The smallest wire on a boat should be 16 awg.
The panel lighting is powered by the red and yellow wires on the Blue Seas panels. The yellow is ground. Run the red wire, which is 16 awg, to a switch like a Blue Seas toggle (4150) and back to the positive bus on the panel. The run should only be a few inches if the switch is beside or above the panel and doesn't require a fuse in my opinion. As shipped the panel lighting on Blue Seas panels is not fused.
