Additional Notes

The 1157 is the dominant tail light bulb type across the Kia Sorento's listed model years, appearing in 2003-2009 and 2021-2024.
The 1157 is an ANSI-standardized dual-filament bulb operating at 12V with a 21W high filament and a 5W low filament, mounted on a BAY15d bayonet base.
The dual-filament design of the 1157 allows a single bulb to serve two functions, typically combining stop light and tail light operation within one housing.
The 2357 is the specified tail light bulb for the 2018 Kia Sorento, representing a departure from the 1157 used in surrounding model years.
The 2357 shares the same BAY15d bayonet base and 12V operating voltage as the 1157 but draws more power, rated at 26.9W on the high filament and 8W on the low filament.
Because the 1157 and 2357 share the BAY15d base, they are physically interchangeable in terms of fitment, though their wattage outputs differ.
Substituting a 1157 in place of the 2357 specified for the 2018 Sorento would result in reduced brightness, as the 1157 produces less output on both filaments.
Both the 1157 and 2357 are governed by ANSI standards applicable in the United States and Canada, indicating consistent base and voltage specifications across the two types.
