yes the light can be replaced. There are three small bulbs on the back of the DIC (inside the black plastic case) ... Here is how I got my DIC apart to replace the bulbs.. You'll have to remove the face of the dic by gently using a real small thin blade screw driver to press the clips in a little bit,(kind of working your way around the dic) once you pop the face off it you'll see a couple tiny screws that hold the DIC/circuit board inside of the black plastic housing. They are a torx bit screw but since I didn't have my torx bits handy I was able to use a precision screw driver(straight tip) that was tiny enough to fit inside the screw head. Just unscrew them and set them aside. Next you'll have to un-clip the circuit board from the black housing. Once you do that it should slide out easily. There are three bulbs on the back of the circuit board. ( I believe they are # 74 bulbs, someone correct me if I'm wrong) They will just twist out of there, then you can replace them with new ones. Then you basically put everything back together the way it came apart.
