Shifter Light not turning on!

Hi all,
I have a 2004 Toyota Corolla CE and at night when I am shifting to Drive, or Reverse, etc. there is no light to let me see where I am shifting. I turn on the interior light in order to see it. Does anyone know what kind of fuse that needs replacing?. If you guys can just give me the name then I can order it... this has been a problem for awhile now. Thanks in advance if anyone can help.
Your gear shift light may not be functioning because the console shift indicator bulbs have burned out or there may be a loose connection. As a result, even though the gear shifter is still functional, the indicator lights won't illuminate. When you are driving at night, this could be a problem.
