The MIRKOO Backup Alarm is a heavy-duty, waterproof 110dB reverse warning beeper that connects to 12–80V DC vehicles to provide a loud, reliable alert while reversing.

Compact and robust, this industrial-grade backup alarm is built for commercial and personal vehicles that need a clear audible warning when backing up. Engineered from durable materials and designed for simple installation, the unit adapts automatically across a wide voltage range so it works with pickups, vans, lorries, tractors and many types of heavy equipment. It offers a high-decibel tone that remains distinct in noisy outdoor environments and is sealed for weather resistance.

How loud is the MIRKOO backup alarm and where will I hear it?

The unit produces approximately 110 dB (±3 dB), loud enough to cut through ambient noise on construction sites, loading docks and busy streets. That level is intended to ensure pedestrians and nearby workers can notice reversing vehicles even in crowded or noisy situations.

• Rated output: 110 dB (±3 dB)
• Designed to be audible across typical outdoor work distances
• Consistent tone for clear recognition

Will this alarm work with my vehicle's electrical system?

The MIRKOO alarm automatically accepts 12–80V DC input, so it fits most light- and heavy-duty vehicles without a separate voltage converter. It triggers from the reverse-light circuit or a dashboard-mounted reverse switch and uses a simple two-wire connection for power and ground.

• Universal fit for 12–80V DC systems
• Splice red lead to reverse light or reverse switch
• Connect black lead to vehicle ground (negative)

• Waterproof housing suitable for exterior mounting
• Low current draw to minimize strain on vehicle electrical system
• Construction suited for a wide temperature range and regular outdoor use

How difficult is installation and what comes with the product?

Installation is straightforward for anyone comfortable with basic vehicle wiring. The alarm ships equipped with two pre-attached wires for quick splicing to the reverse circuit and ground; no special tools or electronic modules are required.

• Pre-wired with positive (red) and negative (black) leads
• Splice-in connection — no relay or fuse required for typical installations
• Compact mounting footprint works on many vehicle exteriors
