Hello, Post on the LED replacement is terrific. Helped me replace all lights except for 2 in the Head because I can't open them. I turn but nothing happens. How do you open them? I haven't replaced the rope lighting. You wrote: Rope Lights- 15 feet needed - need 3 dc to ribbon cable adaptors Question: Are the 3 Dc to Ribbon cable adapters in the list or is that extra?
