Audi TT 2022 Bulb Size
Bulb size chart
If you are looking up bulb sizes for the 2022 Audi TT, this page is designed to help you verify the correct bulb type by lighting position. The TT uses a mix of exterior and interior lighting locations, and the exact setup can vary by trim, market, and body style, so checking each position individually is the safest way to confirm fitment.
For the 2022 Audi TT, many exterior lighting functions are listed as LED, while a few interior and cargo-area positions use 2825 bulbs. That makes it especially important to match the bulb to the specific lamp location, whether you are replacing a license plate light, a dome light, a turn signal, or a glove box bulb.
Before buying replacement bulbs, compare the installed bulb and housing style with the chart on this page, since trim and lighting package differences can change what is fitted from one TT to another. Some positions may be factory LED assemblies rather than serviceable bulbs, and aftermarket LED conversions can require the correct base, polarity, or resistor setup to avoid warning messages or flicker. If your car has been modified, or if you are unsure whether a lamp is halogen or LED from the factory, inspect the existing bulb first and confirm the part by position before ordering.
FAQ
Does the 2022 Audi TT use the same bulb sizes on every trim?
Not always. Trim level, lighting package, market, and body style can affect the exact bulb setup on the 2022 Audi TT, so it is best to verify each lighting position rather than assume every car is identical.
Which exterior lights on the 2022 Audi TT are listed as LED?
The page shows LED for the fog light front, high beam headlight, low beam headlight, daytime running light, parking light, tail light, brake light, front and rear turn signals, license plate light, back up reverse light, center high mount stop light, cornering light, and front and rear side marker lights.
What interior bulb type is used in the 2022 Audi TT?
Several interior and utility locations are listed as 2825 bulbs, including the glove box light, trunk or cargo area light, and interior door light bulb where equipped.
Are the 2022 Audi TT headlights replaceable with a standard bulb?
The chart lists both low beam and high beam as LED, which often means the light source is part of an LED assembly rather than a simple plug-in halogen bulb. Check the housing before purchase to confirm whether your specific car uses a serviceable bulb or a sealed LED unit.
How do I verify the correct bulb for the license plate light on a 2022 Audi TT?
Use the lighting position on the page and compare it to the bulb installed in your car. The license plate light is listed as LED, so the replacement may be an LED module or integrated assembly rather than a traditional replaceable bulb.
Can I convert my 2022 Audi TT to aftermarket LED bulbs?
Yes, in some positions you can, but fitment depends on the socket, polarity, and whether the car monitors bulb load. Aftermarket LED conversions may need additional parts to prevent flickering, error messages, or uneven brightness.
Why does my 2022 Audi TT show a bulb warning after replacement?
A warning can happen if the replacement bulb draws less power than the original, is installed backward, or does not match the factory lighting system. This is more common with aftermarket LED conversions than with direct factory-style replacements.
What bulb should I check for the glove box light on the 2022 Audi TT?
The glove box light is listed as a 2825 bulb. If your glove box lamp is out, confirm the installed bulb size and base before ordering a replacement.
Are the dome light and map light bulbs the same on the 2022 Audi TT?
The page lists both dome light and map light as LED, but that does not always mean they use the same exact service part. Check the specific lamp location and housing style before buying a replacement.
Do rear turn signals and front turn signals use the same bulb type on the 2022 Audi TT?
Both front and rear turn signal light bulbs are listed as LED on this page. Even so, the physical lamp design can differ, so confirm the position and fitment before ordering.
What should I do before replacing bulbs on my 2022 Audi TT?
Inspect the existing bulb or lamp assembly, match it to the position listed on the page, and confirm whether the car has factory LED lighting or a serviceable bulb. This is the best way to avoid ordering the wrong part.
