What this product does ?
An exit sign is a device in a public facility (such as a building, aircraft or boat) denoting the location of the closest emergency exit in case of fire or other emergency. Most relevant codes (fire, building, health or safety) require exit signs to be permanently lit. Exit signs are designed to be absolutely unmistakable and understandable to anyone. In the past this generally meant exit signs that show the word "EXIT" or the equivalent in the local language, but increasingly exit signs around the world are in pictogram form, with or without supplementary text.
