This is eye-candy at best; it's not like it's actually needed for any reason other than that.
Seems funny to me that a historical apparatus used on all US carrier decks is described as "eye-candy." Maybe the tiny useless propeller for the electric generator modeled on the 163, or the useless spinning jet turbines of the 262, or the useless spinning turbos of the P-38 are equally "eye-candy" but they don't even serve a conjectural utilitarian purpose other than that. At least historical lights on the con would provide some help to judge carrier disposition on final, or when taking off under attack and you are looking over your shoulder at incoming cons. And as a matter of historical record, planes did not takeoff or land when flight operations were secured, such as when the carrier was turning. But if you like to game the game, I can see why a historical light system wouldn't float your boat. C'est la Vie.
I guess when I'm around for 14,000 posts I'll get to say "you've got to be kidding" when someone suggests more immersive effects that would provide some measure of additional help in coping with the game.
By the way, regarding other comments above, Zeno's is showing a free video on FM-1 and TBF cat shots from a carrier in WWII.
Best regards.
