This page helps you find the right bulb sizes for the 2014 Audi S4 by lighting position, so you can match each lamp to the correct replacement before you buy. Whether you are replacing an exterior bulb or a small interior lamp, checking by location is the easiest way to verify fitment for this model.

The 2014 Audi S4 uses a mix of LED lighting and traditional replaceable bulbs depending on the function and equipment level. That means some lights are listed as LED assemblies, while others use specific bulb types such as D3S, 921, 2825/98, 6411/6428, 6418, and 64132 for different areas of the car.

Fitment can vary by trim, lighting package, market, and body style, so it is smart to compare the bulb listed for your exact vehicle with the bulb already installed. This is especially important when dealing with halogen versus LED setups, factory xenon or LED conversions, and aftermarket upgrades that may change the socket or bulb style. Before ordering, check the old bulb, confirm the connector shape, and make sure the replacement matches both the base and the lighting function.

FAQ

What bulb does the 2014 Audi S4 use for the low beam and high beam headlights?

The listed headlight bulb for both high beam and low beam on the 2014 Audi S4 is D3S. Always verify your headlamp type before ordering, since lighting equipment can differ by market or package.

What is the reverse light bulb size for the 2014 Audi S4?

The back up reverse light bulb is 921 on this page. If your car has been modified or fitted with aftermarket lighting, confirm the installed bulb before replacing it.

Are the brake lights on the 2014 Audi S4 replaceable bulbs?

The brake light bulb is listed as LED. On many Audi applications, that means the light may be part of an LED assembly rather than a simple removable bulb, so check the housing before buying parts.

What bulb size is used for the license plate lights?

The license plate light bulb is listed as LED. If one side is out, inspect whether the issue is the LED module, the housing, or wiring rather than a standard bulb socket.

What bulb does the front turn signal use on the 2014 Audi S4?

The front turn signal light bulb is listed as 64132. This is one of the key fitment items to verify by position because front and rear signal bulbs are not always the same.

What bulb is used for the rear turn signal?

The rear turn signal light bulb is listed as LED. Because rear lighting can be integrated into an LED unit, replacement may involve the full assembly instead of a separate bulb.

Which bulb fits the map lights in the cabin?

The map light bulb is listed as 2825 or 98. These small interior bulbs are commonly shared with other cabin positions, but you should still confirm the installed bulb before purchase.

What bulb size is used for the dome light?

The dome light bulb is listed as 6411 or 6428. Either size may appear depending on the exact interior lamp setup, so checking the original bulb is recommended.

What bulb fits the glove box light and trunk light?

Both the glove box light bulb and the trunk or cargo area light are listed as 2825 or 98. These are useful to replace together if you want consistent interior lighting.

Does the 2014 Audi S4 use LED daytime running lights?

Yes, the daytime running light bulb is listed as LED. On this model, the DRL may be part of an LED system, so replacement method can differ from a standard bulb swap.

What should I know before buying replacement bulbs for this car?

Check whether your 2014 Audi S4 has factory LED, xenon, or halogen-related components, then compare the bulb position on this page with the bulb already in the car. Trim and lighting package differences can change fitment, especially for exterior lamps.

Can aftermarket LED conversions change bulb fitment on the 2014 Audi S4?

Yes. Aftermarket LED conversions can alter socket compatibility, beam pattern, and warning behavior. If your car has been converted, use the installed bulb and connector as the final reference instead of relying only on factory listings.
