Kia Sedona Stepwell Bulb Size

Additional Notes

• The 12961 is the sole stepwell bulb size listed across all model years of the Kia Sedona covered in these specifications.
• The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and 5 watts.
• The T10 designation refers to the bulb's tubular glass envelope, with the number indicating a width of ten eighths of an inch.
• The W2.1x9.5d base type is a wedge-style base, meaning the bulb is held in its socket by the tension of the socket walls rather than by a bayonet or screw mechanism.
• At 5 watts, the 12961 is a low-output bulb suited to interior courtesy lighting functions such as stepwell illumination rather than high-visibility exterior applications.
• The Kia Sedona covered by these specifications spans the 2002-2014 model years, with the 12961 fitment consistent across that entire range.
• The 2014 model year entry carries a production cutoff of April 1, 2014, indicating this specification applies only to vehicles assembled up to that date within that model year.
• The 2006 model year entry specifies a fitment window running from September 1, 2005 through December 31, 2006, reflecting a mid-cycle production boundary rather than a full calendar year.
• Because the W2.1x9.5d wedge base is a standardized interface, other T10 wedge bulbs sharing that base type are generally considered interchangeable with the 12961, provided voltage and wattage ratings are compatible with the vehicle's socket.
