MIRKOO Backup Alarm 110dB 12–80V DC Waterproof Industrial Reverse Siren — 2‑Pack, Heavy‑Duty Beeper

The MIRKOO Backup Alarm is a waterproof, heavy-duty 110dB reverse warning siren designed to fit 12–80V vehicles and warn bystanders while reversing.

This compact, industrial-grade backup alarm delivers a loud, recognizable beeper tone built for commercial trucks, vans, lorries and other heavy vehicles. Constructed from durable materials and rated for wide voltage compatibility, it steps up vehicle safety by sounding a clear 110dB alert whenever the vehicle is put into reverse. The unit is supplied as a two-piece set and is engineered for simple wiring to the reverse-light circuit, making it a practical upgrade for fleets, work trucks and equipment that operate in noisy or confined environments.

How loud is the alarm and will people hear it in noisy areas?

The MIRKOO alarm produces approximately 110dB (±3dB), which is significantly louder than typical vehicle horns and many ambient worksite noises. That sound level is chosen to cut through background noise and draw attention to reversing activity without relying on visual signals alone.

• Rated sound pressure: 110dB ±3dB for strong audible warning
• Distinct beeper tone that is easy to recognize as a reversing signal
• Suitable for busy loading docks, construction sites and noisy streets

What vehicles and voltages are compatible with this backup alarm?

This alarm is built to operate across a broad DC range so it works on most commercial and consumer vehicles. It auto-adjusts to vehicle electrical systems between 12 and 80 volts DC, so one model fits many trucks, vans, freight vehicles, SUVs and industrial machines.

• Voltage compatibility: automatic adjustment from 12V to 80V DC
• Fits: light trucks, heavy trucks, vans, lorries, SUVs, and off-road equipment
• Universal wiring method for integration with reverse light or reverse switch

Is installation difficult and what wiring is required?

Installation is straightforward for anyone comfortable with basic vehicle wiring. The alarm connects to the reverse-light circuit or an existing reverse switch and requires a ground connection; no special tools are normally needed beyond basic splicing and fastening hardware.

• Connect positive lead to reverse light power or dashboard reverse switch
• Splice negative lead to vehicle ground (chassis or negative terminal)
• Mount with supplied hardware in a protected, visible location on the rear of the vehicle

How durable and weather-resistant is the unit for outdoor use?

The MIRKOO alarm is constructed from premium materials to withstand rough service conditions and a wide range of temperatures. It is designed to resist moisture and road grime, so it can operate reliably in hot or cold climates and in wet weather.

• Waterproof construction for outdoor and roadside use
• Built to resist dust, vibration and temperature extremes
• Low current draw with long operational life for fleet applications

Who is this for: The MIRKOO 110dB Backup Alarm (2-pack) is ideal for fleet managers, contractors, delivery drivers and equipment operators who need a durable, high-decibel reversing warning that installs quickly and works across a wide voltage range. If you operate vehicles in noisy environments, tight work zones, or frequently back up near pedestrians and co-workers, this alarm helps increase audible visibility without complex electronics or vehicle-specific modules.
