Additional Notes

The 1157 and P21/5W bulbs share the same BAY15d bayonet base and operate at identical wattages of 21W/5W at 12V, yet they follow different regional standards. The 1157 conforms to the ANSI standard used in the US and Canada, while the P21/5W conforms to the ECE standard used in Europe and worldwide markets.
The 2357 is a dual-filament bulb with a BAY15d bayonet base rated at 26.9W/8W, making it a higher-output variant compared to the 1157. Both share the same base type, though the difference in wattage means they are not direct equivalents in all applications.
The Hyundai Santa Fe outer tail light used the 1157 from 2005-2012, then transitioned to the 2357 from 2013-2018, before shifting again to different bulb types in later model years. The 2013 model year specifically used the 2357 only in vehicles produced from December 10, 2012 onward.
For the 2019-2020 Santa Fe, the outer tail light fitment varies by headlamp configuration. Vehicles equipped with halogen capsule headlamps take the 12961, while the standard 2019 fitment also lists the P21/5W alongside the 12961, indicating multiple possible configurations within that model year.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base, rated at 12V and 5W. This is a single-filament wedge-type bulb, which differs fundamentally in both base type and filament count from the dual-filament BAY15d bulbs used in other model years.
The 2021 and 2023 Santa Fe outer tail light specifications list the 1157, representing a return to the ANSI dual-filament BAY15d bulb after the 12961 wedge bulb was specified for 2022.
The BAY15d base is shared across the 1157, P21/5W, and 2357 bulb types. Despite this shared base, the wattage differences between these types mean substitution between them can affect brightness and may not be appropriate in all fitments.
The 2001 Santa Fe outer tail light used the 1157, while the 2002-2004 models used the 2357. Both use the BAY15d base, but the wattage ratings differ, making them distinct specifications despite their physical compatibility at the socket level.
