Reply to Adding FADER VU METER on vci arcade using old buttons led.

I was believeing, that could be nice to add to my vci arcade some vu meter using the spare leds from the old buttons.
if i remember well, its like 8 green and 8 orange
so i was believeing of drill near the faders, and put 4 green, 2 orange and 2 red(orange led + marker) each side.
What are the normal volume value for a vu meter?
i was believeing of map like this:

red 100%
red 95%
orange 90%
orange 82%
green 70%
green 55%
green 40%
green 20%

Has someone tried do this?
