What is the function of the Audi A8's matrix LED headlights?

I have heard about the matrix LED headlights in the Audi A8, but I'm not sure what exactly they do. Can you explain their function and if they are worth the extra cost?

The matrix LED headlights in the Audi A8 are a revolutionary technology that allows for more precise and dynamic lighting on the road. They use multiple LED elements to selectively dim sections of the headlights, allowing for optimal lighting without blinding other drivers. They are definitely worth the extra cost, as they provide improved visibility and safety while driving.

The matrix LED headlights in the Audi A8 are an advanced feature that allows for adaptive lighting while driving. They can detect oncoming traffic and dim specific sections of the headlights to prevent glare, while still providing adequate lighting for the road ahead. I highly recommend opting for this feature, as it adds an extra level of convenience and safety while driving at night.
