Questions
What is the Audi A3 low-beam bulb?
2022 Audi A3 stores D4S for the halogen low beam. Choose the LED headlight configuration separately when the chart lists one. These are not installed together.
What is the Audi A3 high-beam bulb?
2022 stores D4S for the halogen high beam.
What fog light bulb does the Audi A3 use?
2022 stores H11 for fog lights.
What does an LED record mean?
A stored part of LED means that configuration is recorded as an LED assembly. It is not a replaceable halogen bulb, and this page does not sell an LED conversion as the OEM bulb for that assembly.
How are HID bulbs handled?
D-series capsules such as D1S or D3S are HID. Exact catalog matches for those positions use HID products, not halogen bulbs.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
Does the Audi A3 bulb chart change by year?
