How to fix dim headlights on an Audi A2?

I recently noticed that the headlights on my Audi A2 are not as bright as they used to be. How can I improve their brightness?

Clean the headlight lenses with a specialized cleaner and microfiber cloth. Also, check and replace any dim or burnt-out bulbs.

Consider upgrading to brighter and more efficient LED bulbs. They provide better visibility and have a longer lifespan.

If the issue persists, it could be a problem with the wiring or the headlight switch. Take your car to a trusted mechanic for a proper diagnosis and repair.
