Audi S4 2010 Bulb Size
Bulb size chart
This 2010 Audi S4 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Whether you are replacing a burned-out exterior lamp or refreshing interior lighting, this page organizes the common bulb types used on the 2010 Audi S4 in a simple, position-by-position format.
Because trim, lighting package, body style, and market can vary, the listed bulb sizes should be used as a fitment reference rather than a guess. Checking the bulb location first makes it easier to confirm whether your S4 uses the same size as the chart before you order replacements.
For the best fit, compare the bulb in your car with the listing on this page before purchasing, especially if your S4 has a different trim or lighting package. Some positions may use LED assemblies, while others may use replaceable halogen-style bulbs, and aftermarket LED conversions can change the required bulb type or create fitment issues. If your vehicle has been modified, or if a previous owner installed non-original bulbs, the installed bulb may not match the factory specification. When possible, remove the old bulb and verify the base, connector, and shape before buying a replacement.
