This page helps you find the right bulb sizes for the 2016 Audi A4 by lighting position, so you can verify each exterior and interior lamp before ordering replacements. Because Audi used different lighting setups depending on trim, market, and body style, checking the exact location is the safest way to match the correct bulb.

For the 2016 Audi A4, many exterior lights are LED-based, while a few serviceable bulbs still use specific part numbers such as 921 for the back up reverse light and D3S for the high beam and low beam headlight bulb. Interior locations also use a mix of common bulb types, including 2825/98, 6411/6428, 6418, and 64132 depending on the lamp position.

Fitment can vary by trim package, lighting package, and whether your A4 has halogen, xenon, or LED equipment from the factory, so always compare the bulb chart with the bulb actually installed in your car. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and physical clearance are correct, especially in tighter housings. Before buying, remove one bulb and confirm the marking on the glass or base, since previous repairs or market-specific equipment can change what is installed.

FAQ

What bulbs does the 2016 Audi A4 use for the headlights?

The listed headlight bulb for the 2016 Audi A4 is D3S for both high beam and low beam. That applies to vehicles equipped with the corresponding factory xenon-style headlight setup.

Are the brake lights on the 2016 Audi A4 LED?

Yes, the brake light bulb position on this page is listed as LED. On many A4s, the rear lighting is integrated into LED assemblies rather than using a simple replaceable incandescent bulb.

What is the reverse light bulb size for a 2016 Audi A4?

The back up reverse light bulb is listed as 921. If your A4 has a different rear lamp configuration, confirm the installed bulb before ordering.

What bulb does the license plate light use?

The license plate light bulb is listed as LED for the 2016 Audi A4. In many cases, this means the light is part of an LED module rather than a standard replaceable bulb.

Do all 2016 Audi A4 trims use the same bulb sizes?

Not always. Trim level, lighting package, market region, and body style can affect the bulb setup, especially for exterior lighting. Always match the bulb position on the page to your specific vehicle.

What are the common interior bulb sizes on this A4?

Several interior locations use common bulb types such as 2825/98 for the glove box, trunk or cargo area, map light, and interior door light. The dome light uses 6411 or 6428, and the vanity mirror light uses 6418.

Is the front turn signal bulb the same as the rear turn signal bulb?

No. The front turn signal bulb is listed as 64132, while the rear turn signal bulb is listed as LED. They are different fitments and should not be assumed interchangeable.

Can I replace an LED exterior light with a standard bulb?

Usually no. Many exterior positions on the 2016 Audi A4 are LED assemblies, so they are not direct plug-in replacements for standard bulbs. If the lamp is an LED module, the entire unit or module may need service instead of just the bulb.

What should I check before buying replacement bulbs?

Check the exact bulb position, confirm whether the lamp is LED or replaceable, and compare the installed bulb number if accessible. It is also smart to verify the connector style and housing space before ordering aftermarket parts.

Does the 2016 Audi A4 use the same bulb for map lights and trunk lights?

Yes, both the map light and trunk or cargo area light are listed as 2825/98 on this page. Even so, it is still a good idea to confirm the installed bulb before purchase.

Why does the bulb chart mention different lighting setups?

Audi used different equipment depending on market and package options. That is why the chart is organized by lighting position, helping you verify the correct bulb for your exact 2016 Audi A4 rather than relying on a single generic list.

What is the safest way to replace a bulb on my 2016 Audi A4?

Use the bulb size listed for that specific location, turn the lights off, let the lamp cool if needed, and handle bulbs carefully to avoid damage. For LED or integrated lighting, confirm whether the bulb can be replaced separately or whether the full assembly is required.
