Signal Smoke Detector Concept

The Signal smoke detector concept by Matthew Jobson might look ordinary, but it does boast something standard smoke detectors don’t. Whenever the Signal runs out of batteries, the lid will open to display the housing, giving a visual alert to folks living under its roof that it is time for a battery replacement. In addition, it will come with glow-in-the-dark arrows to make it easier for kids to find their way out of the room in the right direction should the smoke detector go off.
