Product Information
Full details
The Hella Trumpet Horn (3PB 005 411-001) is designed for heavy-duty vehicles, such as trucks and buses, that feature an existing on-board air brake system. It offers exceptional safety through a piercing dual-tone acoustic output that ensures drivers are heard in busy traffic conditions; however, it is strictly intended for pneumatic systems and will not function on standard passenger vehicles without a dedicated compressed air source.

Extended Product Information
FAQs
Can I install this on a regular car?
No, this horn requires a pneumatic air source (like an air brake system) to operate. It will not work on standard 12V electrical horn systems alone.
What is the operating pressure range?
The horn operates effectively within a pressure range of 4 to 8.5 bar.
Is this horn street legal?
Yes, the Hella 3PB 005 411-001 is ECE approved (R28), meeting European standards for acoustic signaling devices.
What frequencies does the horn produce?
The dual-tone design produces frequencies of 300 Hz and 350 Hz.
Does it come with mounting hardware?
Yes, the assembly includes the necessary accessories for pipe-neck mounting.
How do I maintain the chrome finish?
Regularly wash with clean water and mild soap to remove road grime and salt, then wipe dry to prevent water spotting.
Troubleshooting
Horn produces a weak or distorted sound
Check that air pressure is within the 4-8.5 bar range and ensure the air supply line has no kinks or obstructions.
No sound when triggered
Verify the electrical connection at the blade terminal and ensure the solenoid valve is receiving the correct voltage to release the air.
Air leaking from the horn unit
Inspect the pipe-neck connection and air fittings for loose seals. Use thread sealant if necessary on the pneumatic connections.
Pros and Cons
Pros
- Piercing 115 dB(A) volume for enhanced safety
- High-quality chrome-plated finish for aesthetic durability
- ECE R28 approved for legal road use
- Dual-tone output provides a clear, unmistakable warning signal
Cons
- Requires an existing pneumatic (air brake) system
- Not compatible with standard electric-only vehicle horn circuits
- Installation requires specialized air-line plumbing knowledge
Setup, Compatibility & Care
Installation requires mounting the horn to a secure, vibration-resistant surface using the provided pipe-neck mount. Ensure that the air supply line is securely connected and free of leaks, as pressure drops can negatively affect the acoustic output. The horn uses a standard blade terminal plug for the electrical trigger. Periodically inspect the chrome bells for debris or moisture buildup to maintain tone clarity. Ensure that the air supply is filtered to prevent contaminants from reaching the internal pneumatic valves. If the unit is exposed to heavy road salt, rinse the chrome surfaces with fresh water to maintain the finish.
