Audi TT 2002 Bulb Size
Bulb size chart
This page lists the bulb sizes for the 2002 Audi TT by lighting position, so you can quickly confirm the correct replacement before you buy. Because trim and lighting equipment can vary, the exact bulb used on your TT may depend on body style, market, and whether the car has halogen or HID headlights.
Use the chart below as a position-by-position reference for exterior and interior lights such as the low beam, fog lights, parking lights, license plate lights, dome light, map light, and cargo area bulbs. Matching the bulb to the correct location is the easiest way to avoid ordering the wrong part.
For best results, compare the bulb size on this page with the bulb already installed in your car before purchasing, especially if your TT has an optional lighting package or has been modified with aftermarket parts. The 2002 Audi TT may use different low beam bulbs depending on whether it has halogen headlights or HID headlights, and LED conversions can change fitment, beam pattern, or bulb warning behavior. If your car has been converted from stock lighting, verify the socket style and the physical bulb shape, not just the original factory listing. When in doubt, remove the old bulb and check the number printed on the base or glass before ordering replacements.
