Front Turn Signal

Years	Bulb Size
2022-2024	PY21W

Description	Bulb Size
ECE standard (Europe & worldwide). Single-filament amber bulb with BAU15s bayonet base. 12V, 21W.	PY21W

The PY21W is the front turn signal bulb used across all listed Kia Carnival model years (2022-2024).
The PY21W operates on 12 volts and draws 21 watts, placing it in the standard single-filament category for turn signal applications.
The PY21W 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. This offset distinguishes it from the visually similar BA15s base, and the two are not interchangeable despite their close resemblance.
The PY21W is governed by ECE regulations, a standard recognized across Europe and many other markets worldwide, which mandates the amber output directly from the light source.
