Toilet Guide / public facility

We design the toilet guide by virtue of red light and controllingits angle.
When there is someone inside,the light will be on automatically and thus form chatoyancy in front of the door to clearly tell people outside to find an empty toilet as soon as possible; meanwhile, it can save time to make a judgment and help
disperse the crowd.
What’s more, distance between the projected light in front of the door and the door is in close proximity to the maximum vertical displacement when the door is opened, avoiding the inconvenience and embarrassment which is incurred by the outward door’s collision to the waiting people.
