Product Information

Full details

The PIAA Slender Dual Tone Horn is an ideal upgrade for motorcycle riders and automotive enthusiasts working with tight engine bays who need a loud, authoritative alert signal. By combining 400Hz and 500Hz frequencies to reach 112dB, it provides a powerful sound profile in a remarkably thin form factor, though users should be aware that this unit is designated for off-road use only and lacks E-mark certification.

Extended Product Information

FAQs

Is this horn street legal?

This product is designed for off-road use and is not E-marked, so it may not be compliant with local road safety regulations.

Can I install this on any vehicle?

Yes, it is designed for universal fitment, though you should verify there is space to mount the horns and ensure your wiring can handle the draw.

What is the decibel output?

The system produces 112dB, which is significantly louder than most factory motorcycle horns.

Does it come with a wiring harness?

The package includes the horn units; a relay or additional wiring harness may be needed depending on your vehicle's existing electrical system.

How do I maintain the horn?

The horn requires little maintenance, but you should periodically clear debris from the guard fin to ensure optimal sound projection.

Troubleshooting

The horn does not sound when button is pressed.

Check the fuse in your vehicle's fuse box and ensure all electrical connections are tight and free of corrosion.

The sound is muffled or quiet.

Verify that the horn's front opening is not obstructed by other components and ensure the protective guard fin is free of excessive mud or debris.

Horn makes a clicking sound but does not honk.

The power supply may be insufficient; verify that the wiring gauge is appropriate and consider installing a dedicated relay for a direct battery feed.

Pros and Cons

Pros

  • Extremely slim profile fits in tight spaces where standard horns fail
  • Strong 112dB output provides excellent safety and alerts
  • Integrated water and dust protection increases lifespan
  • Dual-tone harmonic sound is more noticeable than single-tone factory horns

Cons

  • Not E-marked and intended for off-road use only
  • May require aftermarket wiring harness depending on vehicle stock setup
  • Higher pitch might not match the deep bass tone preferred by some vehicle owners

Setup, Compatibility & Care

Installation is designed to be straightforward, utilizing existing mounting points on most vehicles. Before starting, ensure you have disconnected the vehicle battery to prevent short circuits.

  1. Locate the existing horn and disconnect the factory wiring.
  2. Mount the PIAA units using the integrated brackets.
  3. Connect the new horns to the existing wiring; if the existing wiring is insufficient for the amperage draw of a dual-tone system, an external relay and fused harness are recommended.
  4. Ensure the guard fin is facing downward or away from direct road spray to maximize the effectiveness of the weather protection.

Care is minimal; simply wipe the guard fin occasionally to prevent debris buildup that could muffle the sound output.
