LED lights still glowing when off

A while back I noticed some of the led lights not completely dark, it might be half dark sometimes then other times appear all on but super dim. Yes, I did google it and there is an explanation but I don’t recall the details and have already decided on an easy for me solution.

Solution:
I will use the existing timer controller and have it turn on/off a 2 pole relay to disconnect the hot and neutral circuit completely shutting lights off.

Will be making sure relay is sized for the load.

Update: Finished build, altered do to parts available.
