A little update for you, been in the man shed tinkering this evening
I first tried the new film on my spare cluster which still has the indigo backlighting and it looks like this...

Bear in mind this is a daytime pic with a bit of shading so the numbers actually showed up on my camera. Not sure what it will look like in the car but I'll get a pic when I try it
Now I had a bit of confidence I started with my Bora cluster that has had red/white LEDs fitted all round
This was the result...


Not entirely happy with the amount of bleed through the background has but tomorrow I'll be experimenting with a few filters to see if I can calm it down a bit. The camera does make it look brighter than it actually is though. One thing I have noticed is the white numbers on a black background don't look very easy to read when the lights are off but that could just be that it was dark. I have the VDO immo3 cluster anyway so I can have the displays come on with ignition if I want but it's something to keep in mind. More updates soon
