This 2012 Audi TT bulb size guide is designed to help you verify the correct bulb by lighting position before you buy replacement parts. Whether you are changing a headlight, a turn signal, or an interior lamp, matching the bulb to the exact location is the safest way to avoid fitment mistakes.

The 2012 Audi TT uses different bulb types depending on the lamp position, and some items can vary by trim, body style, or lighting package. Use this page to compare the bulb chart for the front, rear, interior, and exterior lights so you can find the right replacement faster.

For the best fit, always confirm your trim and lighting setup before ordering, especially if your TT has a different market specification, optional equipment, or a previous owner’s aftermarket modifications. Some lighting positions may use halogen bulbs in one version and LED components in another, and aftermarket conversions can change the original bulb requirements. If a bulb is hard to identify from the chart alone, remove the installed bulb and check the number printed on the base before purchasing a replacement. That is especially useful for items like the headlight, fog light, parking light, and interior bulbs, where small differences can affect compatibility.
