Ordinary emergency signs will work and make sense during an annoying fire drill, but what what if there’s, you know, an actual fire happening? You would have to crawl on your hands and feet in a smoke filled hallway and will be pretty hard to see the signs above the doors.

That’s why the Halo Light makes a lot more sense than the current emergency signs. Instead of glowing above doors, the Halo Light beams down circles through the smoke and onto the floor, allowing people to easily find their way out. This light surely beats the signs we see today and probably sooner or later we might them being installed in buildings.
