The conversion showed above was done completely with white and blue LED's.
Bulbs are no longer used.
The gauges display was completely replaced by a plasma display which is self-iluminating.
The LCD display of the odo was inverted by changing the polarisation of the foil.
The bulbs of the centre console were replaced by white and blue LED's.
It's a little bit difficult to replace the LED's in the switches.
There was a circuit added that allows to dim all LED's and the plasma display simultaniously.

So this wasn't done by just changing bulbs.
