Dryer notification idea

I'm looking for a small light up button or something I can use so my wife can see when the dryer is done. I'm going to use a vibration sensor. And was thinking of a small led sign but looking for other ideas also

I use an ESP32 with a KY037 sound sensor. It’s triggered when the room’s noise goes above 39db for over 10 minutes, waits for the noise to drop below 39db for at least one minute, then sends an alert.
