Virtual LED help?

Hello

I’m new to this so please be kind lol. I have recently got into sim racing and stumbled upon Simhub, I’ve been playing around with it and made my own virtual dash but I am now stuck with the LED side of things.

Basically I have a small area left where I wanted to put 4 LEDs (virtual ones like in the Rev counters) for the white,black,blue and yellow flags. How do I do this and how do I also have a blank (off) led in its place for when there’s no flag?

Could someone help please?

Thanks in advance
