Best Horn For Harley Davidson: Compare 9 Horn Options

#1 · Best Overall

1. Kleinn HOGKIT-1BK

• Compatible with Vehicle Type: Motorcycle

Best for: Cowbell-cover Harley air-horn kit.

Why it ranks #1: Made for 1978-and-later Harleys with a classic cowbell cover, this direct-drive kit reuses the factory cover and includes bracket, wiring, relay, and hardware.

Kleinn’s HOGKIT-1BK replaces the factory horn assembly while reusing the factory Cowbell-style cover, giving compatible Harley riders a complete air-horn system with a clean installed appearance. Its direct-drive compressor is tankless, and the included custom bracket, wiring, relay and air line support a bundled installation.

The stated fit is for 1978-and-later Harley Davidson motorcycles with the classic Cowbell-style horn cover, a useful boundary for checking compatibility before choosing the kit. Reusing that cover avoids replacing it as part of the listed system. The dual air horn pairs with a compact, tankless direct-drive compressor, while the included bracket, wiring, relay, air line, hardware and instructions provide the main installation components. At six pounds and 15 by 10 by 9 inches, the kit is a substantial assembly to plan around.

Skip it if you have a Harley side-mounted horn rather than a Cowbell cover; Eagle Lights ELH-C lists side-mount direct replacement fit.

This suits owners of compatible 1978-and-later Harleys who want a complete dual air-horn system while retaining the Cowbell cover. The cover style is a firm fit boundary, and the listed kit dimensions merit installation-space planning.

#2 · Best Side-Mount Fit

2. Eagle Lights ELH-C

• Compatible with Vehicle Type: Motorcycle
• Material: Aluminum, Stainless Steel

Best for: Harley side-mount direct replacement.

Why it ranks #2: Designed for Harley models with side-mounted horns, it offers a 120 dB output and direct plug-and-play replacement installation.

Eagle Lights specifies this 120 dB SONICSHIELD horn for Harley Davidson models with side-mounted horns, and its direct plug-and-play replacement format can simplify swapping an existing unit. The chrome finish gives the replacement a distinct appearance, while the stated model-specific mounting position narrows the intended fit.

The direct plug-and-play description means the horn is intended to connect in place of an existing unit rather than requiring a separate compressor system. Its 120 dB rating provides the stated warning output, and the fit is specifically limited to Harley Davidson models with side-mounted horns. Aluminum and stainless steel are listed materials, while the chrome finish offers a visual match consideration for the motorcycle. Riders with a different horn location should not treat the general Harley label as universal fitment.

Skip it if you have a 1978-or-later Harley with a classic Cowbell cover and want a complete kit; Kleinn HOGKIT-1BK lists that fit.

This is suited to Harley owners replacing a side-mounted factory horn who want a direct plug-and-play format and chrome finish. Confirm that the motorcycle uses the specified side-mount position; the listing does not claim universal Harley fit.

#3 · Loudest Listed

3. Rivco AHHD

• Voltage: 12 V
• Compatible with Vehicle Type: Motorcycle

Best for: Chrome dual-trumpet Harley setup.

Why it ranks #3: Its dual-trumpet system is listed at 128 dB and includes a compressor, relay, wiring, mounting hardware, and dust and debris covers.

Rivco’s waterproof dual-trumpet air horns deliver a stated 128 dB warning blast, giving Harley riders a high-output replacement for the stock horn. The set includes a compressor, relay, wiring, mounting hardware and chrome-plated trumpets, while cone-shaped covers help shield the horns from dust and debris.

The air compressor creates instant pressure for the trumpets and can mount under the seat, behind the right side cover or on the frame down tube, with position varying by model. That flexibility helps accommodate different motorcycle layouts, though it makes the installation location model-dependent. The included relay, wiring, hoses, hardware and instructions support a complete setup, and the dust-and-bug covers add protection around the trumpets. At 11.5 by 9.75 by 6.5 inches and 4.8 pounds, the assembly needs room and support.

Skip it if you want an integrated compact horn assembly; DENALI SoundBomb Compact combines its compressor and acoustic unit in one assembly.

This suits Harley owners seeking chrome dual trumpets, a compressor and a strong stated warning output in one package. Plan around the assembly’s dimensions and model-dependent compressor placement before selecting an installation location.

