What I learned the hard way about the linkable ones, at least the ones from Costco, is that just because they are linkable does not mean they work in unison.
What I had envisioned was that I pull the chain on one light and the entire string would come on, that isn't the case. What I ended up doing is turning them all on and just disconnecting/reconnecting at the power outlet of my storage unit.
