7.85 Data Element: DE_LightbarInUse
Use: A data element which is set if any sort of additional visible lighting-alerting system is currently in

Used to reflect any type or style of visual alerting when a vehicle is progressing and transmitting DSRC
messages to others nearby vehicles about its path.
