05_LLY· Hi, I'm Earth. Have we met?
It has been a few years but i have taken a radio apart and replaced some lights in it but it was not any fun at all. i dont think they are meant to be able to be changed but if you can find the bulbs andhave lots of patience and little tools you can do it! AS for the heater controls i have never tried but they look like a sealed unit to me?
