Additional Notes

The Kia Rio5 uses the 881 bulb for the front fog light position across the 2006-2011 model years.
The 881 is a single-filament halogen bulb, meaning it serves one lighting function only and does not combine roles such as low and high beam within a single unit.
It operates on a 12-volt electrical system at 27 watts, which is consistent with standard automotive low-voltage DC power supplies.
The 881 bulb uses a PGJ13 base, a pin-type base format where the two pins are separated by 13 millimeters, and this base type is not interchangeable with other common fog light bases such as H11 or H8.
The 881 designation follows ANSI standardization, meaning the bulb specification is recognized across both the United States and Canada under a shared technical standard.
Because the PGJ13 base is specific to a narrow range of bulb types, substituting a bulb with a different base configuration would require a socket adapter or would not physically fit the housing.
The 27-watt rating of the 881 places it in the lower output range for halogen fog lights, which is typical for auxiliary fog lighting rather than primary forward illumination.
The consistent use of the 881 across all six model years indicates no mid-cycle change to the fog light socket or housing specification for the Rio5 during this production period.
