Additional Notes

The Hyundai Palisade rear turn signal uses two distinct bulb standards across its production years: the 2357 (ANSI) and the PY21W (ECE). These standards are regionally defined, with ANSI applying to the US and Canada and ECE applying to Europe and worldwide markets.
The 2357 bulb is a dual-filament type rated at 12V with a high/low wattage split of 26.9W and 8W. It uses a BAY15d bayonet base, which features two offset pins to prevent incorrect installation.
The PY21W is a single-filament amber bulb rated at 12V and 21W. It uses a BAU15s bayonet base, where the single offset pin distinguishes it physically from other BAY15-family bases.
The BAU15s base of the PY21W and the BAY15d base of the 2357 are not interchangeable. The pin offset angles differ between the two base types, meaning a bulb from one standard cannot be seated into a socket designed for the other.
The Hyundai Palisade (2020-2023) uses the 2357 bulb for the rear turn signal, while the 2024 model year uses the PY21W.
The 2357 is described as a brighter variant of the 1157 bulb. Both share the BAY15d base, but the 2357 draws more wattage on its primary filament, producing greater output.
The 2020 Palisade rear turn signal fitment of the 2357 is specific to vehicles equipped with halogen capsule headlamps, indicating that headlamp type is a relevant variable for that model year.
