Best Navigation Lighting.

"Steiner" binoculars used the same effect to "enhance" the night vision of some of their models about 15 years ago. But it is just a "effect", as you said, and not really improving it. My old "Zeiss" have by far better light amplification at the same lens diameter.

For lighting the wheelhouse / nav area, yes. But the original question was about running lights!
There we have to install and operate just what we get off the shelve, we cannot dim them.

edit:
I read the article you linked to. Interesting reading and completely in line with my experience over the decades on the bridge.
The adaption time for example: it is a rule on my vessels, that the watch has to appear on scene 30 minutes prior to change of shift, and the person replaced has to stay for another 15 minutes before leaving the bridge. Coincidentially that (45 minutes) is exactly the time for a complete adaption to night vision.
Also I found again a confirmation of my dictate NOT to position screens like Radar in direct sightline of the helmsman but to keep a 60° sector ahead absolutely free of any illuminated or moving object. Installing plotter and Radar screens at a angle besides the helm allows for perfect detection by turning the head only a few degrees. (due to peripheral zones effect)
sorry for the aside

Go to the US Govt bookstore and buy a copy of Rules of the Road.

All the info is in there.

You should keep it on your boat and memorize the book verbatum.
