How to fix dim headlights on my Audi A3?

I noticed that the headlights on my Audi A3 are not as bright as they used to be. What could be causing this and how can I fix it?

It could be a problem with the headlight bulbs or the wiring. I suggest checking and replacing the bulbs first and if that doesn't work, have a mechanic check the wiring.

Make sure to clean the headlights regularly and use quality bulbs. Dirty headlights and low-quality bulbs can also affect the brightness.

If the problem persists, it could be an issue with the car's electrical system. I recommend taking it to a certified Audi mechanic for a thorough inspection.
