Thank you very much
These things are shelving supports I got at Hope Depot:

The picture is not exactly what I have used, but very close. The round parts were cut out and a holes made inside to house LEDs. I am going to use flat head LEDs this time for my Hasbro build. But really you can just take an acrylic rod with the diameter big enough to make a hole to put an LED inside. Then, drill holes where lights should be in the hull of Falcon and make sure the fit is tight if you put a bit of acrylic rod in. It will serve as an LED housing. Mask inside of the rods and paint the inside of the hull with light reflective paint (black, silver etc.). Insert the LEDs into the pieces of the rod, then apply hot glue to secure it from the inside of the ship. For the smaller diameter lights I was warming up fibers until they start to melt and become sort of blob-ish, then use that part to embed it into the hull of the Falcon. Same idea as for fiber optic light installation for gun sights. Hope this helps!
