pretty easy. i think the hardest part was trying to find a good location for the lights to be considering getting at the front fenders wasnt easy and covered with stuff from inside the engine bay.one issue i had was getting a different color or no color from each pod but that was my fault not realizing the plugs had arrows that needed to match. oops. i also only have 6 installed right now, undecided where to put the other two. love the product. i would defenitly buy it again
