What Is This Tour de France Horn?
The Role of a Horn on a Commercial Vehicle
A horn is a mandatory safety component on every vehicle used on UK and EU roads. It provides an audible warning in hazardous situations. According to UK Government vehicle regulations, horns must produce a continuous, uniform sound and are tested during annual inspections.
What This Pneumatic Horn Includes
This horn uses pneumatic operation rather than a standard electromagnetic diaphragm. Compressed air passes through three separate trumpets, each tuned to a different frequency. The result is a rich, multi-tonal sound that carries further than single-tone horns.
For technical information on vehicle audible warning devices, refer to Bosch automotive electrical systems.

When to Replace Your Horn
Signs of Failure
Watch for these indicators:
No sound – Press the button and nothing happens. Check the fuse and relay first. If power is present but the horn is silent, replacement is needed.
Weak or distorted sound – Reduced volume or raspy, uneven tone indicates internal failure. A new unit restores full 117dB output.
Single tone only – Only low, only middle, or only high tone produces. One trumpet has failed. A working unit delivers all three tones.
Legal Requirements
All motor vehicles on UK and EU roads must carry a functioning horn. According to UK Construction and Use Regulations, horns must not produce a harsh or discordant sound. The three-tone output of this horn meets these requirements.
Annual testing includes mandatory horn inspection. HELLA vehicle horn guidelines confirm pneumatic horns are permitted on commercial vehicles. This unit meets all applicable standards.
Why Choose The CARPOINT 0524731 Tour de France horn
117dB Output
At 117 decibels, this horn is significantly louder than standard units (95-105dB). For vehicles operating in high-noise environments, the additional volume ensures the warning is heard.
Three-Tone Pneumatic Operation
Compressed air passes through three separately tuned trumpets. The low, middle, and high tones blend to create a rich, multi-frequency signal that cuts through ambient noise effectively.
Tour de France Heritage
The Tour de France product line takes its name from the cycling race’s traditional caravan vehicles, which used distinctive multi-tone horns. This unit brings that classic sound to modern vehicles.
Direct Fastening
The horn mounts directly to the chassis or existing bracket. No complex adaptor systems or custom fabrication required.
Installation of CARPOINT 0524731 Tour de France horn
This horn requires basic electrical and mechanical knowledge. Direct fastening means the unit bolts directly to a suitable location. Connect the wiring to the existing horn circuit, observing correct polarity. For vehicles with only one horn wire, ground the second terminal to the chassis.
The horn includes an integrated pneumatic compressor. No external air supply is needed. Ensure the compressor intake is not obstructed after installation.
Always test after installation. Press the horn button and confirm full 117dB three-tone output.
For installation guidance, consult Mercedes-Benz truck service documentation.
