Additional Notes

The Audi SQ5 Sportback uses the D5S bulb across all listed low beam headlight positions for 2021, 2023, and 2024, making it the most consistently specified bulb type in these fitment records.
The D5S is an HID (high-intensity discharge) xenon bulb operating at 12V and 25W, built to ECE standards for use in Europe and worldwide markets. It uses a PK32d-7 base and is classified as a low-voltage compact type within the HID category.
The lower wattage of the D5S (25W) relative to halogen alternatives reflects the higher luminous efficiency of HID technology, where greater light output is achieved at reduced power consumption.
The high beam headlight position shows a split between two bulb types across the listed years: the H8 is specified for 2021 and 2024, while the 9006 is specified for 2023.
The H8 is a single-filament halogen bulb rated at 12V and 35W, using a PGJ19-1 base. It conforms to ECE standards and carries approval for use in the United States as well.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, using a P22d base. It follows the ANSI standard applicable to the US and Canada.
The H8 and 9006 are not interchangeable. Their base types differ (PGJ19-1 versus P22d), and their wattage ratings differ by 20W, meaning a direct substitution between the two is not supported by their respective specifications.
The 2023 Audi SQ5 Sportback high beam specification calls for the 9006, which draws 55W compared to the 35W H8 used in the 2021 and 2024 model years, representing a notable difference in power draw for the same functional position.
