Description

The Hadley H00978 ECE Truck Horn is a high-tone, rectangular air horn designed for trucks and other vehicles with an onboard air supply. It features a steel projector with a chrome finish and is known for its full and clear sound. It is recommended to combine it with the low-tone H00977 ECE horn for a complete set. An air source with a valve/solenoid and tubing that produces 4-8 bar pressure is required for operation.
