MOTORCYCLE HORN

Stock motorcycle horns are designed to meet minimum legal requirements, not to actually get you noticed in traffic. Most factory motorcycle horns produce around 100 to 110 decibels, which sounds adequate in a quiet garage but disappears against road noise, wind, and other vehicles. Upgrading to an aftermarket motorcycle horn is one of the simplest and most effective safety improvements you can make to your bike, and our HornBlasters Compact Electric Horn delivers 123.7 decibels in a package small enough to fit virtually any motorcycle.

WHY STOCK MOTORCYCLE HORNS ARE SO QUIET

Factory motorcycle horns are built to meet minimum sound requirements at the lowest possible cost. Manufacturers use small, low-power horns that draw minimal current from the bike's electrical system to keep things simple, lightweight, and inexpensive. The result is a horn that produces around 100 to 110 decibels, which sounds loud in a parking lot but is easily drowned out at highway speeds, in heavy traffic, or against engine and wind noise.

The problem is that other drivers, especially those in cars and trucks with sound-insulated cabins, often can't hear a motorcycle horn at all in real-world riding conditions. By the time a distracted driver finally notices you, the situation may already be dangerous.

A louder aftermarket motorcycle horn solves this problem by producing significantly more sound output, cutting through traffic noise and getting the attention of nearby drivers before they make a mistake.

WHAT TO LOOK FOR

Picking the right aftermarket motorcycle horn isn't just about finding the loudest one on the market. The horn needs to fit your bike, install without a major project, hold up to the elements, and actually be loud enough to make a difference in real riding conditions. The four features below are what separate a worthwhile motorcycle horn upgrade from a frustrating one, and they're exactly what we built into the HornBlasters Compact Electric Horn.

EASY INSTALLATION

With only a 12 Volt requirement this horn is easy and quick to install (additional wiring kit may be necessary for some models).

COMPACT SIZE

Small Compact size gives you the versatility of mounting this just about anywhere!

CRAZY LOUDNESS

Although this is an Electric Horn it still is significantly louder than the stock horn! Recordings do not do it justice, once you hear it you'll know!

WEATHER-RESISTANT

Engineered to brave the elements, our compact electric horn boats a robust weather-resistant build.

THE HORNBLASTERS COMPACT ELECTRIC HORN

The HornBlasters Compact Electric Horn is our purpose-built motorcycle horn, designed specifically to address the limitations of stock motorcycle horns while staying compact enough to fit virtually any bike.

The horn produces 123.7 decibels of attention-grabbing sound, significantly louder than any factory motorcycle horn. The dual-tone electric design delivers a sharp, commanding honk that cuts through traffic, road noise, and wind, ensuring your presence is heard even by drivers in sound-insulated vehicles.

At just 4.5 inches wide and 4.5 inches tall, the Compact Electric Horn fits in spaces where larger aftermarket horns won't, making it a true drop-in replacement for the factory horn on most motorcycles. The stealth black finish keeps the install looking clean, and the weather-resistant construction holds up to rain, dust, and the temperature extremes that come with daily riding.

The horn runs on the standard 12V electrical system used by virtually all motorcycles, and the included relay and harness allow it to tap directly into the existing factory horn wiring. For most riders, installation requires no modifications beyond mounting the horn and connecting the included components to your existing wiring.

INSTALLATION OVERVIEW

Installing the HornBlasters Compact Electric Horn is a straightforward DIY project that most riders can complete in under an hour, depending on the motorcycle. The horn is designed as an upgrade to the factory horn, mounting in the same general location and triggered by the same factory horn button. The included relay and harness handle the higher power requirements without overloading your motorcycle's existing wiring.

The basic installation process involves:

  1. Locating the factory horn on your motorcycle (usually mounted on the frame near the front of the bike)
  2. Disconnecting the factory horn wiring and removing the stock horn
  3. Mounting the Compact Electric Horn in the factory location or another suitable spot
  4. Wiring the included relay between the battery and the horn, then connecting the relay trigger wire to the factory horn wiring
  5. Testing the horn to make sure it works correctly

The included relay is necessary because the Compact Electric Horn draws 18 amps when active, which is more than most factory motorcycle horns. The relay handles the higher current draw by pulling power directly from the battery only when the horn button is pressed, while the factory horn button still triggers the horn through the relay. This setup protects your motorcycle's existing wiring from being overloaded while still letting you use the original horn button.

