This 2015 Audi SQ5 bulb guide helps you verify the correct bulb sizes by lighting position, so you can replace a failed lamp without guessing. Whether you are changing an exterior signal bulb or an interior courtesy light, the goal is to match the bulb to the exact location on the vehicle.
The 2015 Audi SQ5 uses a mix of LED and halogen-style bulbs depending on the lamp position, and some applications can vary by market or package. Use this page as a fitment reference for the common bulb locations on the SQ5 and compare the listed bulb type with what is installed on your vehicle before ordering.
Fitment can differ between trims, lighting packages, and body style details, so it is smart to confirm the bulb in the housing before buying replacements. Some positions on the 2015 Audi SQ5 are listed as LED, while others use serviceable bulbs such as D3S, H11, H16, 921, 2825, 98, 2821, 6411, 6428, or 6418. If you are considering an aftermarket LED conversion for a halogen position, check beam pattern, polarity, and space inside the housing, since not every upgrade will fit or perform correctly. For the most reliable result, compare the installed bulb, connector shape, and housing type first, especially on front fog lights, reverse lights, and interior lamps.
FAQ
What bulb does the 2015 Audi SQ5 use for the low beam and high beam headlights?
The listed headlight bulb for both high beam and low beam is D3S. Always confirm the exact headlamp setup on your SQ5 before ordering, since lighting packages can affect fitment.
What is the front fog light bulb size on a 2015 Audi SQ5?
The front fog light bulb is listed as H11 LED or H16 LED. The correct choice can depend on the specific lamp housing and market configuration, so check the installed bulb and connector before replacing it.
What bulb fits the rear reverse light on this model year?
The back up reverse light bulb is 921. This is a common service bulb, but it is still best to verify the old bulb number before purchase.
Are the brake lights and tail lights LED on the 2015 Audi SQ5?
Yes, the brake light bulb and tail light bulb are listed as LED. In many cases these are integrated LED assemblies rather than simple replaceable bulbs, so inspect the lamp design before assuming a standard bulb swap.
What bulb is used for the license plate lights?
The license plate light bulb is listed as LED. If one side fails, check whether the issue is the LED module, wiring, or a complete lamp assembly.
What bulb size is used for the interior map lights?
The map light bulb is listed as 2825 or 98. These same bulb types are also used in several other interior positions on the SQ5.
Which interior bulbs use 2825 or 98 on the 2015 SQ5?
According to the bulb chart, 2825 or 98 is used for the trunk or cargo area light, map light, interior door light, and rear reading light. That makes it easier to buy a matching set for multiple interior replacements.
What bulb is used for the dome light?
The dome light bulb is listed as 6411 or 6428. Check the existing bulb and the dome housing style, because some vehicles may use one of the two listed options.
What bulb fits the glove box light?
The glove box light bulb is 2821. This is a small interior bulb, so handle the lens and socket carefully during replacement.
What bulb is used for the side marker lights?
The front side marker light bulb is listed as LED, while the rear side marker light bulb is 2821. Since the front and rear use different types, verify the exact location before ordering.
Does the 2015 Audi SQ5 use different bulbs for the daytime running lights and parking lights?
Yes. The daytime running light bulb is listed as LED, and the parking light bulb is also listed as LED. These may be part of a larger lighting module, so confirm whether the lamp is serviceable or integrated.
Can I replace the factory bulb with an aftermarket LED on the 2015 SQ5?
In some positions, yes, but fitment and performance depend on the housing, socket, and electrical compatibility. Aftermarket LED conversions can cause glare, warning messages, or poor beam pattern if they are not matched correctly.
