Why are my Audi A5 headlights flickering?

I've noticed that my Audi A5 headlights have started to flicker while I'm driving at night. It's not constant, but it happens often enough to be a concern. What could be causing this and how can I fix it?

There could be a few potential causes for your flickering headlights. One possibility is that there is a problem with the electrical wiring or connections. Another possibility is that the bulbs themselves are starting to malfunction. It's also possible that there is an issue with your car's voltage regulator. I would recommend taking your Audi A5 to a certified mechanic to have it checked out and repaired as soon as possible.
