Do it yourself...
The 'indiglo' lights up white...
The overlay is painted green on the backside.
It's layered over the silver and the digits, so removing it would remove everything.
Scan the overlay, Photoshop the silver out of it, print it on quality white paper and you have your new overlay...and it'll be WHITE.
I did this, and added a blue film underneath and made this...
(Also white and a transparency over the white)
And in the daylight...
(If you look closely, I also Photoshopped out the MPH, enlarged the SVT logo, and thickened the redline)
I don't have any pic's of the current white output though.
More images...
(here is what happens when you try to remove the green from behind!)
