Cargo and Tail Inspection Lights/Switches

I'd been debating on what lights to use for the cargo bay area and also for the tail section behind the rear cargo bay wall. I finally decided on rope led's. What tipped the scale for me was that I could cut them to length and they spread the light out over a broader area.

The next decision was where to put them exactly? As with all modifications, one decision leads to other problems. For example, I intend to cover the interior of the cargo bay with the Oratex fabric. Standard practice has one do the top of the cargo bay first before moving on to the sides. However, my decision to use the rope led's means that if I cover the top of the cargo bay it takes away the mounting position for the led's. Moreover, it also takes away (covers up) structure that could be used to mount items or use to secure cargo. So, I've decided to not cover the inside top of the cargo bay. It won't look as finished, but I can mount the led's in the most advantageous location and gain some extra tie down structure.

As for the tail inspection light, that was an easy determination. A cross member on the top of the fuselage. Considering the Silver Oratex has a black backing, that tail area will literally be a black hole. So, the addition of a light back there for inspection purposes will be greatly appreciated when it comes time. It casts a great amount of light though the whole rear of the plane. Makes inspecting/repairing anything back there much better.

Finally, I had to decide where to put the switches to control these lights. Actually, there are not a lot of places to mount them but I found the most convenient spot was in the cargo door well. I cut and Hysol'd a fabric/switch plate, drilled the holes and mounted the switches. My plan at this point is to have these always hot so I can just open the cargo bay and switch them on without having to do anything else, they're LED's and don't draw much. Besides, it will be really obvious if I leave them on.
