This is a premium horn kit that produces a luxurious, deep tone by simultaneously sounding two tones of different frequencies. It is called the "Lexus Horn" because it achieves a tone equivalent to the horns used in the luxury car brand Lexus. It is a very popular custom item because you can easily change your car's horn to Lexus specifications. Since it is a general-purpose product, it can be used on many car models if the size is suitable. It can be installed on 12V vehicles, including Toyota Hiace, Noah, and Voxy, as well as Honda, Suzuki, and other large vehicles, from light cars to motorcycles. ◆ Tone By simultaneously sounding two types of horns, 510Hz and 410Hz, it achieves the deep resonance of a luxury car. Your car, which used to have a high-pitched horn, will instantly sound like a luxury car. ◆ Easy Installation If it's a Toyota vehicle like Lexus, you can simply plug it into the coupler or connect it to the original stay. For other manufacturers where the coupler or stay is different, customization is possible with some modification. If the fuse blows, use a relay. If the original is a single horn, you can make it a double horn by attaching double horn wiring. * Please prepare the wiring separately. * Please consult a specialist for installation methods. ◆ Universal Use It can be installed on 12V vehicles if the size is suitable. Please check the size and install it properly so that it does not interfere with other parts, such as Honda, Nissan, Mitsubishi, Mazda, and Subaru. ◆ Waterproof Made of ABS, it can withstand wind and rain while driving. When installing, please avoid water ingress from the horn part. * It is not completely waterproof. ★ Specifications ★ Lexus-style sound horn 12V vehicle only Hi/Lo 2-piece set Hi-510Hz Low-410Hz 110db±3 Black 2 mounting stays included ★ Shipping ★ Shipped by Yu-Packet Plus, expected to arrive in 2-5 days.
