This is a dandy! It has a light so it blinks when someone rings the doorbell. Great for hearing impaired. It also can be put to nightlight mode and make extra light for walking around in your dark house at night. It has 2 different bell sounds to choose from. Attatch the doorbell at whatever door you want it to be at, and plug in the receiver where ever you can see and hear it inside. Easy Peasy! Nice looking too, so I don't mind having it where it can be seen.
