They do not come strung together. Like the nav lights came as a red 4" led light and the green as a 4" led light. The kit comes with 3 toggle switches. A 10 amp fuse that you can wire in. I only soldered the connections just to be on the safe side. But yes a mechanical connection would work as well. Just heat shrink over the connections. I think since my yak will probably never see salt water that the connections should be ok. The kit comes with a wiring schematic. And once you break it down what goes where, it's a piece of cake to wire up.
