Have you ever had trouble finding your way to your door in nighttime? If your light is broken, you are going to have to deal with that. Putting your key into the keyhole properly can be a bit of a challenge when you can’t see anything. The Concave Lock could help with that. It’s a concept design by Poh Liang-Hock that adds a glowing ring around the keyhole so you can find it easily in the dark. Its concave shape is helpful too. The idea has a lot of potential.
