In the Aztec I fly, you can actually hear the relay driving the stall
light
clicking on and off when you're on the "hairy edge".

I always hear it when I do the pre-flight. (From the front of the left wing
you can look in the cockpit and see the light go on when you lift the stall
warning switch) But I've never tried to listen for that clicking during
stalls or on landing. Next time I go up, I'll give it a try.
