When you need light, you can pick up the Halo on the bedside wall, hold it and walk safely through the darkness. You can also wear it on your wrist to free your hands. When you are back to your bed, hang the Halo back to its holder, and the light is off automatically. Halo nightlight provides a more efficient and comfortable solution to walking in a dark room. You will no longer suffer the pain and inconvenience of falling over or hitting yourself with furniture.
