Brightdoor for the Clueless

How many times were you tempted to touch an object with a sign, “Do Not Touch” hanging right above it? The Brightdoor is meant to make sure everyone gets the message even if they don’t speak or understand the same language as you. The Brightdoor comes with one massive light which changes from green to red whenever it is locked, pretty much like how a traffic light works. I wonder how much more power this will take up in your home should you decide to install it.
