Ever found yourself in a situation where you were literally caught with your pants down simply because you forgot to lock the bathroom door while trying to lay a log? Well, Emtek clearly believes that prevention is better than cure, hence coming up with their illuminated door handles that will signal others whenever the room is occupied. A single AA battery is required to power the exterior handle, where when locked from within, it will light up fully, otherwise it comes across a color-spotted handle. Whatever happened to those simple color coded twisting lock mechanisms that we see in public toilets?
