Additional Notes

The 168 bulb is the interior door bulb size for the Hyundai Sonata across the 1999-2001 model years.
The 168 bulb follows the ANSI standard, meaning it meets the specifications set by the American National Standards Institute and is rated for use in the US and Canada.
This bulb uses a T10 miniature wedge base, a small single-contact base type that is held in place by friction rather than a locking mechanism.
The 168 bulb operates at 12 volts with a power draw of 4.9 watts, which is consistent with low-current interior lighting applications in passenger vehicles.
The T10 wedge base format is shared across many bulb variants, meaning physically similar bulbs with different wattage or voltage ratings may fit the socket but not meet the original electrical specification.
