runway lights view distance lua settings

I've been experimenting with lua settings for view distance in the hope that I can increase the range that you can see runway lights. The only thing I've found that affects runway light view distance is the view distance setting in options. There's a noticeable difference on the runway lights between low and extreme but even extreme is not very realistic.

I've tried editing settings that made sense in Config\graphics.lua and Config\terrain\Extreme.lua but it doesn't seem to have any affect on the runway light view distance.

Does anyone have any ideas or is this hopeless?
