Review on Hella Stark Sound - Red Set 12V H/L Frequency Hella Super Tone Horn Set B 133, 12 volt by Eric Avina

The existing horn in my 2013 Nissan LEAF was dingy to say the least. I think half the time he wasn't noticed on the street. Well, not anymore! Realizing how easy it was to replace the horn, I found this kit. I decided to use the existing wiring at about 18 gauge, so I decided to just use one horn from the kit (at 300Hz) as I was concerned that the 18 gauge wiring wouldn't be able to handle the current for both horns would. Measured with my Apple Watch right in front of the car, the previous horn was 92dB and the new one registered 101-102dB, meaning their intensity has increased by 10x. It's loud enough now.
