Which of the following is NOT a correct guideline for NEW externally illuminated EXIT signs?

The main idea being tested is how exit sign design targets legibility and clear direction during an emergency. For new externally illuminated exit signs, the standards emphasize readability and proportionality to ensure quick recognition. The directional indicator is meant to show the direction to the exit, but it does not have to be restricted to a single form like an arrow in every case. The requirement is that a clear directional cue be provided, and arrows are a common way to convey that direction, but the code does not mandate that it must be an arrow alone in all installations. The remaining guidelines align with established standards for visibility and proportionality. The letters must be large enough to be read easily, with a minimum height of 6 inches to ensure legibility at typical viewing distances. The directional cue should be legible from a distance of about 40 feet to guarantee quick recognition in an emergency. And when signs exceed the minimum size, the letter widths, strokes, and spacing must scale in proportion to the overall height so the sign remains balanced and readable rather than distorted.
