Kia Sephia Courtesy Bulb Size

Additional Notes

• The 168 bulb is the sole courtesy bulb size listed for the Kia Sephia across all model years covered in the specifications, spanning 1994-2001.
• The 168 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across North American markets.
• It is classified as a miniature wedge bulb, a type that uses a wedge-shaped base inserted directly into a socket without a separate metal cap or pins, relying on tension from the socket to maintain contact.
• The T10 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, placing it at 10/8 or 1.25 inches wide.
• The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
• Its rated wattage of 4.9W places it in the low-power range typical of interior courtesy lighting, where heat output and current draw are kept minimal.
• Because the 168 bulb type remains unchanged across all eight model years in the specifications, courtesy bulb replacement parts sourced for any one of those years are electrically and physically interchangeable with the others.
