FARBIN 12V Car Horn Dual-Tone Loud Waterproof — Compact 130 dB, ABS Housing

This dual-tone auto horn from FARBIN combines a space-saving footprint with robust, weather-resistant construction so you can add a high-output warning signal to cars, trucks, ATVs and other 12V vehicles. Built with durable ABS housing, a metal mounting bracket and a sealed shell, the unit is designed to resist moisture and fit in tighter engine bays where larger horns won’t. It runs on a standard 12V DC supply, draws low power and provides a penetrating sound that helps attract attention without complex installation.

How loud is this horn and will drivers hear it in traffic?

The FARBIN 12V horn generates up to 130 dB at source using a dual-tone configuration that produces a fuller, more noticeable sound than single-tone horns. That intensity helps make the vehicle’s presence obvious in busy traffic or low-visibility conditions, while the combined tones improve localization for pedestrians and other drivers.

• Peak sound level: approximately 130 dB
• Dual-tone design for clearer, attention-grabbing sound
• Effective range suitable for urban and highway environments

Will it fit my vehicle and how easy is it to mount?

The horn is built with a compact form factor and includes a fixed iron mounting bracket so it fits a wide range of vehicles with limited installation space. It’s intended for 12V systems and commonly mounts in engine bays, under bumpers or on frames where space is tight.

• Compatible with most 12V cars, trucks, motorcycles, ATVs and karts
• Compact ABS housing for tight installation locations
• Includes metal bracket for secure attachment

What electrical requirements and wiring tips should I know?

This horn operates from a 12V DC supply and is engineered for low current draw while maximizing acoustic output. The kit uses a wiring harness and relay; correct connections ensure the relay functions properly and the horn sounds reliably.

• Operates on standard 12V DC power
• Low power consumption for efficient operation
• Important wiring note: follow the harness color guide—one button wire to the blue (or white) harness lead, the other to battery positive, and the white/blue harness lead to chassis ground—to avoid relay faults

How durable is the horn in wet or harsh conditions?

The FARBIN horn combines a waterproof shell and quality ABS material with a corrosion-resistant bracket, making it suitable for exposure to rain, splashes and road grime. While robust, seal integrity and proper mounting help extend service life in demanding conditions.

• Waterproof outer shell protects internal components
• High-quality ABS housing resists impact and weathering
• Iron mounting bracket for secure, long-lasting installation

Who this is for: The FARBIN Horn 12V suits drivers who need a powerful, space-efficient warning horn for passenger cars, light trucks, motorcycles, ATVs, karts and other 12V vehicles. It’s ideal for anyone upgrading a weak or single-tone factory horn, fitting an aftermarket vehicle with limited mounting room, or adding a weather-resistant horn for improved roadside visibility. Installers and DIYers will appreciate the low power draw and compact size, but should carefully follow the wiring guidance to ensure correct relay operation.
