In the Cessna there are three lights that sometimes illuminate when your nav radio is tuned to a VOR or ILS signal.
I’ve been googling around but can’t find an answer.
What do these lights mean?
If i didn’t understand your question wrong, those lights with beeps mean you are at the outer, middle or inner marker. Just giving you information where you’re during an approach.

Which aircraft? On some ILS approaches there are up to three marker beacons.
blue = outer marker
yellow = middle marker
white = inner marker
Look for references to Marker Beacon, Distance to end of a runway on the flight path. I suspect the aircraft is within 5 miles of a ILS. I am not a pilot, but I worked for a manufacturer of cockpit gear.
What do these markers mean? Like is “outer” always x distance from a runway?
Probably Instrument Landing Sequence (ILS) outer marker, inner marker and I can’t at this moment remember what the third is… if I’m correct part of the automatic landing system
Exactly, but the distances vary with each airport/approach. You have to check the approach chart.
Great, thanks.
These lights don’t function with a VOR at all?
No. They aren’t ‘connected’ to anything. If you have a marker beacon receiver you will get audible and visual identification when you are passing over them.
