Turns out both low beams burned out at the same time. Both were bad. Never seen that happen before. I would assume a surge or ground issue, but if that were the case the fuse should have popped too, right?

Not sure what to make of that. I do see the dome light sometimes flickers at idle, they aren't LEDs, maybe an issue with the voltage regulator? unsure if thats even related. The previous owner definitely cut some corners on wiring that I've been fixing this week.
