Reliable Quality: Carefully crafted from high-quality ABS, this car air horn offers excellent hardness and wear resistance, ensuring long-term durability and reliable performance. Its thickened horn mouth enhances impact resistance, maintaining structural stability

Practical Function: You can make a sound of 105-115 dB through the air horn to warn or remind pedestrians or vehicles around to give way during driving. When encountering complex weather, this horn enables you to communicate non-verbally with others, thereby enhancing driving safety

Operating Principle: When the button is pressed, the current from the battery flows to the electromagnetic coil of the relay. After the moving contact switch of the relay closes, the current flows to the horn. The current makes the electromagnet work, thereby causing the membrane to vibrate and produce sound

Easy to Install: First, close the car's power supply. Next, connect the positive and negative terminals of the power supply to the horn, respectively, with the red power cord and the blue ground wire. During the installation, its opening should be tilted downward at a 45° angle to keep rain from entering
