Try look up a DIY on Honda forums, its a very common mod for the Ek civic and the dc5 RSX as in america they come with chrome hosing. It's basically take your headlight apart and place it in a oven. Oven should be at 200degrees but when you put the headlight in turn off the heat so its just warm in there enough to melt the glue so you can pry it apart. It takes along time, but alot easier if you have a big oven. I did this too my celica and the s2000. The celica i got some help and was also in a Big oven so it was easier. The s2000 I did myself and the headlight didn't fit inside the oven so it took me around 8 horus to do both. Also have to wrap the headlight in a towl of some sort so it doesn't get burnt/melt. Once you take it apart you should be able to seperate everything and see which bit you have too paint. Get any matt black paint to paint it and seal it up the same way you open it in the oven. You could also add silicon to make sure there's no gaps because if there is the headlight will fog up on cold nights. Best too look up a DIY like on Clubrsx or hondatech its a very common mod, same with all cars and they have pictures. Good luck mate, oh and that isnt my sportivo its my mates kaze, I just took the photo.
