Led indicator light BA9S 12Volt with 10 leds is included in most Piaggio and Vespa scooters.
This led light is a replacement for the original indicator light. The big advantage of led is that it lasts so long that in most cases you don't have to worry about your lighting for the rest of your life.
It is also advisable to order resistors with this indicator light. If the indicator light is mounted without resistors it can work well, but it can happen that the indicator light flashes too quickly. A resistor solves this.
