Squadron 2.0 On/Off 1-Light Harness w/ Backlight | Baja Designs

Wiring a single Squadron 2.0 light straight to the battery without a relay or switch is a recipe for a blown fuse or a light you can not turn off. This 4-pin Deutsch relay harness powers one Squadron 2.0 light directly from the battery, with an included three-position toggle switch and backlight support, and it can be expanded with splitters to run more lights.
