External Led & Buzzer

I am coming back to the arduplane from 2.73 where I feature froze and I saw this external LED Indicator with a buzzer on an arducopter a friend was running. I am wondering if the equivalent of the LED Mode setting on 3.3 exists? I have not been able to find it.

The last time I looked it wasn’t supported in APM:Plane, shame as it would be a great little feature.
