We'll use this post as a central spot to gather the config files that will be shared with the community. When you've completed creating the spotlights for your add-on aircraft please upload/add them to this post.
Included are my 737NGX_Colors.ini file that tweaked the colouring of the PMDG B738 and the FSLSpotLights.ini file for lighting. Both are for P3D4.
REMEMBER TO BACKUP YOUR FILE BEFORE REPLACING THEM~!!
The 737NGX_Colors.ini file goes to c:\Lockheed Martin\Prepar3D v4\PMDG\PMDG 737 NGX\
The FSLSpotLights.ini file goes to c:\Lockheed Martin\Prepar3D v4\SimObjects\Airplanes\PMDG 737-800NGX WL\
