Additional Notes

The 9006 is an ANSI-standard single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base. It is the most frequently specified front fog light bulb across the Kia Optima's model history, appearing across 2003-2008, 2013, and 2019.
The 881 is an ANSI-standard single-filament halogen bulb rated at 12V and 27W, fitted with a PGJ13 base. It draws considerably less wattage than the 9006, which reflects a different output level rather than a direct substitution relationship between the two types.
The H8 is an ECE-standard single-filament halogen bulb rated at 12V and 35W, fitted with a PGJ19-1 base. Although it originates from the European ECE regulatory framework, it carries US approval as well.
The 9006, H8, and 881 all share a 12V operating voltage, yet their wattage ratings differ at 55W, 35W, and 27W respectively. These differences mean the three bulb types are not interchangeable despite the shared voltage.
The P22d base of the 9006 and the PGJ19-1 base of the H8 are physically distinct connector types. A bulb with one base type cannot be seated in a socket designed for the other.
The 2019 Kia Optima front fog light specification carries a production date qualifier, applying the 9006 halogen bulb to vehicles produced from 05/04/2018 onward.
The 2011 Kia Optima front fog light has three separate bulb size entries: H8, 9006 applicable from 12/31/2010, and 881 applicable from 5/11/2011. This indicates that the correct bulb type for a given 2011 vehicle depends on its specific production date.
The 2002 Kia Optima front fog light specifications list both the 881 and the 9006, with the 9006 applying from 7/1/2002 and the 881 applying to vehicles produced up to that same date. These two entries represent a mid-year bulb change rather than a choice between alternatives.
The 2008 front fog light specifications include two 9006 entries, one without a date qualifier and one noting production up to 8/31/2008. Both entries reference the same bulb type, indicating no change in bulb size occurred within that model year.
The 2005 front fog light specifications list two 9006 entries, one without a date qualifier and one noting production from 12/1/2005. Both reference the same bulb type, indicating no bulb change took place within that model year.
