Right side Red

Sailors use red to mark the starboard side of the boat and guide into port with the red lights on that side.

"red to the right" is easy to remember and makes it simple when deciding how to mark a set of cables or other connectors. Here is a piece of equipment with two sides, that's likely going to be taken apart several times.


I've added a small piece of red marking tape to the right side, so whenever I pull the pieces apart in a hurry, I don't need to worry about remembering which side is which.
