FARBIN Truck Back-Up Alarm 110dB Reverse Horn — IP67 Weatherproof, 12–48V Universal Mount

FARBIN Truck Back Up Alarm is a durable, IP67-rated reverse warning horn that emits a 110±3 dB alert to warn pedestrians and drivers when heavy vehicles are backing up.

This rugged backup alarm is designed for heavy-duty and commercial vehicles that need a loud, weatherproof reversing signal. Built from reinforced nylon with epoxy-embedded electronics, the unit resists dust, water and extreme temperatures from -30°C to 80°C. It runs on 12–48V systems, includes reverse-polarity protection, and ships with a universal mounting bracket for flexible placement on trucks, vans, construction machines and other large vehicles.

How loud is the FARBIN backup horn and why does that matter?

The alarm produces a continuous beeping sound measured at 110±3 dB — strong enough to cut through traffic noise and construction site ambient sound. A louder signal increases the chance that nearby pedestrians and drivers will notice the vehicle’s movement, helping to reduce close-call situations.

• 110±3 dB output for clear audibility over long distances
• Consistent tone designed to attract attention in noisy environments
• Suitable for busy job sites, loading docks and urban streets

Will this unit survive harsh weather and rough use?

Yes. The housing is made from high-quality nylon and the electronics are protected with epoxy, giving the alarm IP67-rated dust and water resistance. It is engineered to perform reliably in temperatures from -30°C to 80°C, making it suitable for extreme cold, heat and wet conditions.

• IP67-rated housing resists dust and immersion
• Epoxy-embedded circuitry protects against vibration and moisture
• Durable nylon shell stands up to physical wear and exposure

Which vehicles is the FARBIN reverse alarm compatible with?

The alarm is universal across 12V–48V electrical systems, so it fits most heavy-duty and commercial vehicles. Typical applications include trucks, buses, vans, pickups, forklifts, excavators, semi-trailers, RVs and other special-purpose machines.

• Works on 12V to 48V systems for broad compatibility
• Commonly used on trucks, construction equipment and commercial fleets
• Universal mounting bracket with slotted holes for flexible installation

How difficult is installation and what protections are included?

Installation is straightforward: connect the positive terminal to a reverse light or switch and the negative to ground. The unit includes reverse-polarity protection, so it is guarded against accidental miswiring and will activate automatically when reverse lights energize.

• Simple two-wire hookup to reverse light circuit
• Reverse polarity protection prevents damage from incorrect wiring
• Universal bracket allows mounting in multiple positions on the vehicle

Who is this for: The FARBIN Truck Back Up Alarm is built for fleet managers, construction crews, delivery drivers and vehicle owners who need a dependable, high-decibel reversing warning that tolerates heavy use and harsh environments.
