I know this have been discussed several times before, I have searched but some of the threads are way back from 2007 and I thought that maybe there's been some development since then.

I've just bought these plasma dials:

I've read that I'd might have trouble seeing the needle at the night and that it should be illuminated. What would be the cheapest and easiest way to have this done?

Also, would I be able to cut with scissors in the plasma dial with out ruining it?

The reason I'm asking is that I want to cut out the bottom part so that it will fit the black part of the background of my original dials. I thing have six black dots in the bottom of the rev dail looks kinda ugly.

Thanks in advance.

I'm also wondering what it would look like if I kept the blue leds I have fitted now and put the plasma dials over it? Maybe then I would be able to see the needles more clearly?
