Audi Q5 2012 Bulb Size
Bulb size chart
This 2012 Audi Q5 bulb size page helps you verify the correct bulbs by lighting position, so you can replace only the part you need. Whether you are changing a headlight, interior lamp, or rear signal bulb, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The 2012 Audi Q5 uses a mix of LED and halogen-style bulbs depending on the lamp and equipment level. Because trim and lighting package can vary by market and body style, always compare the bulb chart on this page with the bulb already installed in your vehicle before ordering replacements.
For best results, confirm your Q5’s trim, lighting package, and whether the lamp is factory halogen or LED before buying. Some positions may accept more than one bulb type or have different specifications for different markets, and aftermarket LED conversions can change the required fitment or trigger warning messages. If you are unsure, remove the old bulb and match the base, shape, and markings before purchase, especially for exterior lights where the wrong bulb can affect brightness, beam pattern, or legal compliance.

What is the front turn signal bulb size on a 2012 Audi Q5?

What size is the back-up reverse light bulb on a 2012 Audi Q5?
The back-up reverse light bulb is 921. This is a common fitment, but it is still a good idea to compare it with the installed bulb in your vehicle.
Which bulb is used for the brake light and tail light?
Both the brake light bulb and tail light bulb are listed as 7506R. That makes it easier to stock a spare if you want to replace both sides together.
What bulb size is used for the license plate lights?
The license plate light bulb is 6418. If your plate lights are dim or one side is out, replacing both bulbs at the same time is often a smart maintenance step.
What bulb does the 2012 Audi Q5 use for the fog lights?
The front fog light bulb is listed as H11 LED or H16 LED. Because fog light fitment can vary, check the exact lamp and connector style on your vehicle before buying.
Are the interior map lights and dome light the same bulb?
Yes, the map light bulb, dome light bulb, trunk or cargo area light, interior door light bulb, and vanity mirror light bulb are all listed with 2825, 98 or 6418 depending on the position. The exact bulb can differ by location, so match the chart carefully.
What bulb fits the glove box light on the 2012 Audi Q5?
The glove box light bulb is 2821. This is a separate fitment from several other interior lamps, so do not assume it uses the same bulb as the map or dome light.
What bulb is used for the side marker lights?
The front side marker light bulb is listed as 2825, 98, while the rear side marker light bulb is 2821. Front and rear side markers are not the same on this vehicle, so verify the position before ordering.
Does the 2012 Audi Q5 use LED bulbs in some positions?
Yes. The chart shows LED for the center high mount stop light, parking light, daytime running light, and some fog light configurations. That means some exterior lamps may already be LED from the factory, while others use replaceable bulbs.
Why should I check the installed bulb before purchasing replacements?
Checking the installed bulb helps confirm the exact base and size, which is important on the 2012 Audi Q5 because trim and lighting package differences can change fitment. It also helps avoid problems when a previous owner has installed aftermarket bulbs or conversions.
