Hella Sharp Tone Yellows (H31000001)

Imagine this. You're sitting in your brand new 2015 Subaru WRX, intake and exhaust, mint condition. you're on your way home after a long day at work when out of nowhere, a big work truck comes blasting into your lane.

loud horns

I got these to replace a worn set on my wrx. Easy install and loud enough to get someone's attention real quick. Really couldn't beat the price either!

love them

these dual tone horns are just what i have been looking for. i like both the tone and that they are loud enough to get my point across.
