when i did it i just removed the bulb from the back and there was an orange covering on the bulb (just like the ones that light up the floorboards) its a very small white bulb that lights its up and i have yet to find anyone that sells them..if anyone runs across them let us know! I read somewhere that there is actually and orangish transparent paint on the back of the faces as well which would explain why mine are still a little orange but im not sure...
