The Kia Sedona tail light utilizes 2357 and P21/5W bulb sizes for the rear illumination components. Available information covers the specific time period starting in 2002 and ending in 2021.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 2357 bulb is the most frequently specified size across the Kia Sedona tail light positions, appearing in both the inner and outer tail light positions for the 2019-2020 model years with halogen capsule headlamps, as well as the outer tail light across model years spanning 2002-2018.
The 2357 is an ANSI-standard dual-filament bulb rated at 12V with a high-filament draw of 26.9W and a low-filament draw of 8W, mounted on a BAY15d bayonet base.
The P21/5W is an ECE-standard dual-filament signalling bulb also using a BAY15d bayonet base, rated at 12V with filaments drawing 21W and 5W respectively.
Although the 2357 and P21/5W share the same BAY15d bayonet base, their wattage ratings differ, with the 2357 drawing notably more power on its primary filament (26.9W) compared to the P21/5W (21W).
The 2357 is described as a brighter variant of the 1157, meaning the two bulbs share the same base type but are not identical in output, and substituting one for the other may affect brightness.
For the Kia Sedona, the inner tail light position is only specified for the 2019-2020 model years, where the 2357 bulb applies exclusively under the halogen capsule headlamp configuration.
The outer tail light of the 2021 Kia Sedona uses the P21/5W rather than the 2357, representing a shift from the ANSI standard to the ECE standard for that position.
The halogen capsule headlamp condition noted for the 2019-2020 model years indicates that the 2357 specification for both inner and outer tail light positions is tied to a specific headlamp configuration on those vehicles.
