Fuses prevent things from burning out, which could turn your entire scooter into a smoking pile of plastic and metal—and hopefully also prevent expensive electrical components from being irreparably damaged.
Always use a fuse with the same specifications, and not, for example, a higher-rated one because it keeps blowing, after you have found and fixed the cause of the blown fuse.
The price is for 5, so if your fuse blows again, you already have spare fuses at home.
