SoundOff Signal Isolation / Negative Switched Headlight Flasher

It was over 25 year ago that Sound Off Signal pioneered the headlight flasher industry when they created the first widely used device to utilize your own vehicles headlights as an emergency warning device. No one else had thought of that before. The flashers are such high quality, that Sound Off sells more headlight flashers than all of our competitors COMBINED! Now 25 years later they still lead the industry not only in headlight flashers but emergency vehicle warning equipment as well. Headlight flasher includes isolation technology. It's great for use with Dodge vehicles as many of them are a negatively switched wiring system. Check compatibility BEFORE ordering - Click here!
