150DB Train Horns Kit: Our train horn kit delivers a robust 150dB sound with strong penetration. Ideal for long-distance driving, sharp turns, and adverse weather conditions. It effectively alerts cars, pedestrians, and animals. The electric train horn kit includes 4 trumpet air horns, a solenoid valve, a 1.6-gallon tank, a compressor, and pipes. (Note: Power switch and cord not included.) 90-120 psi Air Compressor: The compressor operates within a 90-120 psi range, with a sensitive gauge for real-time pressure monitoring. It automatically inflates at below 90 psi and stops at over 120 psi to prevent overpressure. The tank maintains optimal air pressure, enhanced with fuses for compressor protection and a drainage plug for easy water release. Strong Air Tightness: The train horn kit for trucks is made from heavy-duty zinc alloy and steel with anti-rust coating. The truck train air horn kit is corrosion-resistant, impact-resistant, and wear-resistant. The air compressor features a non-leakage structure and a tightly welded air tank to minimize leakage risks. Shock Absorption and High-Temperature Resistance: The 4 trumpet train horn kit includes a thick rubber cushion for noise reduction and enhanced stability when installed between the tank and vehicle bottom. The PA gas pipe withstands temperatures up to 120℃, and the motor is equipped with a 100℃ temperature control overload protection, ensuring safe operation in various weather and road conditions. Universal 12V Compatibility: Our train horn kit is designed for any vehicle with a 12V battery system, making it suitable for trucks, SUVs, cruise ships, and more. Its universal compatibility ensures ease of use without concerns about incompatibility. › See more product details
