The 1999 Audi A6 Avant uses a dual bulb headlight system. This means you have separate bulbs for high and low beams.

Rules for LED headlight retrofits vary by location and by housing type. Avoid products that create glare or lack road-use compliance claims, and check local requirements before using an LED conversion on public roads.

Halogen bulbs and LED replacements differ in output, heat behavior, beam pattern, and electronics. A correct bulb code does not guarantee a correct LED beam pattern, so verify physical fit and seller compatibility notes for the 1999 Audi A6 Avant.
