How to replace radio/clock lights

To fix this you will need to pull the radio out of the car and take it apart to expose the bulbs and replace them. Before you do this though, does the radio provide sound and, other than the lights, appear to function correctly? If not, then I would first check its fuse and, possibly, a second fuse on the back of the unit. If they are good and you get sound through the radio, the proceed with changing the bulbs.
