Taxiway Guidance Signs

An internally illuminated elevated sign carrying mandatory instruction (white on red), information (black on yellow) and location legends along the taxiway. Internal reflective lighting fills the face evenly, leaving no shadow to swallow a character seen at an angle; frangible poles run through the extruded aluminum box, so it stands the wind yet breaks away instead of damaging an aircraft. The front door opens without tools and lifts off, and the driver is modular, so a repair is a part swap, not a sign removal.
