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. Being a general-purpose product, it is compatible with many car models if the size is suitable. It can be installed in 12V vehicles, including Toyota Hiace, Noah, and Voxy, as well as large vehicles from Honda and Suzuki, and even kei cars and motorcycles. ◆ Tone By simultaneously sounding two types of horns, 510Hz and 410Hz, you can achieve 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 For Toyota vehicles (like Lexus), it can be a simple plug-and-play installation with the existing coupler or connected to the original bracket. For other manufacturers where the coupler or bracket is different, customization is possible with some modification. If the fuse blows, use a relay. If the original horn 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 It can be installed in 12V vehicles if the size is suitable. Please check the size and install it properly, ensuring it does not interfere with other parts, for Honda, Nissan, Mitsubishi, Mazda, Subaru, etc. ◆ Waterproof Made of ABS, it can withstand wind and rain while driving. When installing, avoid water ingress from the horn part. * 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 brackets included ★ Shipping ★ Shipped via Yu-Packet Plus, expected to arrive in 2-5 days.
