Audi S7 2018 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2018 Audi S7 by lighting position, so you can match the correct replacement before you buy. Because the S7 uses a mix of LED lighting and a few smaller interior bulbs, checking the exact location matters more than guessing by appearance alone.
Use the bulb chart on this page to confirm the fit for exterior and interior lights such as the headlight high beam and low beam, brake lights, turn signals, license plate lights, and cabin lamps. That makes it easier to compare the bulb type in your car with the listed size for the 2018 Audi S7.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm the installed bulb before ordering replacements. Many positions on the 2018 Audi S7 are LED from the factory, while a few interior and marker locations use smaller incandescent-style bulbs such as 2825 or 98. If you are considering an aftermarket LED conversion, make sure the bulb matches the socket, polarity, and any required load or error-canceling needs. The safest approach is to inspect the existing bulb or compare the part number and connector style before purchase, especially for lights that may differ between regions or optional packages.
