EVO Formance white LED Sidewinder Eye-Brows use extremely bright and flat LEDs that are mounted to the side of two flexible 50 cm (about 19.5 inches) black strips. The sideways facing LEDs provide the ultimate in performance lighting, giving onlookers the best possible view of your LEDs. When applied to a vehicle headlight, they work as daytime running lights. Because of their small size and high brightness, they can be installed in a wide variety of lighting applications. Useful for tricking out your truck, car, big rig, R/C toys, and yes even your boat – remember these are 100% waterproof. These lights will also enhance the safety features on your vehicle by adding additional visibility and awareness. A 12 volt power source with a 3 amp in-line fuse is required (not included). No ballast is necessary. The Sidewinder features high quality authentic 3M adhesive backing strips for quick and easy mounting. It also features a printed grid for cutting the Eye-Brows down to the perfect length for your application. Each Eye-Brow comes with 147 cm (4 foot 10 inches) of wiring. Don’t change… Evolve
