Hey, I did that too. You have to take the front bumper off. This will allow you to get the whole stock headlight assembly out, then it's all in putting it back togather the right way. If the lights you baught come with halo's or clips to plug into your stock harness, be sure to not wrap the harness in any places it will be pinched by the corner lenses, this will be a real pain in the ass to fix because you have to take the whole bumper off again. and if you have lowered your car, I'd defanitly jack both sides up to fit under better, trust me, I didn't do that it was much more of a pain the in ass! anyway, if you have anymore questions, E-mail me at Badling22@aol.com
