Cessna 172 Stall Alarm
This is the Stall Alarm of the Cessna 172
This is taken from this YouTube Video: • Wing stall alarm (Cessna 172)
Even though it's from an Infinite Flight Video, it's legitimate, it is not fake. This is confirmed in a Cessna 172 cockpit video (I couldn't find it now), it contains a half-second stall alarm that matches the one in the video.
