It depends on what you mean by "size?"
If you're talking about current rating it depends on the wire gauge in the circuit, and each 55W lamp will take about 4-5 amps at 12 volts. Fuse it for the smallest wire in the circuit.
If you're talking about physical size and glass fuses, the only way to know is to measure the fuse holder. For example, a 1" fuse would be an 8AG; a 1.25" fuse would be a 3AG or 4AG. Those are the most commonly seen sizes.

amps = watts / volts
so
55w / 12v = 4.59 amps
or 2 Hellas need a 10amp fuse, or 12-15amp would be "safe"
Here's a dang good write up if you want to read thru:
