Night texture not working

Hi all,
I have an afterburner animation in my project, and I'm having some trouble getting the night texture to work properly.
I have the texture tagged in FSDS v2 as a night texture like so ..

... in daylight in FS it looks like this....

at night it looks like this...
can anyone tell me what I am doing wrong...
thanks in advance
