Here is my sign I built for the roof of my house. I know the N is backwards, that has been fixed. Luckily it was the last letter instead of a middle letter. This is before I finished, but can see the words. Frames are built, the N is turned around the correct way, and the unused light has been blacked out since.
Frame is built from PVC painted black, rope light is zip tied to wire mesh. Each letter is 2 feet high.
Just some random sequence to see them play.
