Audi SQ5 2015 Bulb Size
Bulb size chart
This 2015 Audi SQ5 bulb guide helps you verify the correct bulb sizes by lighting position, so you can replace a failed lamp without guessing. Whether you are changing an exterior signal bulb or an interior courtesy light, the goal is to match the bulb to the exact location on the vehicle.
The 2015 Audi SQ5 uses a mix of LED and halogen-style bulbs depending on the lamp position, and some applications can vary by market or package. Use this page as a fitment reference for the common bulb locations on the SQ5 and compare the listed bulb type with what is installed on your vehicle before ordering.
Fitment can differ between trims, lighting packages, and body style details, so it is smart to confirm the bulb in the housing before buying replacements. Some positions on the 2015 Audi SQ5 are listed as LED, while others use serviceable bulbs such as D3S, H11, H16, 921, 2825, 98, 2821, 6411, 6428, or 6418. If you are considering an aftermarket LED conversion for a halogen position, check beam pattern, polarity, and space inside the housing, since not every upgrade will fit or perform correctly. For the most reliable result, compare the installed bulb, connector shape, and housing type first, especially on front fog lights, reverse lights, and interior lamps.
