Toyota makes some great trucks but they still use the halogen bulbs in their taillights. Led tail lamps are so much more efficient and safer so Adjure Inc. made some to fit the Toyota 4 Runner, FJ Cruiser and the Tacoma. Led taillights run cooler, draw less current (go green), last longer (no more changing burt out bulbs), are much brighter (so they can be seen from farther away) and are instant on and off. For example if you are traveling at 60 mph and apply the brakes, the driver behind you will see your brake lights 120ft sooner then he would if they were halogen (stock) lights. Looks and safety in one great package.
