We offer a lens that is specifically designed to fit the square korry. You can choose from the standard text of a 737 part or customize the text to suit your needs. You can opt for either:
 
A clear acrylic lens, which makes the text look black and hard to read when it's off,
 
or a white acrylic lens, which makes the text easy to read even when it's off.
 
It's important to note that the color of the caption is dependent on the LED colour, not the lens colour.
