I'm running Prepar3D v4. How can we make the beacon lights from the tower at night look better? I've tried upping my graphics settings as well as tried to use Prepar3D Tweak Assistant, but no dice.

I would LOVE to see a solution!

It depends, the tower lights are embedded as objects or effects.

If it is a object you need ADE, create your own improved object, edit the airport and compile an updated BGL.

If it is an effects, you need ADE to find the effect name  to edit it with improvements, which might require new textures.

Both cases you need to edit the scenary as developers do for each airport tower that you wish to improve.
