Additional Notes

The Kia Sedona uses two distinct bulb types across its model years for the back up light position: the 921 and the 1156, both of which are ANSI-standardized bulbs for the US and Canadian markets.
The 921 is a T15 wedge-base bulb rated at 12V and 16W. Its wedge-style base means it is held in place by friction within the socket rather than by a locking mechanism.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. The bayonet mount requires an insert-and-twist motion to seat and release the bulb.
Because the 921 uses a wedge base and the 1156 uses a bayonet base, these two bulb types are not physically interchangeable despite both operating at 12V.
The 1156 draws 21W compared to the 921's 16W, reflecting a difference in power consumption that also corresponds to different socket and wiring configurations between the two generations.
The Kia Sedona (2006-2021) uses the 921 bulb for the back up light, covering the majority of the model's production span represented in these specifications.
The 2002-2005 Kia Sedona uses the 1156 bulb for the back up light, representing the earlier generation of the vehicle.
The model year 2006 marks the transition point from the 1156 to the 921 bulb type in the back up light position, indicating a change in socket design between those two model years.
