Made of ABS polymer material, this horn offers strong corrosion resistance, is waterproof, and won't rust or short-circuit in the rain, extending its lifespan and making it easier to use. The internal reverberation design, reaching up to 300dB, provides a loud voice to warn others and enhances driving safety. Our snail horn can help reduce unnecessary injuries. There's no bulky air compressor required, just a small device that produces an amazing sound. It's so compact that almost half of our customers buy and install two horns to double the volume. The unique mounting bracket design ensures a more secure installation, and the universal bracket allows for installation in any position. It only requires a 12V power supply, reducing energy consumption. The horn is suitable for almost all vehicles. Although it's the perfect upgrade for trucks, our horn is also compatible with SUVs, cars, boats, and motorcycles.
