Help: Custom Light indicators and switchet gauge faces

Hello guys,
I´m currently working on a dash for my AE86 running a Storm G4x stand alone ECU and running RealDash on an Atoto X10 2Din

I´ve always loved the 1Din Defi gauges set, and im always missing my laptop to be able to see how everything is working.

I have a RPM Limit depending on Oil and Coolant Temps, etc, so I wanted to see how is it going.

QUESTION 1:
Id like to ask you guys if anyone knows how to config custom PNGs as light indicators, as i have been spending the last weeks trying to figure it out but seems to be impossible.

I have set 3 light indicators to show the Fan 1, Fan 2 and Fan 3 state (On/Off), but would like it to be like this:

QUESTION 2:
The Defi gauges are white, but would like to know if it would be possible to sitch the gauge face to red if the car lights are on (radio dims down automatically when this happen) or if the value, say Coolant temp, rises above a number

Thanks in advance!

Every gauge as 3 operating levels, Normal, Warning and Critical. Pretty much all parameters of the gauge can be set separately for each operating level, including colors, texts etc.
