Here is a video that might help the developers make a better lighting system for our aircraft or for project metal Because currently the lighting systems are very hard to see at night
To add on, developers know what they need to add, and probably how they are going to do it. It just takes time to get project metal done, as well as then the actual coding of the lights them selves.
But there are a few lights that are missing such as logo lights and taxi lights
See attached requests below.
The developers are well aware of what lights are for what purpose. Once the new graphics engine comes into play it may open the door for other features to take light. (no pun intended) (ok maybe)
