If you want the LED's, look on ebay, they have the kits on there to swap you over. As for the painting, they have interior spray for plastic parts. Should be able to find at any auto parts store. Me, I just used a good spray paint, krylon I think,and it has worked fine. Just have to prep your parts good and use some good primer first. If you use any type of protectant on the parts you want to paint, clean them good with some paint thinner or acetone, which might work better. If you don't clean good, your paint will bubble and flake off. Once you get your parts clean, don't touch any areas that you are going to paint because the oil from your hands will cause the same reaction. Unless you know how to replace a headliner, I'd take it to a shop.
