Q & A

What's in the Box

Classic "Ah-oo-gah" horn sound powered by a heavy duty motor. Commonly called the ooga horn. This oogah horn provides 112 decibels and is easy to install. 12 Volt.


Relay Kit: An ah-oo-gah horn uses as much electricity as some starters. A new horn with a "grinding" or "sick cow" sound is a sure sign it isn't receiving enough amps. Cure this and prevent an overheated circuit with relay 910-64044 and prewired plug kit 913-64381. This kit is highly recommended for safety reasons and best tone.
