Our KLAS scenery obviously has night textures on the tower, including red warning lights, as can clearly seen by the screenshot below.
I think the picture you posted is quite unrealistic, because it's too bright, it looks more like a picture taken with a digital camera (that results in increased night lighting, because of the automatic exposure) compated to what can be usually seen with the naked eye, and of course the texturing is almost entirely flat.
We might try to make the red warning lights a little but more visible, but it's incorrect to say "you do not have any night lights in the control tower, or red warning signs on the tower"
