I have QW 757 running with REX 2004. The nav lights are really big! I ran the lighting mod on REX but still have very large nav lights.

I see what you mean, just fired mine up. I believe these are generated by a bitmap (guys and gals please correct me if I am wrong) so there is little you can do to mod them without editing the bitmap directly. I believe the REX mod only edits the environment lighting and not the aircraft's.

It's probably the Halo.bmp in your main Texture file that's been replaced.Back it up and try these from the Avsim library if you like: airport_lighting_v2.zip.Not sure if REX also edits the Display field in your FS9.cfg file, but that will effect Surface & VASI lights as well.