#4 · Best Under-Cover Fit

4. Screaming Banshee Mini Banshee

• Voltage: 12 V
• Compatible with Vehicle Type: Motorcycle
• Material: Metal, Stainless Steel

Best for: Compact high-output motorcycle upgrade.

Why it ranks #4: The 126 dB motorcycle horn is specified to fit under Harley, Indian, and metric OEM horn covers, though exact Harley model fit is not detailed.

The Mini Banshee’s 126 dB output pairs a compact 3.5-inch-cube form with a louder warning signal than most American and metric OEM horns, according to its listing. That combination suits riders seeking more audible presence without moving to a larger air-horn assembly, including cruisers and sport bikes.

At 3.5 inches on each side and 12 volts, the Mini Banshee gives motorcycle owners a compact electrical-horn option with defined dimensions for planning a mounting location. Its stated fit covers cruisers, mid-size and sport bikes, and it fits under HD, Indian and metric OEM horn covers, which can preserve a covered-horn arrangement. The 126 dB rating is the key warning-output distinction. Stainless steel and metal construction are specified; the listing does not include a detailed installation-parts inventory.

Skip it if you need an included full air-horn installation kit; Kleinn HOGKIT-1BK lists its bracket, wiring, relay, air line and hardware.

This is a fit for Harley riders wanting a compact, high-output motorcycle horn that can sit under an OEM-style cover. Its listed dimensions and stated cover fit are useful checks, but installation components are not itemized.

#5 · Best Dual-Tone Option

5. DENALI SoundBomb Compact

• Voltage: 12 V
• Compatible with Vehicle Type: Motorcycle
• Material: Plastic

Best for: Compact CANbus-aware motorcycle horn.

Why it ranks #5: This compact 120 dB dual-tone motorcycle air horn includes a 30-amp relay and mounting hardware, with CANbus compatibility when appropriately wired.

DENALI combines the compressor and acoustic unit into one compact assembly, simplifying installation compared with a setup of separate components. The 12V SoundBomb produces a stated 120 dB dual-tone output, and its CANbus compatibility gives riders with CANbus-equipped motorcycles a specific wiring pathway when appropriate components are used.

The integrated electro-pneumatic assembly reduces the number of separate horn units to position, while included mounting hardware and a 30-amp relay support installation on compatible motorcycles. Its dual-tone 120 dB output provides the specified audible presence, and the 12V rating defines its electrical requirement. CANbus use is conditional: DENALI says appropriate wiring components are needed. The product is listed for motorcycles, but the supplied facts do not identify a Harley model-specific mounting location or direct-fit claim.

Skip it if you need an explicitly Harley side-mount plug-and-play horn; Eagle Lights ELH-C lists that direct replacement fit.

This fits riders seeking a compact dual-tone motorcycle air horn, particularly where an integrated assembly and CANbus pathway are useful. Harley-specific direct fit is not stated, and CANbus installation depends on suitable wiring components.

6. HELLA Motorcycle Disc Horn

• Voltage: 12 V
• Compatible with Vehicle Type: Motorcycle, Passenger Car
• Material: Acrylonitrile Butadiene Styrene (ABS), Alloy…

Best for: Simple 12V disc-horn replacement.

Why it ranks #6: A 12V universal-fit motorcycle disc horn with a compact listed size, but the supplied details do not specify Harley model fit or sound output.

HELLA’s 12V motorcycle disc horn comes in a compact 4.5-by-1.6-by-5.8-inch package, giving Harley owners a defined size to compare with an existing horn location. Its single-horn format keeps the setup simple, and the listed motorcycle compatibility makes it a general replacement candidate rather than a model-specific Harley kit.

The slim 1.6-inch dimension can help when checking clearance around a motorcycle’s existing horn position, while the stated 12V supply identifies its electrical category. HELLA lists compatibility with motorcycles and passenger cars, so it is not restricted to one vehicle class. The package includes the horn only; buyers should account for their existing mounting and wiring arrangement rather than expect a complete installation kit. Its ABS, alloy steel, plastic and stainless steel materials are specified, with no sound-level figure provided.

Skip it if you want a documented 120 dB Harley side-mount replacement; Eagle Lights ELH-C lists both Harley side-mount fit and its sound output.

