Audi A4 2000 Bulb Size
Bulb size chart
This 2000 Audi A4 bulb size guide helps you quickly verify the correct bulbs by lighting position, so you can match the right part before you buy. Whether you are replacing a burned-out interior lamp or checking exterior lighting, this page organizes the common fitments for the A4 in a simple, model-year format.
Use the chart to compare bulb sizes for the headlamps, tail lamps, parking lights, license plate lights, and cabin lights on your 2000 Audi A4. Because lighting equipment can vary by trim, market, and body style, it is always smart to confirm the bulb location first and then match the size listed for that position.
Fitment can change depending on trim level, lighting package, and whether the car uses halogen or HID equipment, so the same 2000 Audi A4 may not use identical bulbs in every market. If you are considering LED replacements or other aftermarket conversions, make sure the bulb style, socket depth, and polarity requirements are compatible with the housing. For the best results, check the installed bulb before ordering, especially for interior lights and any exterior lamp that may have been changed previously.
