Additional Notes

The 2357 bulb is the most frequently specified brake bulb across the Kia Sportage range, appearing in brake light applications from 2005 through 2020. It is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively, making it a higher-output variant of the 1157.
The 1157 bulb shares the same BAY15d bayonet base as the 2357 but operates at lower wattages of 21W and 5W. Both bulbs use identical base configurations, though their filament wattages differ, which means they are not directly interchangeable despite the physical similarity of their bases.
The Kia Sportage (1995-2002) uses the 1157 for brake lighting, while the 2357 takes over from 2005 onward. The shared BAY15d base between these two types is a known source of fitment errors, as one can be physically inserted in place of the other.
From 2014-2019, the standard brake position specifies the 2357 with a conditional note for vehicles equipped with Halogen Capsule Headlamps, indicating that headlamp configuration is a relevant fitment variable for those model years.
The 2020 Outer Brake position also carries the Halogen Capsule Headlamps condition for the 2357, while the 2019 Outer Brake position lists the 2357 without that condition, reflecting a distinction between the two sub-part entries for overlapping years.
The 921 is a single-filament wedge bulb of the T15 type, rated at 12V and 16W. It appears in the standard brake position for the 2023 model year and in the Center High Mount Stop Light for 1995-1998, representing a physically distinct base type from the BAY15d bulbs used elsewhere in the same vehicle line.
The 168 is a miniature T10 wedge bulb rated at 12V and 4.9W. Its application is limited to the Center High Mount Stop Light for 2011-2016, where its low wattage reflects the reduced power demands typical of a supplementary stop light position.
The Center High Mount Stop Light transitions from the 921 bulb in 1995-1998 to the 168 bulb in 2011-2016, with both being wedge-type bulbs that are nonetheless incompatible with each other due to differing base sizes and wattage ratings.
