Review on FARBIN Car Horns 12V Loud Dual-Tone Electric Auto Horn Train Horns Kit For Trucks Motorcycle (Green Horn by Brad Blake

For plastic: They're durable. Got these for my 2021 Softail standard as a replacement for the Whimpey Stock Horn. I realized that in order to turn on both horns I would have to get a relay and run a line with a fuse. So I decided to just use one of these, I went with 510Hz and it fits perfectly into the default layout so it's not visually flashy but it will make you jump when it turns off.
