i know this is semi all over the internet, but ive never retro fitted a headlight but i really want to do it. it seems semi easy but then again alot can go wrong. should i retrofit or just buy some projectors? i mean the retrofit looks so dope on our cars especially by lightwerkz but i cant justify shipping my headlights and paying 450$ to get them done. just know there are 20 things i can think of off the top of my head that are better to spend 450 on. suggestions?
