Truck Horns

Loud air horns for trucks, buses and heavy duty vehicles, from 4 and 6 trumpet musical horns to train-style whistles and two-pipe pressure horns. Most work on both 12V and 24V.

How to choose a truck air horn

• Sound: musical horns like the ROMEO and Road Master series play up to 20 melodies. Whistle and pressure horns give one strong, classic blast.
• Air supply: most truck air horns run from your vehicle's onboard air compressor. Smaller vehicles need an external compressor.
• Voltage: check whether your truck runs on 12V or 24V. Every product page shows which voltage the horn supports.

Road-use restrictions and responsible sound use

Before buying or fitting a horn, check the rules for your country, vehicle class and intended use with the local road authority. Musical, multi-tone, train-style or high-output horns may be restricted. Compatibility with a vehicle does not establish road approval. In the UAE, official guidance restricts horn use within city limits to emergency situations. Do not use a horn to demand priority, clear traffic, celebrate, intimidate or startle people or animals. Follow noise restrictions and keep testing away from bystanders.

Safe installation and testing

Use a qualified vehicle electrician or air-system installer if unsure. Match the horn to the confirmed vehicle voltage and follow the supplied horn and vehicle instructions. Isolate electrical power as directed by the vehicle manufacturer before wiring. Use the specified fuse, relay and cable size; do not guess ratings. Secure the mounting and route wiring and air lines away from heat and moving parts. For air horns, confirm the required pressure and fittings, depressurize before disconnecting lines, and do not modify safety-critical braking systems. Keep people clear of the horn outlet and use appropriate hearing protection during testing. Keep the vehicle’s required warning horn operational.
