HELLA eLONG-LIFE Trumpet 12V TE40 Electric Horn — Chip-Based Dual Tone Horn Set with 3-Year Replacement Warranty

The HELLA eLONG-LIFE Trumpet TE40 is a 12V electronic dual-tone horn set built for drivers who want a louder, clearer sound and a horn that won't quit after a year of daily honking. Unlike conventional horns that rely on a mechanical solenoid and diaphragm to create sound, the TE40 uses an electronic circuit — a chip-based switching mechanism — to generate its tone. That single design change removes the moving mechanical contact point that wears out in cheap horns, which is why HELLA can back this horn with a 3-year replacement warranty and a genuine "Fit & Forget" promise.

Why Choose the HELLA TE40 Over a Cheap Horn

• Electronic, chip-based switching mechanism — no mechanical wear point to fail over time
• Powerful, harmonic dual-tone sound: 112 dB(A) at 2m across 400Hz (low) and 500Hz (high)
• Backed by a 3-year replacement warranty, made possible by the wear-free electronic design
• Weather-resistant, dustproof housing rated for -40°C to 90°C operating range
• ECE-approved output, so sound levels are genuine and road-legal, not inflated marketing numbers
• Consistent tone quality over its lifespan — no rasping or fading like mechanical horns develop with age

What Problem It Solves

Most inexpensive horns rely on a mechanical solenoid that physically vibrates a diaphragm to make sound. That constant mechanical contact is exactly what wears out — contacts pit, springs fatigue, and the horn eventually turns weak, crackly, or stops working entirely, often within a year or two. The HELLA TE40 solves this at the design level: it replaces the mechanical switching mechanism with an electronic component, so there's no moving contact to degrade. The result is a horn that sounds the same on day one as it does years later, and a warranty that reflects that reliability.

Ideal For

• Drivers who want a genuinely loud, clear dual-tone horn upgrade over a factory-fit or generic horn
• Cars, SUVs, and universal-fit vehicles needing a reliable 12V horn set with OE-style mounting
• Anyone who's replaced a cheap horn more than once and wants a long-term, warrantied fix

Not intended for 24V heavy commercial vehicles — check your vehicle's voltage before ordering, and confirm mounting clearance for the trumpet-style horn bodies before installation.

How to Install

1. Disconnect the vehicle battery before starting any electrical work.
2. Mount both horns using the included fixing bracket and M8 screw holder, choosing a location with clear airflow and away from direct road spray.
3. Wire the horns through a relay, using the existing horn feed or a new relay circuit rated for the horn's power draw (48W per horn).
4. Reconnect the battery and test both high and low tone horns for correct sound and secure mounting.
5. Recheck all connections after a short test drive to confirm nothing has loosened from vibration.

What's Included

1 x HELLA eLONG-LIFE Trumpet 12V TE40 Electric Horn Set (2 pieces — high tone & low tone), with mounting bracket

Precautions

• Confirm your vehicle runs on 12V before purchase — this horn set is not compatible with 24V systems
• Always wire through a relay to protect your vehicle's horn switch and wiring from the horn's current draw
• Disconnect the battery before installation to avoid short circuits or accidental horn activation
• Mount securely using the supplied bracket — loose mounting can affect tone and cause premature wear

HELLA TE40 Electronic Horn vs. Regular Mechanical Horn

Frequently Asked Questions

Why is the HELLA TE40 more expensive than a regular horn?
It uses an electronic, chip-based switching mechanism instead of a mechanical solenoid, which removes the main wear point found in cheap horns — that's what allows HELLA to back it with a 3-year replacement warranty.

What does "chip-based" or "electronic" horn actually mean?
Instead of a moving mechanical contact vibrating a diaphragm, an electronic circuit generates the tone directly, so there's no mechanical part to wear out or fail over time.

Is this horn compatible with my car?
The TE40 is a 12V universal-fit horn set suitable for most cars, SUVs, and light vehicles. Confirm your vehicle uses a 12V electrical system before ordering.

Does it come with a warranty?
Yes, it comes with a 3-year replacement warranty, made possible by the horn's wear-free electronic design.

How loud is the HELLA TE40?
It produces 112 dB(A) at 2 metres, with a dual tone across 400Hz (low) and 500Hz (high), and is ECE-approved.

Do I need a relay to install this horn?
Yes, it should be wired through a relay to protect your vehicle's wiring and horn switch from the current draw (48W per horn).

Will the sound quality fade over time like cheap horns?
No — because there's no mechanical contact wearing down, the tone stays consistent over the horn's lifespan, unlike mechanical horns that often turn weak or crackly with age.

What's included in the box?
One set of two horns (high tone and low tone) with a mounting bracket for fixing screw M8.
