Interior lighting, LEDs Options

[UVZ164]

Hi guys,

I've done alot of reading on LED lighting and just have a few questions before I order everything.

My shopping list is as follows:

3x Blue 194 led for gauge cluster
2x White 194 led for door courtesy lights
1x blue led for window switch
1x blue led for ash tray

Now the climate control is where I get confused. My understanding is that I need:

1x led for each button on the CC
3x 10mm neo wedge led for backlighting
1x 8mm neo wedge led for rear defogger backlighting

Now the two questions:

1. Will the 3x Blue 194 led for the gauge cluster be enough to fully light it up as well as the needles?
2. Is my list correct for the climate control?

Thanks in advance!
