Offset Values LED´s Audio Panel

Hi,

hopefully this is the right place for my question. It´s my first thread here.
I am a cockpit builder on basis of the PMDG 737 NGX. So far I have realised many parts like
Mip, sixpacks, fire panel (main and cargo), some gauges and others
with mobiflight software. Currently I realise the Audiopanel and do not have the offset values
for the LED´s that are built into the
little buttons VHF1, VHF2, ADF1, ADF2, MKR and so on. Are these offset values available somewhere?

Any help is welcome.

Best regards
Michael
