If you want to make a glow map for it, making the texture itself is quite simple. All you need to do is make the parts you want to glow white, and the rest black (much like a specular map really). To do this, all you really need to do is open up your diffuse map, then untick all layers unrelated to your 'glow'. Next, create a layer filled with black below all other layers, then desaturate the layers you're left with (the glow-related ones), then edit the brightness/contrast depending on how much glow you want.
I've just made a quick little example of what your finished glow map should sort of look like:
Also, did you do that fall-out glowing effect on the blue strips in photoshop afterwards? If so, you may want to remove that, as I'm not sure whether that's allowed because it won't look that way in-game(However, if it's just planes with alpha, then disregard that last comment. :P).
