Additional Notes

The PY21W is an ECE-standard single-filament bulb rated at 12V and 21W. It produces amber light natively, meaning the bulb itself is tinted rather than relying on a colored lens to achieve the required turn signal color.
The PY21W uses a BAU15s bayonet base, which has offset pins to prevent incorrect installation. This base is not interchangeable with the more common BA15s or BAY15d bases found on other automotive bulbs.
The Hyundai Santa Cruz uses the PY21W for its turn signal application across the 2023-2024 model years.
