Review on 🚗 SYOAUTO 12V Waterproof Compact Car Horn Truck Horn - Universal Fit High Low Tone Electric Snail Horn Kit for Super Loud Replacement Car Horns by Andrew Webster

I thought about the idea of putting a horn on the back of my car because a few times I wanted to honk the driver behind me but I didn't. not because the driver in front of me would wonder why I'm signaling them if I'm not. I tested this beep with a 12 volt power supply and it was loud. I installed it under the rear bumper where it's not visible. I will use an extra button on the dash to sound the horn and use a fuse to turn the horn on. I'll post an update when I'm done installing and confirming everything is working fine. update finished! That works great. I like the balance of high and low frequencies. As you can see in the picture, I installed the button on the dashboard. The horn itself is completely invisible as it is completely hidden under the bumper. My Accord now has a secret weapon for truckers!
