LED Device for Alarm Status for Doors

It would be awesome if I could purchase an accessory that I could stick to the door with an LED alarm status. I simple device the size of a sensor OR an LED built into the Door Sensor that would show red or green, or just red when armed.

Our back door is further away from the alarm keypad, and we don’t always realize the the alarm is beeping until we come back inside after letting the dogs out in the morning. A simple LED on the door or door alarm sensor would be a quick check to remind us to disarm. Thanks!

Agree!
I had a couple of false alarms when I hastily exited my home with the alarm being armed.
I solved the problem by hanging a cardboard on the doorknob showing the alarm is on. Would be nice to have a high tech version of this that would show the status in real time. Having a LED indicator on the door/window sensor is a great idea also, but for existing installations, just a device that I could stick on the door/window showing the status would be great.
