SoundOff was the first to work with Chevrolet and Ford to develop Plug-in Flasher systems exclusively designed for specific Police Package vehicles created for the law enforcement community. These vehicles have built-in wiring that our flashers simply and easily plug into which will almost eliminate installation time and insure wiring integrity.

Did you know SoundOff Signal invented the very first high conspicuity - extreme use wig wag headlight flasher over 25 years ago? When you purchase a genuine SoundOff Signal flasher you can be assured that you are buying from the leading flasher manufacturer. Our expertise, unmatched technical support and No Hassle Warranties are why we are the trusted leader in flasher systems. It’s a fact, we manufacture & sell more flasher systems than all of our competition combined. It begs the question, Why would you buy a flasher from anyone else?
