Red light is the most difficult color for people to see in low light. Green is the easiest.
That's why night vision goggles are green. They could make them any color. That's probably also why the lights on that navy ship were red. If it doesn't mess up your night vision, it's probably just because it doesn't look as bright.
However, since red is the most difficult color to see, it doesn't make any sense why you would want a red light to see with. It's just a marketing tool.
Welcome Steve. I stopped in the shop a few weeks ago to say hi, but you weren't around. Anyway, hi.
