FSX FSDS Transparency issue

Hi,
I am having issues when trying to make night lights for FSX, Basically I have the texture below in a BMP DXT5 format. It has a black Alpha Channel, the day texture is just a pure black texture in the same format again with a black alpha channel so that the light disappears during the day.

yet when exported in FSX it is invisible at night too... in FSDS Material properties I have added a material 'trans' as told to do so in this transparency tutorial:
http://farfyscenery.katuu.com/Tutorials/Objects that use transparent textures with FSDS 3.5.1.htm

I then placed the textures onto my object and exported it to an MDL which should show as all other models such as houses show fine...
what have i done wrong?
Thanks

In FSX (AFAIK) the night texture uses the day texture's alpha channel. So if it is all black the night texture will disappear too.

Thanks I think that has really helped... but if the day texture has the same alpha channel as the night wouldn't it have a visible area during the day? Thanks

If this is solid geometry and not an effect, I assume you could assign an XML custom animation that would make the part disappear during the day?

That's a good idea. I'm not sure how to do it but that approach should work. Thanks Tom!
