2021 Audi Q8 Bulb Size

If your 2021 Audi Q8 has a burned bulb, finding the right size can feel confusing and waste time. This bulb size list is meant to save that time by putting recommended OEM and common aftermarket bulb codes in one place, so you can quickly identify replacements for headlights, taillights, indicators, and interior lamps. Before using the chart, confirm your exact trim and model year and have the existing bulb code or part number handy. Match codes from the list to the part you remove, and consider the trade-off between OEM fit and aftermarket options under your constraints. Validation comes from cross-checking with your owner’s manual and the physical bulb before ordering.
