Extreme Series Train Horn for Hart® 20v Battery
Every tailgate lot has one crew everybody hears before they see. The Extreme Series is how you become that crew. It is the most powerful model in our Hart® lineup — a 150 dB battery-powered train horn that snaps onto the same Hart® 20V pack you already keep charged, with no cords, no air tank, and nothing to install.
What You Get
- 150 dB of deep train-horn sound — a tone that rolls across a stadium parking lot, not a tinny party air horn.
- Four tuned metal trumpets finished in a tough powder coat.
- Wireless remote with 160 ft of range — or step up to the long-range version and trigger it from as far as 2,000 ft.
- Hart® 20V compatibility — runs on original and aftermarket Hart® 20V batteries — the same packs that run your drill and impact driver — with long-lasting sound from a single charge.
- Zero setup — click a battery in and it is ready to sound.
- Same-day ship-out on orders placed before 12 PM PST.
From the Parking Lot to the Campsite
Picture Saturday: the grill is going, cousins are tossing a football between trucks, and kickoff is an hour out. One press of the remote and your whole row knows where the party is. Because the horn is completely cordless, it moves with you — tailgate, backyard watch party, car meet, campsite, or out on the water.
It earns its keep beyond celebrations, too. A 150 dB blast makes a serious outdoor attention signal when you need to reach someone at a distance. Use it responsibly: wear hearing protection, keep it pointed away from people and pets, never fire it indoors, and let the remote do the work from far off.
