Hi, The LVAR INI_LIGHTS_BEACON_SWITCH is constantly changing and although is is a boolean LVAR the value is constantly being changed.
The value rapidly changes from the name of the aircraft loaded. in this case "AIRBUS A350-1000", and "STATE_PUSHBACK_BEGIN".
Screenshot of the data monitor of the LVAR.
It shows 805 number of changes without activation of the switch.
