Customize the look of your vehicle and light up the night with HIDextra high intensity headlamps, and of course, you’ll want to bring along a HIDextra coupon code when you shop, found here at Goodshop. These replacement headlights are brighter, safer, and last three times longer than conventional headlights. Conversion is easy, a 45-minute DIY project. You can even pick the color you want: yellow, white, ice or deep sea blue. Shipping and returns are free and they include a one-year warranty.
