Is there a problem with the strobe lights not functioning (does the J41 even have strobes or just the CONSPIC lights?), or the white nav light shining, or the beacon flashing? Also, I dont see the actual nav lights themselves, all I see are the glow cast by the lights, but the actual light source is missing.-Phillip

Full name please, Phillip.Have you modified FSX textures with an add-on such as REX? This is the common reason why lighting effects change.

I currently have GEX, UTX, and FEX installed, and I just recently started using Shockwave 3D Lights--however the external lights weren't working before the use of Shockwave. I did notice that the taxi/ landing lights weren't working because I had replaced spotlight.bmp, but I restored that and got those working. You mentioned that REX messes with light textures, does FEX do that as well? I'm not so sure it does.Thanks, Phillip
