Audi TT RS 2013 Bulb Size
Bulb size chart
This page helps you find the correct bulb sizes for the 2013 Audi TT RS by lighting position, so you can replace the right lamp without guesswork. Whether you are changing an exterior signal, a cabin bulb, or a headlight source, matching the bulb to the correct location is the easiest way to avoid fitment mistakes.
The 2013 Audi TT RS uses a mix of LED and halogen-style bulbs depending on the lamp position, and some lighting equipment can vary by market and body style. Use the bulb chart on this page to verify each location before ordering parts, especially if your car has a different trim or lighting package than another TT RS from the same year.
For best results, compare the bulb listed on this page with the one already installed in your car before buying replacements. Trim differences, factory lighting packages, and regional equipment can change what fits, especially on cars that may have halogen versus LED components or aftermarket conversion kits. If your TT RS has been modified, the original bulb type may no longer match the current setup, so checking the existing bulb and connector is the safest way to confirm fitment.
