Perfect for

This is the spare part for anyone restoring or putting a 1980s Vespa PK S back on the road and finds the rear left turn signal broken, faded, or with a cracked lens: a stationary fall, a parking bump, or simply forty years of sun exposure. Installing the original Piaggio part means getting the same shape, the same amber color, and the same mounting points as the original, without having to adapt holes or wiring. Also useful for workshops preparing a PK for inspection: an intact and functioning turn signal is one of the required checks.

Frequently asked questions

Which Vespas does the Piaggio 216784 turn signal fit?
The 216784 rear left turn signal fits Vespa PK models of the S series: PK 50 S and S Lusso (frame V5X2T), PK 50 SS (V5S1T), PK 50 S Automatica (VAS1T), PK 80 S (V8X5T), PK 125 S, and PK 125 S Automatica. The table above lists models and years.

Is this the left or right turn signal? What is the code for the other side?
Code 216784 is the rear left turn signal, which is the one on the left when looking at the Vespa from behind. The symmetrical part for the rear right side is Piaggio code 216785. The front turn signals of the PK S have different codes: if you need a front turn signal, please contact us before ordering.

Is the bulb included in the package?
No, the 216784 indicator is supplied without a bulb. You can reuse the bulb from the turn signal you are replacing, if it is still working, or install a new one of the same type. The bulb holder is already integrated into the body, and the electrical connection is made via the terminal on the back.

What exactly does the spare part include?
It is a complete turn signal: black plastic body with bulb holder, amber lens with two screws already fitted, and two threaded studs with nuts for attachment to the bodywork. It is not just a replacement lens: the entire indicator is replaced, making it the right choice when the body is also broken or the fixings are damaged.

Is this an original Piaggio spare part or an equivalent?
It is the original Piaggio spare part with code 216784, new and never mounted, the same one specified for Vespa PK S models at the time of manufacture. It is not an aftermarket turn signal with its own code: the shape, the amber color of the lens, and the position of the fixings correspond to the factory-fitted part. It is shipped from Italy with an invoice.

How can I be sure this is the right turn signal for my PK?
Check your Vespa's frame designation, as indicated in your logbook: if it starts with V5X2T, V5S1T, VAS1T, or V8X5T, or if it is a PK 125 S from 1982-1984, it falls within the compatibility table. If it is an XL, XL2, FL, Rush, N, or HP model, or if the designation is not listed, send us the complete frame number, and we will verify it before purchase.
