That is good you have found the actual bulb. I have had very good luck with replacing them with a bulb from Radio Shack. They sell some small glass bulbs with long wires that are normally used for radio backlights.

I have just taken the old bulbs out of the small black plastic holder and then rewrapped the new bulb wires in the same way and cut off the excess. You can tell a difference using them in the instrument panel, but you can't tell a difference using them in the Homelink buttons.
