Bulb for DIC main screen is Sylvania #24. You need three bulbs for the main screen. Just replaced all three on mine a few weeks ago. Got the bulbs at Pepboys.

Once you remove the old bulbs+blue mounts (they just kinda twist off, bulbs and mounts are one piece), you gotta break the old bulbs free from the mounts and remove them and put the new bulbs in the mounts.
