Fuses for LED Lights and Fans

I have a 12V DC fan drawing about .8A and then two small LED panels on the top plate but I thought I should protect the power supply by putting in some inline fuses.

Questions:

I don't have and can't find any data on the LEDs in terms of amperage. I'm enclosing a photo of them.

One fuse or two? (in other words tie the two together and then a single fuse between them and the power supply.)


What amperage?

I was thinking about this type - looks pretty painless:

those leds look like a 20ma set up you really don't need a fuse in line they should be a 12v led module and being a Diode they act like a fuse when they blow if they do blow they become open and power will not flow anymore. if you do put a fuse inline a 1amp will suffice. you will only be drawing approx .100 ma between the fan and leds if you are running them in series.
