Since the LEDs have an input and output side, why not chain them together instead of having to make a T connection onto a main cable? This would put all the connections on the inside and not have any external connections that have to be protected from the elements. All that would need to be done is to add a second channel to the big screw.

I had a few reasons, although looking back, I think it wouldn't be such a bad idea either.

My main worry was that the first and the last icicle wires would have to carry the weight of the entire chain. I did end up attaching the hooks on top, so I guess that solves the weight problem, but I haven't thought about the hooks yet when I was planning it.

My other reason was that I could use a thicker main cable that can handle the combined current and only small cables for individual icicles. It's also a bit easier to add additional icicles afterwards (one T splice with 3 wires) than if they were in a chain (two splices with 4 wires).

But as I've said, I think if you're using only a few icicles as I did, chaining them would work just as well.
