The Kia Sephia map light requires a 168 bulb size for the interior lighting system. Data for the specified bulb covers the range from 1994 to 2001.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Bulb Size by Year Range

Years	Bulb Size
1994-2001	168

Description	Bulb Size
ANSI standard (US & Canada). Miniature wedge bulb (T10). 12V, 4.9W.	168

The 168 bulb is the sole map light bulb size listed for the Kia Sephia across all model years in the specifications, covering 1994-2001.
The 168 bulb follows the ANSI standard recognized in the United States and Canada, placing it within a regulated classification system for miniature automotive lamps.
It belongs to the T10 form factor, a miniature wedge-base bulb type that seats without a separate socket pin, relying instead on the tapered plastic base to make electrical contact.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 4.9 watts, the 168 produces a relatively low power draw, which is typical for interior courtesy and map lighting applications where prolonged use is common.
The T10 wedge base is a widely used form factor, and multiple bulb numbers share this physical base style. However, wattage and voltage ratings differ between part numbers, so substitutions require verification against the 12V, 4.9W rating of the 168.
