2017 Audi S6 Bulb Size

When I first looked up bulb sizes for my 2017 Audi S6, I wanted one clear place to check compatibility quickly. Think of this list as a simple reference that matches each lamp location to the correct bulb type and size, a mental model that saves time and reduces guesswork. A quick win is spotting the headlight, fog, and interior bulb types at a glance, which makes buying replacements feel straightforward. As you expand to brake, reverse, and signal lamps you’ll see a consistent rule of thumb: keep the vehicle year and model handy to avoid mismatches. From my experience this approach prevents returns and fussy fits. Quick recap: use the chart to identify bulbs, then verify fitment before purchase.
