Remarks: The value of zero SHALL be used when an unknown elevation must be sent. The Elevation

7.22 Data Element: DE_ExteriorLights
Use: The status of various exterior lights encoded in a bit string which can be used to relate the current
vehicle settings.
The "Vehicle Exterior Lights" Probe Data Element provides the status of all exterior lights on the vehicle.
As currently defined, these are: parking lights, headlights (lo and hi beam, automatic light control), fog
lights, daytime running lights, turn signals (right / left) and hazard signals. Should the need for additional
types of light be needed, a new data element will be added.
