Dash Light Replacement

The light on the rear defogger switch has finally gone out. Is there a replacement for this or is a "Make One" situation?? I know the headlight one was a BYTCH to get and had to be made up from parts from Radio Shack.Thanks in advance. This is a 97 explorer sport OOPS me bad 8^) Went to the JY and got a handfull of the bulbs. PROBLEM SOLVED !!!!!!!!!!!!
