Additional Notes

The 904 and 168 are both ANSI-standardized miniature wedge bulbs sharing the T10 form factor, meaning they occupy the same physical socket type despite differing in wattage.
Although the 904 and 168 share the T10 socket, they are not interchangeable as direct replacements due to their different wattage ratings: the 904 operates at 12V and 8W, while the 168 operates at 12V and 4.9W.
The Kia Sorento uses the 904 bulb across the 2007-2009 model years specifically in vehicles without a sunroof, indicating that sunroof-equipped trims of those years follow a different fitment.
The 2018 Sorento specifies the 904 bulb for the front map light position, reflecting a multi-zone interior lighting layout for that model year.
The 904 bulb is the more prevalent type across the listed specifications, appearing in the 2007-2009, 2018, 2022, and 2023 model years.
The 168 bulb at 4.9W draws notably less power than the 904 at 8W, a distinction relevant when sourcing LED equivalents, as replacement LED bulbs are typically rated to match the original wattage class of the socket.
The Kia Sorento transitioned from the 168 bulb used in the 2003-2006 model years to the higher-wattage 904 bulb in subsequent listed years, representing a shift in the map light specification between those production periods.
