This is a premium horn kit that produces a luxurious, deep tone by simultaneously sounding two tones of different frequencies. It's called the "Lexus Horn" because it achieves a tone equivalent to the horn of the luxury car brand Lexus. It's a very popular customization item because you can easily modify your car to Lexus specifications. Being a general-purpose product, it fits many car models if the size is appropriate. It can be installed on 12V vehicles, including Toyota Hiace, Noah, and Voxy, as well as large vehicles from Honda and Suzuki, down to 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 had a high-pitched horn, will instantly sound like a luxury car. ◆ Easy Installation For Toyota vehicles, which are the same as Lexus, it can be a simple plug-and-play connection to the coupler, or it can be connected to the existing 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. ◆ General Purpose It can be installed on 12V vehicles if the size is appropriate. Please check the size and install it properly so that it does not interfere with other parts, including Honda, Nissan, Mitsubishi, Mazda, and Subaru. ◆ Waterproof Made of ABS, it can withstand wind and rain while driving. When installing, please install it to 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 brackets included ★ Shipping ★ Shipped via Yu-Packet Plus, expected to arrive in 2-5 days.
