Additional Notes

The 12961 is a Philips-designated miniature wedge bulb in the T10 form factor, rated at 12V and 5W with a W2.1x9.5d base. It is the most frequently specified bulb across the Hyundai Elantra side marker positions, appearing in both front and rear applications from 2019-2024 for the front and 2019-2023 for the rear.
The 168 is an ANSI-standard T10 miniature wedge bulb rated at 12V and 4.9W. It shares the same T10 wedge form factor as the 12961 and 194, though its wattage differs slightly from both. It serves as the front side marker bulb for the 2013-2018 Elantra and appears across various rear side marker positions as well.
The 12961 and 168 both occupy the T10 wedge form factor, but the 12961 uses a W2.1x9.5d base designation under the IEC/Philips naming system while the 168 follows the ANSI standard. Despite their physical similarities, these are distinct part numbers and are not listed interchangeably within these specifications.
The 2019-2020 Hyundai Elantra front and rear side marker positions specify the 12961 bulb with a conditional note restricting that fitment to vehicles equipped with Halogen Capsule Headlamps, indicating that headlamp type is a determining factor in side marker bulb selection for those model years.
The rear side marker for the 2016-2018 Elantra carries headlamp-type conditions as well. The 2017-2018 entries specify the 168 for vehicles with Halogen Capsule Headlamps, while the 2014-2016 entries specify the 168 for vehicles without Projector-Type Headlamps, reflecting that trim-level headlamp configurations affect rear marker bulb fitment.
The 2357 and 2357NA are dual-filament bulbs sharing the BAY15d bayonet base and identical 12V, 26.9W/8W ratings. The 2357NA variant uses natural amber glass rather than a clear envelope, which produces the amber color required for side marker applications without relying on a tinted lens. The 2357 appears in rear side marker positions for the 2001-2003 Elantra, while the 2357NA is specified for the front in 2000-1999.
The 1157, specified for the Elantra rear side marker in 1993-1995, is a dual-filament BAY15d bayonet bulb rated at 12V and 21W/5W. The 2357 is a brighter variant of the 1157, sharing the same base and voltage but drawing 26.9W on its high filament rather than 21W. These two bulbs are not listed as interchangeable within these specifications despite their shared base type.
The 97 bulb, specified for both front and rear side marker positions on the 1992 Elantra, is a single-filament bulb with a BA15s bayonet base rated at 12V and 13W. It is described as a variant of the 1156 and uses a different base type than the dual-filament BAY15d bulbs, making it physically incompatible with sockets designed for the 2357, 2357NA, or 1157.
