The Audi 200 front and rear turn signal bulbs both utilize a P21W size. The replacement chart covers 1989 to 1991 model production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The P21W is the sole bulb type across all listed turn signal positions on the Audi 200, covering model years 1989-1991 for both front and rear applications.
The P21W operates at 12 volts and draws 21 watts, which is the standard wattage for single-filament automotive signalling bulbs under ECE regulations.
P21W bulbs use a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin offset to one side, which prevents incorrect insertion.
The P21W is classified as a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that handle two functions such as braking and running light simultaneously.
The P21W carries ECE certification, indicating it meets the regulatory standards used across Europe and numerous other markets worldwide.
Because the Audi 200 uses the same P21W specification at both the front and rear turn signal positions, the bulbs are physically interchangeable between those locations.
