Additional Notes

The 168 bulb is the specified parking light size for the Hyundai Ioniq across the 2017-2020 model years, exclusively in vehicles equipped with halogen capsule headlamps.
The 168 is an ANSI-standardized bulb type recognized across the United States and Canada, ensuring consistent availability within those markets.
This bulb follows the T10 wedge form factor, a miniature wedge base design that connects by pressing directly into a socket without requiring a twist or pin alignment.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of parking and position light applications rather than primary illumination functions.
The halogen capsule headlamp condition attached to each model year entry indicates that the 168 fitment applies only to that specific headlamp configuration and is not a universal specification across all Ioniq trim variants.
