The 2019 Audi S3 uses different bulb types depending on the lighting position, so the safest way to shop is by matching the bulb to the exact location on the car. This page is designed to help you verify bulb sizes by lighting position, whether you are replacing an exterior lamp or an interior courtesy light.
For the 2019 Audi S3, many exterior lighting functions are listed as LED, while several interior bulbs use common incandescent sizes such as 2825, 98, and 6418. Because trim, market, and body style can affect fitment, always confirm the bulb location before ordering.
Fitment can vary on the 2019 Audi S3 depending on trim level, lighting package, and regional equipment, so do not assume every car uses the same bulb setup. Some cars came with factory LED exterior lighting, while others may differ in how the assembly is configured. If you are considering an aftermarket LED conversion, make sure the replacement is compatible with the socket, polarity, and any bulb monitoring system. It is also smart to check the installed bulb before purchase, especially for interior lights and any position that may have changed during previous repairs.
FAQ
What bulb sizes does the 2019 Audi S3 use for the headlights?
On this page, both the high beam and low beam headlight positions are listed as LED for the 2019 Audi S3. That means the headlamp bulb type is tied to the LED assembly rather than a standard replaceable halogen bulb.
Are the daytime running lights on the 2019 Audi S3 LED?
Yes. The daytime running light bulb position is listed as LED for the 2019 Audi S3. If the DRL is not working, the issue may be in the LED module or assembly rather than a simple bulb swap.

The brake light bulb position is listed as LED. On many Audi applications, this means the brake light is integrated into the lamp assembly, so replacement may involve the full unit instead of a separate bulb.

Yes, both the front and rear turn signal light bulb positions are listed as LED for the 2019 Audi S3. Always confirm whether the signal is part of an integrated lamp assembly before ordering parts.

What should I check before buying replacement bulbs for my 2019 Audi S3?
Check the exact lighting position, verify whether the car has factory LED equipment, and compare the installed bulb or lamp assembly before ordering. This is especially important on the 2019 Audi S3 because trim and lighting package differences can change fitment.
Do trim levels or market differences matter on the 2019 Audi S3?
