Additional Notes

The 7443 is a dual-filament wedge bulb following the T20 form factor, rated at 12V with a 21W high filament and 5W low filament, conforming to ANSI standards applicable in the US and Canada.
The 2357 uses a BAY15d bayonet base and operates at 12V, with a 26.9W high filament and 8W low filament, also conforming to ANSI standards for the US and Canada.
The 2357 is a brighter variant of the 1157 bulb, sharing the same BAY15d base, which means the two types are physically interchangeable in many applications, though their differing wattage outputs produce different light intensities.
The Hyundai Santa Fe Sport uses the 2357 bulb for the 2013-2016 model years and transitions to the 7443 for 2017-2018.
The 7443 and 2357 are not interchangeable with each other, as the T20 wedge base and the BAY15d bayonet base are mechanically incompatible socket types.
Both bulb types carry dual-filament designs, a configuration typical of tail light assemblies that serve combined stop and running light functions through separate filaments within a single bulb.
