I love THESE, can't get any closer to the battery than that.
You'll want to attach it to the battery with the correct fuse block for your inverter. I had this one on my Leaf with a 150 amp fuse: https://www.amazon.com/Blue-Sea-Systems-5191-Terminal/dp/B0019ZBTV4
I used

I cut the loop of wire real short on one side. Crimp on a connector to attach to the battery. Do that with 1 inch from battery to fuse. The other end goes to the fuse box or bus bar.
These can attach directly to a battery stud

Search for "anl fuse" for another heavy duty style.
Here is the fuse mount and here is the fuse I use for my battery. Goes right on the + terminal.
Something like this.
Also available on Amazon.
Fuse itself sold separately.
Nice solution to get the protection right on the battery terminal.

Added some monitors and shunts to the previous setup. What do you think?

For your case, you want to stick the fuse right on top of the battery so you can then use a thin wire that is appropriate for your light. You choose a wire gauge appropriate for the light's current draw, and then choose a fuse able to protect it.
Most boats have lots of circuits, so they use very heavy cables that can handle the current supplied by battery running flat out (which can be hundreds of amps), and these heavy gauge cables run to a fuse block that then has fuses for each circuit.
