Default HVAC Control lights brightening and dimming while headlights are on

So this started to happen after I had my alternator replaced. The green light on the HVAC controls has started dimming then brightening over and over while I’m driving with my headlights on. Normally I don’t notice it but it’s really annoying when I’m driving at night. It’s rhythmic so it’s not really acting like a lose wire. Any thoughts?

Sound like an issue with the alternator. Sometimes new aftermarket alternators are known to be faulty.
