About Round Type 35

This device helps users recognizing if the light inside a room is on from outside. The indicator lens can be easily attached to the door by pushing it into the hole (prior drilling needed). The thin ring on both ends is designed with a wider surface to hide the mark of the drilled hole on the door.
The design is thin and well-trimmed, so it does not muddle the design of the door. We provide 7 different colors to complement any doors color.
