I had to brute force some of them to the length of the lights and how the wire connects them to the panel where you can put the lights is the key for most of the puzzles which can be confusing cause some panels that have lights that have wires that go to later puzzles there was one puzzle where I didn't even see a clue or a hint to so I brute forced that one but when my youtube video gets done processing hopefully it'll be helpful in your play through.
