Fire Extinguisher Signs

There are many different types and sizes of fire extinguisher signs and fire safety signs. But, despite appearances in pictures, all are not created equal. Rigid plastic fire extinguisher signs come in varying thicknesses and varying quality of ink. What is the point of a sign that fades over time?

The problem with the standard rigid plastic safety sign is that they are only visible when the lights are on or daylight is present. In emergencies such as a fire or power cut, this can cause panic and injuries and would you really want to be sued by an employee or visitor for the sake of a quality exit sign?
