I'm installing eyeball-type aimable incandescent lights in the rib above the baggage area. These lights are dimmable from a panel-mounted rheostat. I've got them aimed over the pilot's and copilot's inboard shoulder, but they can be swiveled as required (cargo, etc).
In these photos, I'm fitting and installing the mounting plate, match-drilling the screw holes, and running the wires through the crash bar and down the flap motor tunnel. In image 3 you can see the positive/negative wires encased in clear plastic tube to protect it.
