Horn Button for Vespa LX, GTS 250/300

Horn Button Switch for Vespa LX and GTS Models

This horn button switch is a drop-in replacement for the original part on several Vespa models. It suits the Vespa LX, S, LXV, and GTS 250/300, along with compatible Piaggio scooters. Like many Vespa scooter parts sourced from the factory, it fits into the spot where the old unit was removed, so it is a practical choice for home mechanics.

Build and Styling

The housing is molded from UV-resistant ABS plastic, a material that holds up to everyday riding. It uses a rocker design with a raised horn symbol so the function is easy to recognize at a glance. The casing is meant to resist moisture and knocks, which helps it keep working over the long term.

Setup and Compatibility

The unit slides into the original handlebar housing and needs no special tools or modifications. Its connector is made to plug straight into the existing wiring harness, so hookup is simple. It is a good option if your current horn button has failed and you want a quick swap.
