Review on Nilight - 50056L: Waterproof 12 Way Blade Fuse Block with LED Indicator & Negative Bus for 12V Automotive Cars, Boats, and RVs by Jeff Bundrick

We bought a few of these - my son was repairing a vintage 1988 work truck, with the usual obscure mods/hacks to the electrics system along the way of years. He decided (perhaps correctly) that it would be easier to rewire the chain one at a time, so we grabbed a few of these and started pushing things around. They're compact but seem solid, and we like the red light that indicates a healthy circuit, which is really handy when debugging (and will be nice when you're done so you can easily see if a fuse is blown is). I like it so much I'll probably get another one when I convert my boat.
