What's the best way to do this. These are 12V LED lights I'm using for floundering and they need to be attached very solid because the sound has a lot of chop some nights and they will take a pounding over time
if you have bullet terminals you might get away with making your own plug use the female ends after you crimp the wire.
it won't be pretty but it should work for in the boat and framed nice you even see it, just mark the positive. and fuse after swich.
good luck I hope that helps in some small way.