This fits a Harley owner looking for a basic 12V disc horn and able to reuse or source the needed mounting and wiring pieces. Compare its listed dimensions with the available space; Harley-specific fit is not stated.

#7

7. FARBIN FB-S11

• Voltage: 12 V
• Compatible with Vehicle Type: Truck, Passenger Car, Motorcycle, Golf Cart…
• Material: Acrylonitrile Butadiene Styrene (ABS), Copper

Best for: High-output compressor horn seekers.

Why it ranks #7: This 12V horn is listed for motorcycles and includes a relay harness, but it has no stated Harley-specific mounting fit and its 150 dB figure uses a 2 m test distance.

FARBIN states a 150 dB test result measured two meters in front of the horn, giving this 12V motorcycle-compatible air horn a clearly specified attention-getting claim. Its upgraded compressor uses a red copper coil and responds quickly, while the listing says no vehicle air source is needed.

The included relay harness and installation parts support a wired setup, while the upgraded compressor means the horn does not rely on an air source already fitted to the motorcycle. That distinction may matter to Harley owners without an onboard air system. The 150 dB figure is tied to a stated test distance of two meters, rather than left without measurement context. ABS and copper are listed materials, and compatibility also covers cars, trucks, boats and other vehicle types.

Skip it if you require a stated Harley direct replacement; Eagle Lights ELH-C specifically fits Harley models with side-mounted horns.

This suits a rider seeking a compressor-based 12V warning horn without adding a separate vehicle air source. The broad motorcycle compatibility is stated, but Harley-specific mounting dimensions and direct-fit details are not provided.

8. YTFRL 300DB Snail Horn

• Compatible with Vehicle Type: Motorcycle, Truck
• Material: Metal, ABS

Best for: Weather-exposed 12V replacement.

Why it ranks #8: The 12V snail horn lists motorcycle compatibility and a 105–115 dB range, but the listing does not establish Harley-specific fitment.

A 12V snail horn rated at 105–115 dB gives Harley riders a compact replacement option with a stated warning output for noisy traffic. Its ABS housing and steel fixing hardware add impact and corrosion resistance, while the included mounting bracket and nut provide the listed mounting pieces for installation.

The 4.25-by-3.68-inch snail format offers a defined package size to consider when space around a Harley’s horn mount is limited. Its 12V rating and motorcycle compatibility identify the electrical and vehicle categories it supports, while the included bracket and nut supply basic mounting hardware. The ABS housing is described as resistant to impacts and abrasions, and the steel fittings resist rust and corrosion, useful qualities for a horn exposed to changing weather. The listing includes one horn assembly.

Skip it if you want a documented Harley-specific plug-and-play replacement; Eagle Lights ELH-C is listed for side-mounted Harley horns.

This suits a rider seeking a straightforward 12V snail-horn replacement with weather-resistant housing and supplied mounting hardware. Check the available mounting space against its listed dimensions; Harley-specific direct-fit compatibility is not stated.

9. OFBAND Motorcycle Horn Speaker

• Voltage: 12 V
• Compatible with Vehicle Type: Car, Bike, ATV, Truck, Scooter
• Material: Metal

Best for: Small-format 12V warning horn.

Why it ranks #9: This 12V, 105 dB horn is listed for bikes and several other vehicles, but no Harley-specific compatibility or mounting details are provided.

At 3.8 by 2.58 by 1.25 inches, OFBAND’s metal motorcycle horn offers a notably defined compact footprint for riders checking space near a Harley’s existing horn mount. Its 12V operation and stated 105 dB output provide the basic electrical and warning specifications for a simple replacement decision.

The metal construction and small listed dimensions make this a practical option to compare against a constrained mounting area, while its 12V rating identifies the required electrical category. OFBAND describes its articulation chamber as producing a clear warning sound for noisy urban settings, and gives a 105 dB output figure. Compatibility is listed for bikes as well as cars, ATVs, trucks and scooters. The included component is one horn, so the listing does not describe a dual-trumpet system or a complete air-horn kit.

Skip it if you want a complete Harley air-horn kit with compressor and brackets; Rivco AHHD lists those components.

This suits a Harley rider wanting a compact, metal 12V horn and checking dimensions against an existing mount. It is a single horn rather than a listed compressor-and-trumpet package, so consider that boundary before choosing.
