I also have the input to the relay working correctly. I can switch on and off the relay but the lights never respond accordingly. I'm also tried swapping the two wires in the two NO/Common gates. Is there something I'm missing?

The relay is either working or it is not working. It is a simple matter to connect a meter to the contacts to measure continuity or make a continuity tester with an led and a resistor so the relay turns the led. OnAre the relay CONTACTS closing or not ? That means you need to test the contacts. We don't really care about the leds on the relay board. We are interested in the contacts.
Maybe that's what's wrong in this post.
