You can easily customize your configuration to blink the LED on such events using the LED section of the dashboard and be notified (obviously the game needs to send enough telemetry data to support these flags or warning info).

Some devices like the Leo Bodnar SLI-PRO allow to wire external LED in addition to FLAG LED.
