2004 Boxster instrument panel lights?

[N227RV]

The light behind the speedo display is dim in my 2004 Boxster SE, so I will pull the instrument cluster to change what may be a non-functional bulb. While I am in there I should replace all the other easily replaced bulbs. Here is my shopping list. Am I wrong about any of these? ...

12v 3w: 999-631-304-90 / analog gauges (4 needed)
12v 1.5w: 999-631-303-90 / digital display (3 needed)
12v 1.2w: 999-631-302-90 / idiot lights (unknown if these can even be replaced)

As you can see, I need to know how many 1.2W bulbs I'm going to need for the idiot lights. Or let me know that these cannot be easily replaced and I will be content to leave them alone since they all seem to be working just fine.

I think the 9x6.2 instument clusters are backlit with leds instead of bulbs.
I can't find any pictures but maybe the displays are backlit with multiple leds and one of them isn't working?

I pulled the dash on my 2003 base apart to replace the lights, only to find there are no bulbs. The fix requires changing the headlight switch instead, which was much easier than taking the instrument cluster section of the dash apart.

I haven't removed the instrument panel yet, but thinking about it ... the problem may not be a bulb. What I have is a situation where the lighted panel in the center, which displays various sorts of information under the tachometer, is dim when I am driving with the lights off. It is definitely more dim than the other panels to the left and right. It comes to full brightness when I turn the lights on. I assumed that was backlit by a conventional bulb, but maybe it is a LCD panel instead?
