Perfect for

For those who have broken or clouded the front left turn signal lens after a fall, a parking bump, or simply due to the age of the vehicle, and want to get back in compliance for inspection without replacing the entire light assembly. It is also the choice of those who keep their Beverly or Liberty in good condition and prefer the original Piaggio part over a third-party equivalent, for fit and durability over time.

Frequently asked questions

Is code 639122 the right or left side?
It is the left side, front. The right side corresponds to a different Piaggio code.

What is the difference with code 584478?
None in terms of installation: 639122 replaces 584478. If you find 584478 in your catalog or on the old part, this is the correct spare part to order today.

Does the package include the bulb?
No. Only the transparent lens is provided: bulb, bulb holder, and turn signal body remain those already fitted to the vehicle.

Will the turn signal blink white?
No. The lens is colorless by construction: the amber color required by traffic laws is provided by the orange bulb installed inside, as in the standard configuration.

Is it suitable for my American BV?
Yes. The Piaggio catalog lists the same code for both EMEA (Beverly) and NAFTA (BV 250, BV 300, BV 500) versions, as indicated in the compatibility table.

How can I be sure it's the right part?
Compare the number printed on the old lens (639122 or 584478) and check the model and year in the table above. If you have any doubts, write us your chassis number: we will check it on the official catalog.
