Cheers! I've wanted to put the green and red navigation lights in Project Airbus a321, but i've already tried to add the lines, but since the wing moves, the lights stay at the same place, they are static. In project airbus a320 that doesn't happen. So, I tried to find a solution and what I did was, replace the fx_shockwave_navred by the corresponding red navigation light file in project airbus a321. It worked like a charm, however not like I was expecting. Im going to try to explain myself:
I wanted the lights to look like this:

The lights in the image above, shine and can be seen from a great distance. Eg: When the plane is in the air (at night) I can see the red and green lights.(In PA A320).
But they don't shine in (PA A321, because I replaced the file and dind't add the line in cfg like I've done in PA320, but due to wingflex, lights tend to stay at the same place, and so, even when I zoom out I can't even see the lights...)
Hope someone will come with a solution!
