Tis the season for odd projects.

Work was getting ready to excess a bunch of electric parts they don't use anymore. Including some small bulbs, leds, capacitor, resisters, switches, etc. Some pretty cool stuff if your into that, I am but don't know enough about it yet. I jumped in to give the parts a second chance.

Instead of the usual small flashlight duct taped to the body. I thought I would hook up some lights for the RCs so I could tell if they are coming or going. Get's dark a little after 4pm now. Not a lot of daylight after work.

I was going to take the 8ight out test it out in the snow we got today (the LS10 did great). I thought I better cover up the couple of bulds connections real quick. Grabbed the hot glue gun and covering them up. All was good until I plugged everything in before the last ones hot glue had time to fully dried and poof. I thought I freid something down the line. Everything turned out to stll work (ESC, BEC, Receiver, servo) except my lights.

Finally to my question. If I install an inline fuse in the lights connection wire right before it connects into the power source. Would it have blow before doing any damage to the electric parts or battery when I shorted it out?

If yes it would protect them. Then what size fuse would be appropriate? Is there a formula that should be used to determine what size amp fuse? Should it be installed on the positive or negative side? Does it matter?
