output meter level to pad (led feedback)

I have made this script to test if i could send the output meter level of a specific track (L1) to the led feedback of pad 1 of my Launchpad Mini. It works but the pad lights up red when there’s audio playing and nothing when there is no audio playing.
Ideally I would like to use the 3 colors (amber, green and red) to give a sense of the track volume so that when the output meter level changes the colors can follow this.
I have set the led feedback color reference in my controller template like this:
off = midi velocity 0
amber full = midi velocity 25
green full = midi velocity 50
red full = midi velocity 75
That way I would have 4 levels of led feedback for the output level meters:
no level: pad is off
low level: pad is amber
medium level: pad is green
high level: pad is red
So when the audio is playing the pad should alternate between these 4 levels as the output meter level changes over time
How can I adapt my script to get this working?
