Review on LAMPHUS SoundAlert Police Air Horn Kit 12V 100W [Slim Speaker] [118-124dB] [Hands-Free] Train Truck Siren for Vehicles Truck UTV ATV Car POV by Kevin Hutchison

Very simple setup, very loud and fun. I got tired of replacing that $30 air horn I had under the hood every year so I jumped out because of that, couldn't be happier. Fits perfectly behind the bars of my Jeep and delivers what I need and what, amazing and loud sound. UPDATE: I put this in my Wrangler, it's only used 6 months a year. This horn is already out of service. Using the instantaneous switch provided by the manufacturer, this gives a very brief "chirp" of less than a second.
