Basically i can still get some free Xenons off a 182. i noticed the other day that a plastic bit on the inside of one of my headlights is also smashed. so i want to do a swap with my mate. i posted earlier as i thought it was just the unit itself but i was made aware that there is more 2 it. so im wondering if anyone can give me an insight or guide as to what i need to do to swap them and where to start. also do you need to take the bumper off to get the headlight unit itself out?
