FARBIN Truck Backup Alarm 12–48V 110dB IP67 Weatherproof Reverse Warning Horn

FARBIN Truck Back up Alarm is a heavy-duty, IP67-rated reverse warning horn that delivers a 110±3 dB beeping sound for 12–48V trucks, vans, forklifts and construction vehicles.

This compact backup alarm combines rugged, weatherproof construction with simple wiring to add audible reversing alerts to commercial and large vehicles. Designed to cut through ambient noise, the unit uses epoxy-embedded electronics and a nylon housing to withstand water, dust and extreme temperatures from -30°C to 80°C. It’s built for universal fitment and everyday use on work sites, in yards, and on the road.

How loud is the alarm and where will it be heard?

The alarm emits an intense 110±3 dB beeping tone designed to attract attention across noisy environments without ambiguity. That volume helps alert pedestrians and other drivers during reversing maneuvers, especially on job sites and busy loading areas.

• Rated output: 110 dB ±3 dB for immediate recognition
• Pitch and tone optimized for human attention in traffic
• Effective over greater distances compared to lower-decibel units

Will this unit survive rough environments and bad weather?

Yes — the alarm is built for harsh conditions with IP67-level protection and epoxy-sealed electronics. The durable nylon housing resists dust ingress and temporary immersion, while components operate across a wide temperature range.

• IP67 waterproof and dustproof rating for outdoor use
• Epoxy-embedded electronics reduce moisture damage risk
• Operational from -30°C to 80°C for extreme climates

Is installation difficult and which vehicles are compatible?

Installation is straightforward for any technician who can splice into a reverse-light circuit. The alarm supports 12–48V systems and comes with a universal mounting bracket to fit trucks, trailers, buses, forklifts and construction gear.

• Compatible with 12V–48V heavy-duty and commercial vehicles
• Universal slotted bracket for adaptable mounting positions
• Reverse-polarity protection prevents damage if wired incorrectly

What safety or maintenance tips should I follow?

Position the alarm so its sound projects toward the rear unobstructed by bodywork, and confirm wiring is secure and protected from abrasion. Periodic checks ensure the unit remains sealed and the bracket is tight for reliable long-term performance.

• Mount with clear rear-facing path for optimal audibility
• Splice to reverse light or switch; ground to vehicle chassis
• Inspect seals and bracket during routine vehicle maintenance
