Alarm on stick up

Convenient for my family would be a small battery powered LED light that could be stuck on a door or door frame where the light would be ON when the alarm is active. Sometimes some of us forget, and set off the alarm letting the dog out in the middle of the night, or whatever. It might also be good for my doors that have glass in them for someone to see, light the alarm light in a car. It could convince them that the sign in the yard is real. (If they don't see all the cameras and spotlights ;-)
