These horns are just what my automotive needed! Based on my observations, the Vixen Horns Dual Tone Horns are impressively loud, with a dual-tone feature that makes for a distinct and striking sound on the road. I love that they are easy to install and come with a wiring kit, making it a breeze to get them up and running. However, they may not be suitable for motorcycles due to their larger size. Overall, I highly recommend these horns for anyone looking to upgrade their car's horn system.
