This page covers the 2020 Audi S8 and helps you verify bulb sizes by lighting position before you buy replacements. Because the S8 uses a mix of LED exterior and interior lighting, the exact bulb type can depend on where the light is located on the car.
Use the bulb chart to match each light position on your vehicle, such as the headlight, brake light, license plate light, dome light, or glove box light. That makes it easier to confirm the correct fitment for routine replacement or a lighting upgrade.
Fitment can vary by trim, lighting package, market, and body style, so always compare the chart with the lights actually installed on your 2020 Audi S8. Many exterior positions on this model are LED, which often means the bulb is not serviced like a traditional halogen bulb and may require a complete module or assembly instead of a simple bulb swap. If you are considering aftermarket conversions, make sure the replacement is compatible with the vehicle’s electrical system and any warning-light monitoring. Before ordering, remove the original bulb or inspect the housing to confirm the installed part number and connector style, especially for interior positions such as the glove box or interior door lights where 2825/98 bulbs may be used.
FAQ
Does the 2020 Audi S8 use LED bulbs in most exterior positions?
Yes, the 2020 Audi S8 uses LED lighting for many exterior functions, including the headlights, brake lights, tail lights, daytime running lights, turn signals, license plate lights, and several marker and cornering lights.
Why does this page list bulb sizes by lighting position instead of one size for the whole car?
Different lighting positions on the 2020 Audi S8 can use different bulb types or LED modules. Listing them by position helps you verify the exact fitment for each lamp location instead of assuming one bulb works everywhere.
Are the headlight bulbs replaceable on the 2020 Audi S8?
The chart shows LED for the headlight high beam and low beam functions. On many LED-equipped Audi applications, the light source may be integrated into the headlamp assembly, so replacement can involve the module or assembly rather than a standard loose bulb.
What bulb does the glove box light use on the 2020 Audi S8?
The glove box light is listed as 2825, 98. Check the installed bulb before ordering, since interior fitment can vary with equipment and market.
What bulb does the interior door light use?
The interior door light is listed as 2825, 98 as well. As with other interior lights, it is best to confirm the original bulb shape and connector before purchase.
Are the dome light and map light bulbs LED on this model?
Yes, the 2020 Audi S8 is listed with LED dome lights and LED map lights. In many cases, these are not traditional replaceable incandescent bulbs.
What should I know about the rear turn signal and backup light fitment?
Both the rear turn signal light and the back up reverse light are listed as LED on the 2020 Audi S8. If a light fails, you may need to service the LED unit or assembly rather than replace a standard bulb.
Can trim or lighting package changes affect bulb fitment?
Yes. Trim level, lighting package, market, and body style can all affect the exact bulb setup on the 2020 Audi S8. Always match your vehicle’s installed lighting to the chart on this page.
Do aftermarket LED replacements always work in the 2020 Audi S8?
Not always. Aftermarket LED conversions can cause fitment issues, beam pattern problems, or dashboard warnings if they are not designed for the Audi’s electrical system. Compatibility should be checked carefully before buying.
How can I confirm the correct bulb before ordering?
The safest method is to inspect the installed bulb or light module first, then compare it with the bulb chart for your specific lighting position. This is especially important for LED-equipped exterior lights and for interior bulbs like the glove box or door lights.
Are the license plate lights and parking lights LED on the 2020 Audi S8?
Yes, both the license plate light and parking light positions are listed as LED on this model. If one stops working, the repair may involve the LED unit rather than a simple bulb change.
Does the 2020 Audi S8 have separate front and rear side marker bulbs?
Yes, the chart lists both front and rear side marker light bulbs as LED. Confirm the exact side and position before ordering replacement parts.
