This 2017 Audi Q5 bulb size guide is designed to help you verify the correct bulb by lighting position, so you can replace the right lamp the first time. Whether you are changing an exterior signal light, a cargo-area bulb, or a cabin light, matching the bulb to the exact location is the safest way to avoid fitment mistakes.
The 2017 Audi Q5 uses a mix of LED and halogen-style bulb types depending on the lamp position and equipment level. On this page, you can check common fitment points such as the headlights, tail lights, license plate lights, reverse lights, fog lights, and interior bulbs for a quick reference before ordering replacements.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm what is actually installed on your vehicle before buying. Some positions on the 2017 Audi Q5 are listed as LED, while others use replaceable bulbs such as 921, D3S, H11 LED, H16 LED, 2825/98, 2821, 6411/6428, or 6418 depending on the lamp. If you are considering an aftermarket LED conversion, check for beam pattern, warning messages, and compatibility with the factory housing. For the best results, compare the bulb in the car with the bulb chart and inspect the old bulb before purchase, especially if your Q5 has optional lighting equipment or a previous owner made changes.
FAQ
What bulb does the low beam and high beam use on a 2017 Audi Q5?
The headlight bulb listed for both high beam and low beam on the 2017 Audi Q5 is D3S. Always confirm your headlamp type before ordering, since factory lighting equipment can differ by market or package.
What is the reverse light bulb size for the 2017 Audi Q5?
The back up reverse light bulb is listed as 921. If one side is out, it is usually a good idea to replace bulbs in pairs when the design and access make that practical.
Which front fog light bulb fits the 2017 Audi Q5?
The front fog light bulb is listed as H11 LED or H16 LED. The exact fit can depend on the lighting setup, so check the installed bulb and connector before purchasing.
Does the 2017 Audi Q5 use LED bulbs for the tail lights and brake lights?
Yes, the bulb chart lists the tail light bulb and brake light bulb as LED. On many Q5 models, these are integrated LED assemblies rather than simple replaceable halogen bulbs.
What bulb size is used for the license plate lights on this Audi Q5?
The license plate light bulb is listed as LED. If you are replacing a failed license plate lamp, verify whether your vehicle uses a serviceable LED module or a complete lamp assembly.
What bulb is used for the rear turn signal on the 2017 Q5?
The rear turn signal light bulb is listed as LED. Because rear lighting can vary by trim and market, it is best to match the exact lamp style already installed on the vehicle.
What about the front side marker light bulb?
The front side marker light bulb is listed as LED. This is another position that may be part of a sealed or integrated lighting unit rather than a standard replaceable bulb.
Which bulbs are used for interior map lights and cargo area lights?
The trunk or cargo area light, map light, interior door light, and rear reading light are listed as 2825 or 98. These are common interior bulb sizes, but you should still confirm the original bulb before ordering.
What bulb fits the dome light and vanity mirror light?
The dome light bulb is listed as 6411 or 6428, and the vanity mirror light bulb is listed as 6418. Interior trim and package differences can affect the exact fit, so checking the installed bulb is recommended.
What bulb size is used for the glove box light and rear side marker light?
The glove box light bulb is listed as 2821, and the rear side marker light bulb is also listed as 2821. These are small interior or marker bulbs that are easy to verify by removing the old bulb.
Are all 2017 Audi Q5 bulbs the same across every trim?
No. Trim level, lighting package, market, and body style can change the bulb setup. Some lamps are LED and some use replaceable bulbs, so the chart should be used as a position-by-position reference rather than a one-size-fits-all rule.
Should I check the old bulb before buying a replacement?
Yes. Checking the installed bulb is the most reliable way to confirm fitment, especially if the vehicle has optional lighting, aftermarket parts, or prior repairs. This is especially important for LED-equipped positions and for fog light or headlight conversions.
