I've used these Galactic Mammut gel connector blocks
for where I've needed to join wires - especially where the join will get wet. One of the real advantages of them is if one of your nav lights fails, you can re-make the join with a new light without any special tools or a heat gun (like if you use heat shrink joins).
They are also really good for connecting bilge pumps as they can sit in water in the bilge without any problems, and when the pump fails are easy to re-make.
They are also relatively cheap
