X350 headlights

Morning all. Happy new year!

Tiny problem today. My dipped beams have stopped working. Both of them, at the same time. Wont come on in either manual or auto modes. Unless I have had simultaneous bulb and fuse failures ( unlikely) for both sides what should I be checking? Side lights and full beams still functioning. No warning lights or messages. Car has normal bulbs, not xenons.

Update. Both bulbs blown. Never had a double simultaneous bulb failure before. Hope its not an indicator of something more serious

Strange to have both go. A rough guess would be that one failed in such a way to cause a surge of some kind that didn't cause a fuse to blow, but took out the othe bulb. But, having said that, they are usually on different fuses.

Yes, they are on separate fuses. Most strange. New bulbs are in and seem to have no issues so far.
