Soartex Fanverwhat texturepack is that your using on those pics??
This was going to be my suggestion too. That wiring looks exactly like the real wiring you see suspended from telephone/power poles.Immersive Engineering has a very nice-looking item, the "Wooden Post". If you hit the side of the Post up near the top of it with an Engineer's Hammer, it pops out an "arm", and you can then attach a light source to the bottom of the arm. It looks very nice IMO. Immersive Engineering is a very nice looking mod, especially when you connect the poles together with wiring making it all look quite realistic compared to real life power poles and light poles. If one Wooden Post is too short, then just use 2 of them, one atop the other.
Finally remembered. It was something I did in minecraft a version or so back. A inverted light with a daylight sensor on top of it. It has so much more potential now. as Carpenter fence can be used. Back then i was only using vanilla fences.inverted light sensor on top of of a redstone lamp. decorate as desired?
Edit:
Sorry. guess that is a 1.8 thing
