Additional Notes

The 168 bulb is an ANSI-standardized miniature wedge type, classified under the T10 form factor, and operates at 12 volts with a power draw of 4.9 watts.
The T10 wedge base design requires no separate socket or locking mechanism, as the bulb is held in place by tension from the housing itself.
The Hyundai Tucson uses the 168 bulb for the interior door position across the 2005-2013 model years.
The 168 designation follows ANSI standardization applicable in both the United States and Canada, meaning the specification reflects a regionally consistent fitment.
At 4.9 watts, the 168 bulb falls within the low-wattage range typical of interior courtesy and door lighting applications, where heat output and current draw are kept minimal.
The T10 wedge category includes several bulb numbers that share the same physical base, so substitution with other T10-compatible types is possible only when voltage and wattage ratings are also matched.
