MIRKOO Backup Alarm 110dB 12–80V DC Heavy-Duty Waterproof Reverse Warning for Trucks – Compact Durable Beeper

MIRKOO Backup Alarm is a compact, heavy-duty 110 dB reverse warning horn that runs on 12–80V DC and alerts pedestrians and workers when a vehicle is reversing.

This durable backup alarm was built for commercial vehicles, construction machines, and fleet use where a loud, reliable reverse warning is needed. Engineered for harsh conditions, it combines an unmistakable beeper tone with universal voltage compatibility and straightforward wiring so you can fit it to trucks, vans, lorries, and other heavy vehicles quickly.

How loud is the alarm and why does that matter?

The unit produces a 110 dB (±3 dB) signal, loud enough to be heard over traffic, engines, and site noise without being distorted. A consistent, high-decibel tone increases safety by ensuring the reversing warning is noticed by pedestrians and nearby workers.

• Measured output: approximately 110 dB for clear audibility
• Stable tone that resists muffling in noisy environments
• Designed to maintain output across typical vehicle electrical systems

Will it work with my vehicle's electrical system?

The MIRKOO alarm accepts a wide DC range from 12V up to 80V and automatically adapts, so it fits most light- and heavy-duty vehicles without additional converters. Low current draw reduces strain on vehicle wiring while remaining compatible with standard reverse-light circuits or dedicated reverse switches.

• Voltage range: 12–80 V DC for universal vehicle fit
• Connects to reverse light positive (red) and ground (black)
• Automatic voltage adjustment; no external regulator required

How easy is installation and what wiring is needed?

Installation is straightforward and designed for field or shop wiring: splice the red wire to the reverse lamp or reverse switch positive, and attach the black wire to vehicle ground. No special tools or complex programming are required, letting mechanics or fleet technicians fit it quickly.

• Simple two-wire hookup: red to reverse circuit, black to ground
• Compatible with standard vehicle reverse switches and lights
• Compact housing simplifies mounting on bumpers or chassis

Is the alarm built for tough outdoor use?

Yes — components and housing are chosen for longevity in demanding climates, from hot sun to freezing conditions. The unit resists moisture and dust so it performs reliably on job sites, docks, and highways where exposure is common.

• Rugged construction resists vibration and road debris
• Sealed design reduces risk from water and dirt ingress
• Materials and assembly aimed at long service life under heavy use

Who is this for: MIRKOO Backup Alarm is intended for fleet operators, contractor mechanics, and vehicle owners who need a dependable, high-volume reverse warning for trucks, vans, lorries, SUVs, and work machines. It's well suited to construction sites, delivery vehicles, municipal fleets, and any situation where a loud, clear reverse alert improves safety and compliance.
