Trailer Connection Horn Prank
About This Item
This is a novelty gag device designed to deliver loud, hilarious surprises by connecting directly to a vehicle’s trailer hookup. Compact and easy to install, it works with both 7-way and 4-flat trailer wiring, making it compatible with most trucks and cars equipped for towing. Once hidden behind the bumper, the horn activates every time the driver presses the brakes, blasting a powerful 110 dB sound at 510Hz that’s impossible to ignore. Made from durable plastic and powered by the vehicle’s existing 12V wiring, it’s reusable for multiple pranks—whether you’re targeting a coworker, a new driver, or even family members. Measuring 16.5 x 4 x 3 inches and weighing just over 12 ounces, it’s lightweight yet effective, offering endless entertainment for those who love practical jokes.
