    a radio frequency (RF) receiver positioned at least partially within the housing, the RF receiver configured to receive RF signals from one or more sensors associated with the transport apparatus, the RF signals including information associated with an output of the one or more sensors;

    a processor positioned within the housing and communicatively coupled to the RF receiver, the processor configured to monitor the information associated with the output of the one or more sensors; and

    a visual alarm indicator positioned at least partially within the housing and communicatively coupled to the processor, the visual alarm indicator configured to be visible from an exterior of the transport apparatus, the visual alarm indicator further configured to receive power only when changing an indicated state and otherwise maintain the indicated state without receiving power,wherein responsive to detecting that the information associated with the output of the one or more sensors is outside of a predetermined limit, the processor is configured to change the indicated state of the visual alarm indicator,wherein the visual alarm indicator is configured to change state when the information from the received RF signals indicate a parameter is outside of the predetermined limit, andwherein the visual alarm indicator receives power when changing the indicated state.
