or more commands to indicate non-verbal communication based on one or more pre-defined communication protocols indicating a seat-by-seat status.
