This 8-amp fuse protects the Vespa's electrical system from damage. This torpedo-style fuse fits perfectly into the original Piaggio fuse module, including the Vespa PX 80/125/200 and Sprint models with a battery.
A fuse with too low an amperage provides insufficient protection for the electrical system, while a fuse with too high an amperage creates too much resistance for the electrical components (lights, etc.).
