Review on 🚗 CARMOCAR Electric Car Horn Kit 12V - 135db Super Loud High Tone and Low Tone Metal Twin Horn Kit | Ideal for Cars, Trucks, SUVs, RVs, Vans, Motorcycles, Off Road & Boats (Green) by Larry Gaines

Used to replace regular horns. While not designed for trucks, it's a little louder than the original, but spend the time and money installing truck horns. These horns do not require a special +- terminal assignment! With this type of horn you do not need a separate suspension when replacing the standard horn(s)! Simply ground one of each horn and the other horn pin connects to the vehicle's serial wiring. A separate harness should really only be used when attaching antlers.
