Those who are hard-of-hearing or deaf could make use of the 'Light Bell' visual doorbell as a means of ensuring that they never miss when someone comes to their door. The 'Light Bell' consists of a specialized lightbulb that works by being installed into a light fixture or lamp of your choosing. The lightbulb will then work to provide visual feedback (five on and off cycles) when the doorbell is rung to let the inhabitant know that a guest is at the door or that they have a delivery.
The 'Light Bell' visual doorbell is the design work of Ian Bok and takes a simple yet genius approach to creating a system for those who are deaf or hard-of-hearing to live a better lifestyle.
