If your horn only blows intermittently or requires you to mash the button with intense thumb pressure, oxidized copper contact plates inside the old housing are the culprit. Installation Tip: To replace the switch without scratching your scooter's painted handlebar covers, avoid metal screwdrivers. Use a nylon or plastic automotive trim tool to gently pry under the edge of the old switch housing until it pops out of its retention tabs. Pro Tip: This specific switch housing shape is highly standardized across the Piaggio family of scooters. If you look at the right-hand side of your handlebars, you will notice this horn switch shares the exact same footprint as your Electric Seat Release (saddle pop) button and your Starter button—meaning it's smart to keep a spare in your toolbox.
