Fuses prevent things from blowing, which could turn your entire scooter into a smoking pile of plastic and metal, and hopefully also cause irreparable damage to expensive electrical components.
Always use a fuse with the same specifications, and not, for example, a heavier one because it will blow every time you have found and repaired the cause of the blowout.
The price is per 5, so if your fuse blows again, you already have spare fuses at home.
