A-Premium 2-Pack Disc Horns 12V High & Low Tone Waterproof 110 dB Compact Round Set

A-Premium 2-pack disc horns are universal, waterproof 12V electric horns that deliver a paired high-and-low tone up to 110 dB for clear, reliable vehicle signaling.

These compact round horns are engineered to replace factory horns on cars, trucks, motorcycles, scooters and specialty vehicles. Constructed from electroplated iron and ABS plastic, the set includes two complementary frequencies (high and low) to produce a fuller, more attention-grabbing sound. Designed for straightforward installation and weather resistance, they suit drivers who want a louder, durable horn without complicated wiring or modifications.

How loud are these horns and what frequencies do they use?

The pair produces sound levels in the 105–118 dB range with a typical listed value near 110 dB, loud enough to be noticed in traffic while remaining compact. The two horns work together to create a tonal blend that improves audibility over single-element horns.

• Nominal volume range: 105–118 dB
• Combined output commonly approximates 110 dB
• High tone frequency: about 420 ± 30 Hz
• Low tone frequency: about 350 ± 30 Hz

Will these horns fit my vehicle and how easy is installation?

They are designed as universal direct-fit replacements compatible with most 12V systems used in cars, trucks, motorcycles and scooters. The mounting points and wiring are standardized to make swap-in installation quick; basic tools and a simple wiring connection are typically all that’s required.

• 12 V electrical system compatibility
• Diameter: 123 mm — matches common horn mounting locations
• Simple two-terminal wiring using included copper plugs
• Solid structural design reduces risk of loosening during drives

How durable are they in wet or corrosive conditions?

The horns use electroplated iron and ABS plastic to resist corrosion and shed water, so they maintain function across varied weather. Copper plugs improve electrical conductivity and support consistent performance over time, helping the horn remain reliable in rain and damp environments.

• Electroplated iron housing for corrosion resistance
• ABS plastic components add impact and weather tolerance
• Copper electrical connectors for better conductivity
• Rated to operate normally across typical outdoor conditions

What electrical load do these horns draw and are they safe for standard circuits?

Each horn draws up to about 4.5 A at 12 V, which fits within the capacity of most factory horn circuits or relay-protected installations. If your vehicle’s original horn circuit is weak, using a relay is a common and simple way to ensure reliable power delivery.

• Voltage: 12 V nominal
• Current per horn: ≤4.5 A
• Works with standard horn relays or direct factory connections
• Recommended: use relay if original circuit is underpowered

Who is this for: Drivers and vehicle owners who need a dependable, louder horn without major modifications — including car and truck owners, motorcycle and scooter riders, fleet managers and anyone replacing a worn or weak factory horn. The A-Premium pair suits people who prioritize easy installation, weather resistance and a clear high-and-low dual tone for improved on-road audibility.
