Thanks. I'll make sure to put it between the switch and the battery than. The rest of the diagram looks okay though?

The switch I have is rated to 30amps. I have an inline mini-blade fuse holder rated to 30 amps. I figured I'd use a 5 or 10 amp fuse since the lights are only 0.85 amp each. I already have 18ga wire, so I guess I'd just use that since they can handle roughly 16amps. Plus the wires from the lights look to be about 20ga, so that should work out fine, I would think. What do you think?
