Anyone else want to weigh in on the proper way to wire these lights?
There are a few "proper" ways to do this and either a direct run or parallel run is okay, series would be a non-preferred method as would soldering the connections without crimping them also. Direct runs for each light are over kill and even high end builders don't do this. It takes up capacity in chases and can de-rate the current carrying capability of the bundled wires in the conduit or chases.
Crimp three ways terminals can be used but are horribly un-reliable in my experience. As a result I have not used one in perhaps 12-15 years. I see plenty of them and they are often a corroded or loose point of resistance.
Step down butts with two wires in one end and one wire out the other are also often used but I personally dislike this method as your wire diameter is rarely if ever the "right" size for the crimp terminal. I also use adhesive lined heat shrink crimp connectors so why waste the money if you can't get a 100% water tight seal. Two wires in one end will not seal with heat shrink.
Terminal blocks allow a lot of variability and are easier trouble shooting. Coated with terminal grease they can last for as long as the heat shrink connector.
I will generally run a main feed for something like the bow cabin lights including v-berth and head. I then pull off each individual light, with it's own wire, from the centrally located terminal strip. This usually keeps the individual runs for each light, from the t-strip, to less than 10 - 12 feet and saves a ton of wire when compared to running all the way back to the panel.
I always prefer the t-strips to be easily accessible and not buried or hidden. Therefore I do not use them at the individual light fixture to feed/daisy chain over to the next one as they would often be buried behind a head liner.
There are many ways to do this. Most reputable pros I know choose terminal strips. If you want to wire you boat safely you may want to join the ABYC, they offer individual memberships at a reasonable cost, and get the standards.
