The Brightdoor is a concept door for those people who cannot read simple sign language and would take a great risk to their lives or limbs if they persist on entering. Clearly conceived by someone who's interested in designing sci-fi movie sets, the Brightdoor contains one massive light that changes from a welcoming green when it's open to a stop-right-there-cowboy red upon locking. Maybe its for those who are so drunk that they cant tell the difference between an exit door and a reactor room.

Even though it's occasionally colored green, lighting up an entire door just to tell people it's locked probably isn't the most eco-friendly indicator considering the power it would need.
