Light Bulbs-es300 '97-radio & Trunk Replacement

[total1]

'97 ES300

I have a truck light bulb that is toast and I need to replace it. It's the Koita 12v 3W bulb that most auto parts stores state I should use the 194 or 194LL but that's not even close.

1) Where can I find the replacement bulb for the trunk? It looks like a fuse but it's a bulb?

Some of my radio lights are out. I can take the radio out via the snap-in portions above the radio and below the AC area and then remove the bolts retaining the radio to the vehicle and then the bolts retaining the radio and AC unit in their respective housing.

2) My question is: How can I replace the light bulbs in the radio? Such as the light bulbs behind the '1' and '2', the knobs, the "AM" and "FM", the up/down signal searches etc.?

Thanks!
