SoundOff Signal's Universal UnderCover LED Insert offers innovative customization of light output with flexible mounting options. This LED includes three interchangeable lenses that tailor the light output to complement any mounting application. Insert is a quick and easy retrofit, fitting into existing 1" strobe tube cutouts in headlights, taillights or corner light assemblies. Insert is self-contained with in-line flasher and features a fourth wire to set optional 'cruise mode,' which reduces light output to 20 percent power. The new Surface Mount Bezels offer flexible mounting options, available in black, chrome and white. Comes with a five-year, no hassle warranty.
