OIRAN BIG HORN

A single note, carried the length of the road.

The OIRAN BIG HORN is a large-format air horn developed in collaboration with Grover Products, the air-horn specialist — Grover’s horn-making joined to OIRAN JAPAN’s standards for Japanese heavy-duty trucks. Stated output of approximately 120 dB.

• Air-operated: connects to the truck’s on-board compressed-air system.
• Stated output of approximately 120 dB.
• Collaboration model with Grover Products.
• Mounting and fitting guidance before ordering — contact us with your truck’s details.

This is truck hardware, not an accent piece: a horn is heard before the truck is seen, and it is chosen the way any working part is chosen — for what it does, every day.

Audible warning devices are regulated equipment. EU / EEA: verify local regulations before road use.
