Hi i have seen this done before. You need boxster clear headlights and then a gold film for the lights. This film also protects the lights from stones ect... you can get it in clear from some websites but they do a gold also, they look really good, about $15.00 per set.
cant remember the website now..
best thing it takes 2 mins to put on and can peel off when ever you want, its water proof and does not damage or effect the headlight apart from a gold light field at light
