Bulb size chart
This page helps you verify the bulb sizes for the 2014 Audi A6 by lighting position, so you can match the correct replacement before you buy. Because Audi used different lighting setups depending on trim, package, and headlight type, the exact bulb can change from one A6 to another.
Use the chart to check exterior and interior bulbs separately, including headlights, turn signals, brake lights, license plate lights, reverse lights, and cabin lamps. For the 2014 Audi A6, some positions use LED modules while others use replaceable bulbs such as D3S, H15, 7507, 921, 2825/98, H11/H16 LED, 6411/6428, 6418, 64136, and 6486X.
Fitment on the 2014 Audi A6 can vary by market, body style, and lighting package, so always confirm whether your car has halogen headlights or factory LED headlights before ordering. That matters because several positions use different bulbs depending on the setup, and some LED-equipped cars may use integrated LED units rather than standard replaceable bulbs. If you are considering aftermarket LED conversions, make sure the bulb base, size, and beam pattern are compatible with the housing, especially for headlights and fog lights. The safest approach is to compare this page with the bulb already installed in your vehicle before purchase.
