Hey man, I could be wrong but I'm pretty sure that the Red light is to indicate Power and Green is to indicate Ground. If you have a fuse that lights up green it means its touching ground somewhere Which would indicate a fault in that circuit. All the fuse's in cars fuse panel are to protect 12volts power supply's not negatives. Not trying to police your content just sharing what I've learned.
Cool. You can also take pictures on your phone of the fuse diagrams in your manual for easy access. Then keep this tool and some quality fuses (I use littlefuse) in your vehicle. For ten bucks, it's a no brainer.
does the key have to be on the "on" position in order to test if the fuse is good? also how do you get get a power point inside the the car if the cable is not long enough or can you just ground the black to the body like a normal test light?
I use a pair of cheap Jumper cables to extend the test light inside the vehicle (make sure to tape up the ends between the jumper cables and rest light leads.) also whatever circuit you are testing should be powered up to test it, so usually yes the key should be on.

Great video, hope to see the follow up videos soon as you have time.
Great video, thanks for this!
Thanks so much that was very helpful!!
Thank you for this. This helped me a lot

i bought this same one last night.
What if need to test interior fuse box? Need to plug since the battery? On my PK is on the opposite side so probably will need longer cable
Can this work on the relays?

Whats it mean of the fuse is blinking green
Ok it says negative when green light is on so how is it good?
Thank you
Explain better about the green fuses
Can it be used to check for spark on ignition coil or spark plugs?
yes
You talk too much
