Hi guys! Long time reader first time posting.
I have a 2004 Volvo s80 T6 with 94k miles and randomly while driving at low speeds my radio and headlights will turn off and right back on again. The last few days while driving to work (6 mile commute) it happened about 3 times each way but only seems to do it if my headlights are on. Did a ODB check and nothing shows up.

Anyone have any answers or dealt with this before?

 

I suspect the ignition switch. Spring is weakening, perhaps, especially if a lot of keys or other stuff on key ring in the 94K lifespan. Climated control lights probably blink off too.
About a $50 switch, takes a #15 skinny torzbit screwdriver and about 10-15 minutes to replace.
