{"product_id":"hella-marine-tc16-dual-tone-boat-horn-kit-12v-113db","title":"Hella Marine TC16 Dual-Tone Boat Horn Kit, 12V 113dB","description":"\u003cp class=\"nvn-hero\"\u003eThe Hella Marine TC16 dual-tone horn kit gives your boat a deep, commanding voice that carries across a busy harbor. You get two trumpet horns, a 500 Hertz high tone and a 400 Hertz low tone, that sound together for a full 113-decibel blast. Black ABS housings and a galvanized bracket mean it shrugs off salt spray season after season.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eEvery boat needs a horn you can count on, and the Hella Marine TC16 kit gives you two of them. This set pairs a 500 Hertz high-tone trumpet with a 400 Hertz low-tone trumpet, and when they sound together you get a rich, layered blast that reads as urgent from a long way off. One horn on its own can sound thin. Two tones stacked on top of each other carry farther and cut through wind, engine noise, and the general racket of a busy harbor.\u003c\/p\u003e\n\u003cp\u003eThe numbers back it up. Together the pair puts out 113 decibels, which is plenty to get the attention of another skipper who isn't watching where they're going. That's the whole point of a good horn. You want to be heard the first time, whether you're signaling your intentions in a tight channel, warning off a boat drifting toward your bow, or just letting the marina know you're coming in.\u003c\/p\u003e\n\u003cp\u003eHella Marine built these to live outside. The trumpets ride in black ABS plastic housings that won't rust and won't fade the way a cheap chrome horn does after a season in the sun. The mounting hardware is galvanized metal, so the bracket itself holds up to salt air and spray instead of turning to a rusty mess behind your console. Hella Marine calls their gear fit and forget, and a horn is exactly the kind of part where that matters. You mount it once, wire it in, and you don't want to think about it again until you need it.\u003c\/p\u003e\n\u003cp\u003eWiring is straightforward for anyone comfortable with 12-volt DC work. The kit runs on a standard 12 Volt system and pulls about 72 Watts, which works out to roughly 6 amps of draw. Because of that current, we always tell people to wire a horn like this through a relay rather than running the full load through the dash button. The button triggers the relay, the relay feeds the horns, and your switch stays cool and lasts for years. A relay and the wiring aren't part of this kit, so grab those separately if you don't already have them on hand.\u003c\/p\u003e\n\u003cp\u003eMounting is flexible. The trumpets are 3.4 inches across at the mouth, compact enough to tuck into an engine compartment, under a gunwale, or behind a console where they're out of the weather but still free to project sound. Best practice on the water is to point the trumpet openings slightly downward so they drain and don't collect rain or spray. The galvanized bracket gives you a solid, adjustable base to set that angle. Keep both horns clear of anything that would muffle them and you'll get the full 113 decibels they're rated for.\u003c\/p\u003e\n\u003cp\u003eThis is a genuine dual-tone setup, not a single horn dressed up. You're getting two separate trumpets, the high-tone 500 Hertz unit and the low-tone 400 Hertz unit, plus the galvanized bracket to hang them. It's a common upgrade for boaters who are tired of a weak factory beeper, and it's just as at home on a center console, a cruiser, or a pontoon. Anywhere you've got 12 volts and a spot to mount them, these will give you a horn that actually sounds like it means it.\u003c\/p\u003e\n\u003cp\u003eA loud, reliable horn isn't just a nice-to-have either. Sound signals are part of the navigation rules, and there are times you're expected to make one, like backing out of a slip with limited visibility or signaling a turn in a narrow channel. A horn that other boaters can actually hear over their own engines makes those moments safer for everyone. The TC16 pair gives you that headroom, and the two-tone blend is easy to pick out from the higher-pitched single horns a lot of smaller boats run.\u003c\/p\u003e\n\u003cp\u003eOne honest note on what this is and isn't. It's a 12-volt electric trumpet horn kit, so it needs power from your battery or bus to work. It's not an air horn and doesn't need a compressor or tank. That keeps the install simple and the maintenance close to zero, which is exactly what you want from safety gear. Wire it right, mount it so it drains, and it'll be ready every time you reach for the button.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eDual-tone design pairs a 500 Hz high-tone and a 400 Hz low-tone trumpet for a full, layered blast that carries across a busy harbor\u003c\/li\u003e\n  \u003cli\u003e113-decibel combined output cuts through wind and engine noise so you're heard the first time\u003c\/li\u003e\n  \u003cli\u003e12 Volt operation wires straight into any standard boat electrical system\u003c\/li\u003e\n  \u003cli\u003e72 Watt \/ roughly 6 amp draw, wire it through a relay to protect your dash switch\u003c\/li\u003e\n  \u003cli\u003eBlack ABS plastic housings resist corrosion and won't rust or fade after a season in the sun\u003c\/li\u003e\n  \u003cli\u003eGalvanized metal mounting bracket stands up to salt air and spray\u003c\/li\u003e\n  \u003cli\u003e3.4 inch trumpets are compact enough to mount in an engine bay, under a gunwale, or behind the console\u003c\/li\u003e\n  \u003cli\u003eSet of 2 complete horns plus bracket, a genuine two-tone kit rather than a single unit\u003c\/li\u003e\n  \u003cli\u003eHella Marine TC16 series, part number 011225831, backed by the full manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this one horn or two?\u003c\/summary\u003e\n    \u003cp\u003eIt's a complete set of two.
