What it is

Summary

AI-generated from vendor-published content · October 1, 2026

The Krown DoorKnocker 125 is a knocker that hangs over the top of a door and flashes a bright LED when someone knocks, so you can see that a visitor is there even if you can't hear the knock. It works on its own, with no tools or wiring, and the hanging bracket comes in the box. It runs on a 9V battery, which you'll need to buy separately, and it has an on/off switch and a low-battery indicator. This is a good fit for someone who is deaf or hard of hearing and wants a simple visual cue at the door. Because it flashes only when the door is knocked on, it won't alert you to a doorbell.
