Wide Compatibility with Vehicles:
Mainstream Passenger Cars: The first choice for direct upgrades of 12V system models such as sedans, SUVs, and MPVs.
Commercial & Special Vehicles: Suitable for 24V system vehicles like trucks, buses, and construction machinery (utilizing its wide voltage auto-sensing capability).
New Energy Vehicles: Has passed electromagnetic compatibility (EMC) testing and does not interfere with sensitive vehicle circuits.
Professional Installation Guide (3 Simple Steps):
Locate: Prioritize the original horn location. If adding a new one, choose a well-ventilated area behind the front crash beam.
Orient: Adjust the horn's sound outlet to face directly forward in the vehicle's direction of travel, with a downward tilt of approximately 15° to ensure optimal ground reflection and sound propagation.
Connect: Use the original vehicle wiring or the provided harness. After connection, ensure all fixtures are secure. The standard φ82mm mounting aperture is compatible with the mounting points in the vast majority of vehicle models.
