A system for a vehicle that includes a movable chassis and an operator station rotatable relative to the chassis. The system includes a sensor, an indicator assembly, and a controller. The sensor can detect an orientation of the operator station relative to the chassis, and generates a signal indicative of the orientation of the operator station. The indicator assembly is disposed on the operator station, and includes a first indicator indicative of the operator station oriented in a first direction, and a second indicator indicative of the operator station oriented in a second direction. The controller is in communication with the sensor to receive the signal indicative of the operator station orientation from the sensor, and further is in communication with the indicator assembly to selectively vary the indicator assembly between the first indicator and the second indicator based on the signal indicative of the operator station orientation.
