What? 4 minutes up and no "behind the green door" jokes??? Oh, wait...

The friend of every teenage boy.

Mother of a teenage boy, "Why is the bathroom door always red?"

Plus, sorta makes your house an instant target if you leave you door unlocked, doesn't it?

@max.goedjen:

No, not unless you have a crutch with a rambo knife attached to the other end waiting for some unsuspecting cable man... [gizmodo.com]

I saw this once... in a horror movie.
Or was it another type of movie?

I thought this was for christmas when I first looked at the picture and I thought about choking any neighbor who would actually put it on display.

I want this for my dorm next year

I don't care what it costs

Or how many rules it breaks

On another not if you have trouble sleeping just cover the side of the door that you are on with something

i like the brightdoor handle system... id like it on all the doors in the world, especially bathrooms and bedrooms,

but this seems to be overkill

@Synik103: Bastard...beat me to it, I guess that means we are the old ones

Actually, it would be very useful AND important in public buildings to mark emergency exit ways. Imagine you are being some place you don't know your way around, all hell breaks loose and you have to find a way out. Time spent rattling on closed doors could fry your arse. Instead you could be faster in the stairways where everybody is falling over everybody else...

You could add these onto an awesome set to help create a live action video game.

Why stop there? Why not have the entire house glow green when the front door is unlicked?
That way you could waste even more energy while advertising your vulnerability to the world.

Oops!
Obviously I meant to say "unlocked" instead of "unlicked" in my previous comment...

So if a Dutch hooker's door is glowing red, does that mean she's open for business or that she's with a client?

These could look really good in a club or something. Imagine a bathroom with stall doors like these!
