The best way to signal if you don't want to be bothered. Use it outside your room to let people know if you're feeling antisocial OR if you're just busy with work.

Mounts on your wall or rests on your desk

The stop light is designed so it can sit on your desk, or mount on the wall. Use it in your home office, or outside your room. You can mount it to the wall using command strips

How does it work?

The puck light sits in a track inside the social signal. There's a slider on the side so you can change the color based on how busy you are. Magnets hold the light in place.