Riders who prefer to wire the horn standalone with a dedicated power line and switch can purchase the optional Wiring Kit, which includes additional components for a fully separate install. The Wiring Kit is not required for installation but offers an alternative for builds where tapping into the factory wiring isn't ideal.

FAQs

WHY CONSIDER AN AFTERMARKET MOTORCYCLE HORN?

Upgrading to an aftermarket motorcycle horn is primarily about enhancing safety and visibility on the road. Stock horns might not always capture the attention of other road users effectively, especially in noisy environments. An aftermarket horn typically offers a louder and more distinct sound, ensuring that your presence is noticed, potentially preventing accidents. This upgrade is a proactive step toward ensuring your safety by making sure you're heard when it matters most.

WHY IS MY MOTORCYCLE HORN SO QUIET?

Most factory motorcycle horns are designed to meet minimum legal requirements rather than to be heard over traffic, wind, and road noise. Stock horns typically produce around 100-110 decibels, which sounds adequate in a quiet environment but gets drowned out at highway speeds or in city traffic. The factory horn's small size, limited power draw from the motorcycle's electrical system, and budget-focused construction all contribute to the weak sound. An aftermarket motorcycle horn like our Compact Electric Horn produces 123.7 decibels, significantly louder than a stock horn while still using the existing 12V electrical system.

HOW LOUD SHOULD A MOTORCYCLE HORN BE?

A good aftermarket motorcycle horn should produce significantly more sound than a factory horn while staying within reasonable noise levels. Factory motorcycle horns typically produce 100-110 decibels, which is often inadequate for being heard in heavy traffic or at highway speeds. An ideal aftermarket motorcycle horn produces 115-125 decibels, loud enough to cut through road noise and traffic without being excessive. Our Compact Electric Horn produces 123.7 decibels, which is in the sweet spot for being noticeably louder than a stock horn while remaining a practical upgrade for everyday riding.

HOW DO I KNOW IF AN AFTERMARKET HORN WILL FIT MY MOTORCYCLE?

Most aftermarket motorcycle horns work with virtually any 12V motorcycle that has a factory horn, including Harley-Davidson, Honda, Yamaha, Suzuki, Kawasaki, Ducati, BMW, Triumph, KTM, Indian, Aprilia, Royal Enfield, Vespa, Surron, and most other major brands. The two main considerations are physical size (does the horn fit in the available space) and electrical compatibility (does the motorcycle's electrical system support the horn's amp draw). Our Compact Electric Horn is one of the smallest aftermarket horn options available, measuring just 4.5" tall, and includes a relay and harness that work with the existing factory horn button on most motorcycles.

HOW DOES THE COMPACT ELECTRIC HORN INSTALL ON MY MOTORCYCLE?

The Compact Electric Horn is designed to install in the factory horn location on most motorcycles, and it's triggered by the same factory horn button. The horn includes a relay and harness plug that handle the higher current draw (18 amps when active) without overloading your motorcycle's existing wiring. The relay pulls power directly from the battery only when the horn button is pressed, while the factory horn button still triggers the horn through the relay. The horn also features a molded mounting hole on the back with included hardware, giving you flexibility to mount it in alternate locations if the factory horn position isn't ideal for your build.

WILL AN AFTERMARKET MOTORCYCLE HORN DRAIN MY BATTERY?

A properly installed aftermarket motorcycle horn will not drain your battery during normal operation. The horn only draws power when it's actively being used, which is typically just a few seconds at a time. Our Compact Electric Horn draws 18 amps when active, more than a stock horn but well within what motorcycle batteries can handle for short bursts. The included relay ensures power is drawn directly from the battery only when the horn is activated, which protects your motorcycle's electrical system. As long as you don't hold the horn down for extended periods, battery drain isn't a concern.

IS THE COMPACT ELECTRIC HORN WEATHER-RESISTANT?

Yes, the Compact Electric Horn is weather-resistant and built to handle rain, dust, and the temperature extremes that come with daily riding. The durable construction and stealth black finish hold up to everything the road throws at it, though the horn isn't intended for full submersion.

DO I NEED TO BUY THE WIRING KIT WITH THE COMPACT ELECTRIC HORN?

No, the Wiring Kit is an optional accessory that's not required for installation. The Compact Electric Horn comes with the relay and relay harness needed for installation, which wires the relay between the battery and the horn while using the factory horn button as the trigger. The optional Wiring Kit is for riders who prefer to wire the horn standalone with a dedicated power line and switch rather than using the factory horn button. Most riders choose the standard install using the included components, which works on the majority of motorcycles.
