I have seen many threads from America and Europe detailing how to do this, ie cook them in the oven, and use a heat gun, however i have tried both of these methods and none seem to work... I bought a pair of second hand headlights (thanks DUB20V ) to use the reflective piece, as i want to spray it black, so i dont mind if these units get butchered (sorry DUB20V ) but id rather not butcher my units while trying to put the new black reflective piece into my headlights...

has anyone attempted this with any luck? or am i just going to hear that im butchering a pair of headlights for fun

Cheers Evan.
