I have a large Hunter fan with wide blades that I installed a number of years ago. It had the lights as well. Installation was straightforward and all the wires were color matched to the appropriate plug module. Easy as pie or so I thought.
I got it all wired up and closed up then tested it. Everything worked except the lights. Took it apart and everything matched the instruction manual. Still no lights. After several rounds of playing with different routing I came up empty. The lights are just decorative now. I never figured it out. The fan works well.
